The end is nigh for the modern graphics chip. It genuinely pains me to say that. After all, I’m an unapologetic chip aficionado, someone who loves the technology of integrated circuits for the sake of it. But it’s becoming increasingly apparent that GPUs are over-engineered, increasingly irrelevant and almost definitely not long for this world.

The background here involves a confluence of technological trends. The most ominous of these in terms of the GPU’s longevity as a discrete component is the architectural convergence of CPUs and GPUs. However, one of the most debilitating symptoms of the graphics chip’s terminal malaise is complexity – sheer, pointless complexity. Take Nvidia’s latest uber pixel pumper, the GeForce GTX 480. It weighs in at three billion transistors. That’s getting on for triple the size of Intel’s beefiest PC processor, the six-core Core i7-980X.

If the GTX 480 was any use, that monster transistor count would actually add to the allure. But the harsh truth is that it isn’t – for almost anything. And that makes it dumb. You see, despite the hype regarding running non-graphics applications on GPUs, there’s still very little outside of games that makes more than passing use of a desktop or laptop GPU. More to the point, the number of games demanding a really high-end GPU that are actually worth playing isn’t merely a small number. It’s zero.

Put it all together and you have a terminal mismatch between the cost and complexity of GPUs and their real-world utility. In truth, I’ve felt this way for some time. But it’s the apparent emergence of a radical alternative to established 3D rendering technologies that really brings home how bloated and ludicrous graphics chips have become.

This alleged revolution in rendering comes from a small Australian software startup known as Unlimited Detail. It’s not actually brand spanking new, having been in development for a year or three. But thanks to the random nature of web-based content aggregators, Unlimited Detail was lifted from obscurity recently in a flurry of YouTube-powered publicity.

Anyway, as far as I could tell the basics of this new rendering technology involve ditching polygons in favour of atomic points in 3D space. The claimed result is quite literally unlimited geometric detail. Oh, and the whole thing runs in software at smooth framerates on a conventional PC processor. The GPU doesn’t get a look in until it’s time to spit out the final 2D images.

You hardly need me to point out it all seems too good to be true. So, there was nothing for it other than to go straight to the source and speak to the guys at Unlimited Detail. The technical brains are provided by Bruce Dell, a former supermarket manager, while the business nous comes courtesy of Greg Douglas, a games insider formerly of developers Auran.

The idea of using atoms or points is not new, of course. The really clever bit in UD is the 3D search algorithm developed by Dell. The precise details are UD’s big secret. But according to Dell, “The algorithm takes point cloud data and files it in a certain way so that it can be quickly sorted and accessed.”

When the algorithm searches for points, it doesn’t do so indiscriminately. Instead, it only pulls up a single point for each on-screen pixel being rendered. “We only grab the atoms we need for each pixel, we don’t touch the others,” explains Dell. In other words, the workload depends on screen resolution, not the underlying geometric detail of the scene being rendered. Thus, an impression of unlimited geometry is created.

The UD guys claim the algorithm is so efficient it runs in real-time in a single thread on just one core of a conventional PC processor. Apparently, it will even scale down to simple CPUs in mobile devices.

So far, the only hard evidence for these incredible claims takes the form of a few pre-recorded videos of dubious quality. However, having spoken to the UD pair, I’m happy to confirm they’re not only incredibly passionate, but strike me as completely genuine. It’s potentially extremely exciting stuff.

Still, even if UD works exactly as advertised, the established players in graphics are hardly going to embrace a technology that instantly renders several decades and billions of dollars of investment obsolete overnight. You have to assume Nvidia, and to a lesser extent AMD, will resist the idea strongly. But if Unlimited Detail’s technology gains any traction at all, GPUs really will look sillier than ever.

The blossoming of multimedia content on the Internet in recent years has
revolutionised personal interactions, business communications, and
other online services. But for millions of Internet users with sensory
disabilities, many of the communication tools remain frustratingly out
of their reach.

In a press release, Mr Arnoud van Wijk, Disability Projects Coordinator for the Internet
Society (ISOC), who was born deaf, knows only too well the frustration
Internet users with a disability experience from many current Internet
services.

“During the past few years, the use of the Internet as a modern
replacement for telephony has accelerated,” said Mr van Wijk. “The
ability to include more media in calls provides an excellent
opportunity to include people with disabilities in online
conversational services. But too often discriminatory voice telephony
services are simply re-created.”

With this motivation, Mr van Wijk and other researchers have
documented a technique for “real-time text”; combining existing
Internet Engineering Task Force (IETF) standards to enable text
streaming over Internet Protocol networks.

The technique uses Internet telephony protocols to ensure
compatibility with voice, video, and other multimedia services on the
Internet. It allows text to be sent and received on a character by
character basis, with each character sent and displayed immediately
once typed, giving text the same conversational character as voice
communication.

According to Mr van Wijk, “Internet Telephony is rapidly becoming a
major way of staying in touch. But it breaks the traditional text
telephone, which deaf and hard of hearing people used in the past to
call each other. The real-time text technique addresses this problem
and can be integrated with Internet telephony.”

Along with fellow technologist Guido Gybels, Director of New
Technologies at RNID (UK), and with contributions from other experts
in communication and accessibility for people with disabilities, Mr
van Wijk edited and co-authored ‘Framework for Real-Time Text over IP
Using the Session Initiation Protocol (SIP)’, which the IETF has just
published as an informational document in its ‘Request for Comment’
series as RFC 5194.

To further progress work in this field, this week sees the launch of
the ‘Real-Time Text task force’ (R3TF), an informal forum for
engineers, motivated individuals, experts, companies and
organisations. The R3TF has received incubation support from ISOC, as
part of its “Enabling Access” initiative, under which ISOC promotes a
diverse range of projects aimed at breaking down the barriers to
Internet access.

Michael Burks, Chairman, and Cynthia Waddell, Vice Chairman of ISOC’s
Disability & Special Needs Chapter, welcome the announcement of the
new task force.

“Accessibility for persons with disabilities is critical and must be
maintained in the coming convergence,” said Ms Waddell, an
Accessibility Expert to the International Telecommunication Union
(ITU), who is hard of hearing herself. “But it is worth pointing out
that, like many disability projects, this effort has the potential to
provide more options and greater usability for all users in many
situations.”

President Levy Mwanawasa has with immediate effect dropped and recalled Mbita Chitala as Zambia ambassador to Libya.

According to the Times of Zambia Newspapers, the Presidents action was prompted by Mr Chitala’s article in which he was advocating for policies which he termed as being contrary to the Government position on the African Union.

Mr Chitala was not given any authority by the Zambian government to write what he wrote on in The Tripoli Post.

“The article has caused untold embarrassment to his excellency the President and the Government of Zambia and a Foreign minister of a country whose leader was described in very unkind words has intimated that he will send a note of protest to the Zambian Government.”

A search on the internet found an opinion piece on the link below which Mr Chitala wrote.

Opinion: The Federal Union of African States Must be Established Now
By Ambassador Mbita Chitala
26/01/2008 16:29:00
Introduction

This presentation addresses the subject of the historical necessity and inevitability of the federated African state. The central argument of the article is that continental integration and empowerment can only succeed if the coordination of efforts is at a continental level through first, the formation of one all African State, that is, by way of a political decision and that economic integration shall only be complementary.

This article does not discuss the benefits that will be derived from Africa’s political integration (insure peace keeping, combat disease, environmental concerns, poverty, corruption, oversee good governance, equi-distribute Africa’s wealth) as this is already a settled argument nor does it discuss the method and road map for achieving this historical inevitability as this is a detail to be designed by professional managers.

This write up is aimed at imploring African leaders to make the political decision and establish the united one African state as they meet at Addis Ababa, Ethiopia on 31 January, 2008.

Status of Africa’s Unity

Post independence Africa presents a divided and balkanized states, weak, and for more than four decades has continued to be a play ground for unabated abuse, exploitation and oppression of its peoples by other more organized political regions as exemplified by the hegemonic control the Europeans and Americans still hold on Africa.

Africa’s age old yearnings for political and economic integration have been thwarted, of course variously explained by many factors and interest opinions. These factors include the influence of self-seeking, narrow-minded nationalist African leaders who have continued to opt for personal glory and fame at the expense of the larger Africa using the legalistic excuse of sovereignty, the influence of the vestiges of colonial aberrations and neo-colonial psyches and dominion where Africa in the international division of labour has continued to play the role as a supplier of raw materials and net importer of manufactured commodities which in the process condemns Africa to continue being exploited by way of unequal exchange.

In the area of consciousness, cultural imperialism has been ensuring that Africa is divided between two blocs – Anglophone and Francophone – and this division has been sustained by the former colonial powers variously such as establishing institutions like the British Commonwealth with their British Council, and the French Francophone with their Alliance Francais.

These have continued to sew divisions among Africans by false ideologies such as the Christian-Moslem dichotomy, the Arab-African dichotomy and the ethnicity or tribal ideologies that are used to divide and weaken Africans. With globalization, Africa has further deepened its integration to the global finance capital from a weak stand point where it cannot get an equal share of the benefits of globalization.

African countries have attempted to unite the many small post colonial social formations to address this issue of poverty, underdevelopment and insecurity of Africa but often have fallen short because of the above reasons or because they used unsustainable unworkable methods such as desiring to have economic integration before political unity.

The most notable attempt was the Abuja Treaty – Regulation CM/464 of the 26th OAU Council of Ministers who wanted to create five regional communities who would play the role of the future continental common market. The recommendation was based on the realization that integrating 53 differently ruled African States would be unsustainable because of the unripe consciousness, the influence of geography, ecosystems and operational precedence. This attempt failed and more regional communities continued being formed.

In pre-Abuja Treaty, there were 8 Regional Economic Communities (RECs) including SACU, MRU, ECOWAS, CEPAL, ECCAS, IOC, IGAD and UMA. In post Abuja Treaty, more RECs have been established. These include SADC, UEMOA, CEMAC, COMESA, CEN-SAD, EAC.

All these have been set up in spite of duplication of programmes and their multiplicity, cross cutting membership and inefficiencies have compromised African integration. An attempt towards rationalizing them has failed because of lack of political will and resentment and opposition by the established public service supported by entrenched rules and contracts.

It is unacceptable for African leaders to continue procrastinating or making lame selfish excuses of going to consult their peoples and so on such as has been the case in the last ten years. There is no need for these countries to hold referendums as Muammar Gaddaffi challenged his colleagues at the Accra Summit.

The opposition to integration that was exhibited by Kenya, Nigeria and South Africa in Accra is regrettable as it was based on the false assumption that these three countries would on their own develop to be sub imperialist powers.

It is gratifying that Liberia, Senegal, Ethiopia, Chad and Libya came strongly for immediate political unity. The rest remained look warm. It is no wonder the Africans in South Africa and Kenya have already shown their leaders what they think of their acts in Accra. What is required as the first act is to agree on political integration by establishing the Federated Union of African States.

This was the consensus that was reached after the transformation of the OAU into the AU on 9th September, 1999 at Sirte in Libya where all African Leaders committed themselves to the establishment of the United States of Africa.
“Those who want to move on a snails pace or are opposed to Africa’s political integration should be left out for now. Their own nationals will deal with them in due course and compel them to join the bigger good – the Federated United States of Africa.”

It was therefore amazing at the meeting in Accra, Ghana in July, 2007 that about 50% of African countries continued to give lame excuses at delaying this historical necessity which has as a result continued the tendency of the marginalization of the continent in global affairs as well as deepened the underdevelopment of its people.

As the leaders go to meet again in Addis Ababa on January, 31st, 2008, all progressive Africans are hoping that the final solution to African Unity and integration will be found. Now, Africa has entered the globalization process from a point of weakness.

New constraints have emerged, particularly with timeframes imposed by initiatives such as the EU, the WTO, China and so on. It is therefore imperative that a new momentum and initiative within a better structured continental framework with improved follow up on both the political leadership and rationalization and implementation of one African economic set up be launched.

Political Integration First, then Economic Integration

Former Zambian President Dr Kenneth Kaunda and former Algerian President Ben Bela are the only two Africans still living who can attest from first hand account the ideals yearned by Africa’s founding fathers of a strong and independent one African State that was championed by African heroes such as Kwame Nkrumah, Julius Neyere, Patrice Lumumba, Toure, Gamal Abdul Nasser, Emperor Haile Sellassie, Jomo Kenyatta and other African patriots.

These ideals have been taken up by a few progressive African leaders notably Muammar Gaddafi of Libya, and the Senegalese President Wade who have been trying to persuade fellow African leaders to move forward on this African integration process. In the last ten years, Libya has had to spend a lot of money and effort trying to have the project realized.

Muammar Gaddafi and the leaders of this progressive tendency have been opposed by a conservative fringe whose chief response has been that they are not ready or they must first consult their people or that they are afraid of losing their sovereignty or simply remain non committal. This bloc has been lukewarm and has chosen the road towards Africa’s integration by first strengthening regional economic groupings and assumed that the integration process will ripen on its own. The logic of this route is to further divide Africa. This is the route championed by African colonial masters now united as the European Union.

It has been argued by some African leaders and supported by neo colonial think tanks at the secretariats of the Economic Commission for Africa, the African Union and the United Nations that the challenges Africa faces is for the Regional Economic Communities ( RECs) to harmonize their programmes so as to attain convergence and ultimately the African Economic Community.

Even though the REC’s are not among the organs of the African Union (AU), it has been argued by these think tanks that they can still be used as building blocks of the African Union government as they were anticipated to be for the African Economic Community under the Abuja Treaty.

It has been obvious from all and sundry that such an approach would forever thwart the advancement of the African confederation and would play in the hands of Africa’s enemies who want to continue subjecting the continent to age old disadvantages such as imperialist exploitation and marginalization of the Africans in global affairs.

To the progressive Africans, it must be obvious that this incremental approach is not only unsustainable but must be overthrown and be replaced by a Nkrumah/Nasser and currently Gaddafi/Wade approach that argues for “seek ye the political kingdom first, and all would follow”.

The argument that Africa should first rationalize and harmonize the more than fourteen (14) regional economic cooperation groupings and use them as the basis for advancing to Federal Africa is a view point that is against historical experience.

In practice, it is utter mechanistic nonsense and is a road to continued balkanization of the continent, weakening Africa and ensuring that it continues to be a market for imperialist capital. Only political unity can advance the economic integration agenda and break the suffocating tentacles of imperialism which have for the last 200 years constrained Africa’s advancement.

The only Question at Addis Ababa and Africa’s Prayer

It is important that Africans, as they meet at Addis Ababa on 31st January, 2008 realize that unless they create political space in the sense of an all Africa Federal State, all what Africa has always aspired for will be in vain. We will have to wait for another generation to attempt at unity again. What a waste of ten years investment of our time and resources!

At the Accra Summit of the African Union in July, 2007, the decision to establish the federated State of Africa was postponed for six months to allow for further national consultations. About 50% of African States mainly in the CEN-SAD group were for the immediate establishment of the United States of Africa. Another group mainly from the SADC area was lukewarm to the ideal and politely opposed the immediate creation of the African Union State.

They regressed to the outdated Abuja Treaty argument of basing unity on the gradual development of regional groupings.

Today, Africa faces the challenges that Nkrumah and his colleagues faced at the beginning of this argument which resulted in the creation of two blocs – the Casablanca and Monrovia blocs among African leaders. The question then was principally how to advance the decolonization of Africa.

The bloc led by Nkrumah, Nasser, Nyerere, Haile Sellasie, Ben Bella, Kaunda, Toure, Lumumba and others won the day against the African reactionaries who advocated for some regulated independence. Today, there are about 53 politically independent African States – most of them are weak and are simply outposts of imperialist exploitation and subjugation.

It is necessary, nay, a historical inevitability that Africa must first address and achieve political unity under one State for any meaningful progress to be made towards playing any equal role in the global community. The harmonization and rationalization of the REC’s will also follow naturally as politics will lead.

The argument which has been advanced by some of our leaders that political unity will only be reached if and when all African States accede to the ideal by way of consensus is obviously, not a useful position. For practical reasons, this 100% unanimity is utopian as some African States are under the hegemony of imperialism or are simply reactionary and/or will never be allowed by their imperialist masters to accede to Africa’s political integration. These countries should not be allowed to hold progress of other Africans. They should no longer delay this movement towards Africa’s emancipation and unity.

Those who want to move on a snails pace or are opposed to Africa’s political integration should be left out for now. Their own nationals will deal with them in due course and compel them to join the bigger good – the Federated United States of Africa.
