Comment: The future of Supercomputing? (Score 1) 1

by JohnConnor (#36160522) Attached to: Nvidia launches fastest "parallel processor"

The popularity of these GPUs baffles me. They are hard to program and very limited in what they can do, not to mention the horrible transfers to main memory, yet because there is no other foreseeable technology coming in the next 5 years or so they are becoming the standard for massively parallel programming on a budget. Any university and its dog has GPU projects, with wild performance claims, usually measuring a code they spend years optimizing for the GPU against the original code running un-optimized on one CPU thread. Yet in the real world there are very few applications of the GPU. The memory transfer bottleneck amplifies Amdahl's law. I work in an mission-critical supercomputing center and it will be years before we adopt the GPUs because of the manpower required to convert existing code, the uncertainty of the future of the technology, the quasi vendor lock-in situation that we have now with NVidia, and the fact that vendor support is not yet where it should be. Yet I am watching this technology being slowly adopted by everyone for lack of a better alternative. Thinking about it, it is pretty sad times that we live in term of supercomuting. Don't believe me? Ask the vendors what exciting new technology they have coming. They don't have any.

angry tapir writes "Nvidia has announced the Tesla M2090 graphics processor, which the company calls the world's fastest "parallel processor" for high-performance computing. The M2090 is a graphics processing unit that has 512 cores and is able to perform specific math and scientific calculations up to 30 percent faster than its predecessor, the Tesla M2070 GPU, which has 448 cores. The M2090 can deliver peak performance of around 1330 gigaflops, according to the company."

Nine features we may see in Ubuntu 11.10 'Oneiric -> 1

Submitted by splitenz
splitenz writes "Canonical's Ubuntu 11.04 "Natty Narwhal" may still be occupying much of the Linux world's attention, but at last week's Ubuntu Developer Summit in Budapest, the next version of the free and open source Linux distribution began to take form.

A number of decisions were reportedly made about Ubuntu 11.10, or "Oneiric Ocelot," at the conference, while numerous other questions are still being debated.

Ready for a very early look at Oneiric Ocelot? Here's a roundup of what's been reported so far."

Your operating system is Linux, not Ubuntu. You operating system is not worrying at all about how you should be buying mp3s, you can rest assure. Ubuntu is much more than an operating system, it's also a whole set of applications, a way to integrate them together and extra services as well. I doubt that you only want basic OS functionality, but if you do just install the server version of Ubuntu and your problem is solved.

It's not surprising at all that Oracle would shut down a free competing product to its unbreakable Linux. In fact it would be crazy for them to allow internal competition between two OSes to happen. What I am really disappointed about is the fact that *open*solaris was not really open and that now it will die. That's what sucks about the various half-assed open-source licenses and practices of former Sun. Had openSolaris been a complete open-source prject, not dependent on binary blobs, the closing of solaris itself would not be such a problem.

Doom-Like Video Surveillance For Ports In Development 56

from the hurt-me-plenty dept.
oranghutan writes "A research and development group down under is working to develop an advanced video surveillance system for ports around the world that uses video superimposed onto a 3D map. With 16-megapixel high-definition cameras on a distributed (cabled) network and a proprietary system written in a variety of languages (C++, Python, SQL, etc.), the group from NICTA is aiming to allow security teams at the Port of Brisbane — which is 110km long — to monitor shipping movements, cargo and people. By scrolling along a 3D map, the security teams can click on a location and then get a real-time video feed superimposed onto the map. Authorities from around the world with the right permissions can then access the same system. The main difference from regular surveillance systems is the ability to switch views without having to know camera numbers/locations and the one screen view."

Infinity Ward Fights Against Modern Warfare 2 Cheaters 203

Posted by Soulskill
from the be-careful-they-cheat dept.
Faithbleed writes "IW's Robert Bowling reports on his twitter account that Infinity Ward is giving 2,500 Modern Warfare 2 cheaters the boot. The news comes as the war between IW and MW2's fans rages over the decision to go with IWnet hosting instead of dedicated servers. Unhappy players were quick to come up with hacks that would allow their own servers and various other changes." Despite the dedicated-server complaints, Modern Warfare 2 has sold ridiculously well.
