Reading up on the announcement of the new "Titan" NVIDIA series GPU with it's potential 4.5 teraflops performance, a card that will retail for about £850 here in the UK, I was wondering if the BOINC client supports this card and the Cuda Core architecture?
I could not find anything in the forums, but the card has only recently been announced. Screaming fast. Whisper quiet. Despite being ten times more powerful than its predecessor, the Titan supercomputer takes up the same amount of space and uses the same amount of power. Only GTX TITAN brings this rare combination of raw power and incredible efficiency to PC gaming. NVIDIA® Kepler™ architecture gives you 2,688 NVIDIA CUDA® cores and 4.5 teraflops of gaming horsepower. Plus, GTX TITAN delivers a 384-bit memory interface running at a blazing fast 6 Gbps for an amazing 288 GB/s of memory bandwidth—enough power to handle even the most extreme high-resolution games. The card also comes with 6GB of DDR3 RAM. As I run a few CPU cores in older machines in my garage - all given over to BOINC - would I not be better off aiming at re-deploying older Gen. Graphics cards? The BOINC client is also a bit vague on whether GPUs are in use or not. the only thing I have ever found is the "enable GPU" checkbox. For example, my old single core AMD CPU also has an AMD dedicated graphics card - but I have no idea whether the graphics card is being used by BOINC or if it is idle. |

Welcome to the forums
WCG does not support CUDA utilizing sciences at this time, but BOINC does detect this and runs well with it at other pprojects. If your GPU cards support OpenCL v 1.1 or higher [a coding language not exclusive to NVidia], then good chance is you could run HCC1 on it, the only GPU enabled WCG science.

For the price, I'd take this one and it does work here.

Thanks for the feedback on the GPU questions - I will look into this further.
Is there any way to know what the client is doing reagrding use of a GPU or not? |

Tom's Hardware just did 2 articles with compute benchmarks including with CL. The Titan was compared to the 690 and 7970 as well. Basically the 7970 still outperforms the Titan in CL, however the Titan has better acoustics. It is a good read. I just focused the compute portion.

Also, according to both Tom's and AnandTech articles the OpenCL support in Titan is not fully baked in the drivers. With new drivers the numbers can change. In double precision (with double precision mode enabled) the Titan beat the 7970.

The first several lines in the message tab of BOINC 6.10.58 will tell you whether or not your GPU is properly detected by BOINC. The only GPU work currently here at WCG is HCC. If your BOINC client has downloaded HCC GPU work units the application name will in the tasks tab will be appended with (nvida_hcc1) or (ATI) respectively. You will need to check the "allow work for my graphics card" in your WCG device profile in order to receive GPU work.

Since the Titan costs more than two 7970s, does it beat both of them?  ---------------------------------------- [Edit 1 times, last edit by BladeD at Feb 24, 2013 5:09:17 PM] |

Hey, but you get a solid CUDA for that as bonus [lock in] ;)

For the price, I'd take this one and it does work here. This, or maybe 2 7970s. Both have advantatges and disadvantages, but both are comparable in price, come with GDDR5 instead of DDR3, and outperform the nvidia in the reviews that I've seen. I also think that amd has positioned themselves better in the GPGPU market with a (seemingly) bigger focus on OpenCl and support for c++ amp and whatnot. You can tell if a WU is using the GPU by seeing what's allocated to the WU in the Boinc client. The number of cpus and gpus will display next to the WU. The problem you might run into using "older hardware" is obviously the hardware itself (power demands, pcie lanes, cooling, case size, etc). There's also a point of deminishing returns where you might not have enough compute power to process the CPU portion of each WU at a rate that will keep your card busy. It takes me 5 cores @ 2.6ghz and 20 simultaneous WUs to keep my 7950 continuously busy:) My two cents.. Edit: My TL;DR; recommendation is not to necessarily run older generation gards, but lower end cards on older hardware. [Edit 2 times, last edit by Former Member at Feb 24, 2013 7:37:28 PM] |
