Benchmark for speed-up comparison of GPU/FPGA etc.

QuoteThis development is a wave equation with period of 10 years. It's the age-old question: centralised or decentralised? Ivan Sutherland wrote an article on this in 1969. Not much has changedLOL good point

Benchmark for speed-up comparison of GPU/FPGA etc.

<r>Sorry I missed this threadI work in HPC oil + gas and as I say elsewhere coprocessing is all the rage and will only continue to increase in popularity ie., CPU + x where x might be GPU, FPGA and someday soon a quantum computer (or some other piece of esoterica). When I say coprocessing I mean x b...

GPU, FPGA, OpenMP, etc. which one should I choose?

I've used it for a few things, appears to be stable and is very easy to read/use, it's a header library

MATLAB and GPUs thru Jacket and CUDA

au contraire Just don't be transferring data too much, unless it's asynchronous and hidden behind the cost of calculation. I'll get to my homework assignment in the other thread eventually

MATLAB and GPUs thru Jacket and CUDA

<t>I've used and would recommend Jacket, although you can hack Matlab/Octave + CUDA yourself, I give details here. I had an interesting discussion at the same blog post with someone who's done this more extensively, their work is here. Interested parties might also want to check out GPULib.BTW wills...

ok lets slowly do this; but first here's our homework reading assignmentmj I still have plans to get our (metwally et al) barrier options project I mention elsewhere integrated into kooderive

the auto has been put off till retirement If you post a little code for your PDE we could slowly walk through a port to CUDA?

lolbut I haven't tried that problem yet! you could extrapolate from examples I give hereI'd expect about 10x over nehalemWhen I finish the FPGA finance (side) project with Outrun, I'll give that a go

GPU, FPGA, OpenMP, etc. which one should I choose?

<t>index coupling is very doable in GPU, one needs to use halos to pass data between threads. So shared memory and some thread synchronization is necessary, but not prohibitive.I'm porting some reservoir simulation code to CUDA, mostly FDM/FEM and associated solvers. Work share constructs make decom...

Thanks very much for the link; I had seen it a while ago, I certainly need to incorporate your improvements.I will keep you informed, I appreciate the expert input!

<t>QuoteMy philosophy so far has been very step based: do the first thing for every path, then the second thing for every path, and so on. This does mean that one has to store data in global memory but I haven't found this a huge problem. I have also found texturesuseful for reducing loss of time du...

true, so long as reads and/or writes are coalesced I suppose there isn't much to be gained by keeping values in device memory for single use. I am curious though about scaling to higher dimensions, I suppose I'll cross that bridge when I get to it.
