IanCutress Posted November 21, 2012 Share Posted November 21, 2012 (edited) Got my head around some C++ AMP at the weekend and wrote a benchmark for DX11 GPUs that probes some of the computational aspects in grid solvers. Each stage lasts for 30 seconds - CPU score is designed to be less than 5% of the overall grade, but as always having a fast CPU helps keep the GPU fed. AMD doesn't fair too well, but that's more a weakness of the DX11 API with C++ AMP for this sort of thing. Download below and feel free to test! // System Compute // (c) 2012 Ian Cutress // // System Compute is a benchmark designed to stress the CPU and AMP device of the system // // Changelog // // v0.4 : Added CPU detection // v0.3 : Added AMP MatMul // v0.2 : Fixed Score calculation // : Added 2D IMP CPU // : Made it look nicer // v0.1 : Initial Build // : 2D-CPU // : 3D-CPU // : 2D-AMP // : 3D-AMP Still need to add result verification tools.

sumonpathak Posted November 21, 2012 Share Posted November 21, 2012 anyway to get the source code? i have a buddy who is interested in coding part of benchmarking..so was thinking if anyway i can get him to help out. Quote Link to comment Share on other sites More sharing options...
IanCutress Posted November 21, 2012 Author Share Posted November 21, 2012 Code is not public, same reason FM doesn't make its code public I suggest getting a book or two ofc. I get a portion of my computational code from back when I did my PhD, as such it's based on real life problems. As long as your buddy is proficient in C++, have a look at n-body simulations. Those are always interesting and taxing, or black-scholes for finance. It's a case of picking up an algorithm and having a go. A strong background in mathematics always helps, especially when writing optimised code :thumb: Quote Link to comment Share on other sites More sharing options...
sumonpathak Posted November 21, 2012 Share Posted November 21, 2012 actually i was more interested on why AMD card is not fairing well...wanted to look into that part Quote Link to comment Share on other sites More sharing options...
sumonpathak Posted November 21, 2012 Share Posted November 21, 2012 anyway...i will run this on a few cards and report back... Quote Link to comment Share on other sites More sharing options...
IanCutress Posted November 23, 2012 Author Share Posted November 23, 2012 actually i was more interested on why AMD card is not fairing well...wanted to look into that part AMD GPUs fair OK, but a big driver of single GPU perf is single core speed as everyone knows The Trinity A10-5800K CPUs are about 35% off an Ivy i3-3225 at stock, hence the big decrease. It just so happens that PCIe speed is all critical as well. PCIe 3 > PCIe 2, and as much BCLK as you can fire at it also seems to work. http://www.overclock.net/t/1329409/i-made-a-benchmark-systemcompute-v0-4/0_100#post_18651666 is where the main thread is Quote Link to comment Share on other sites More sharing options...
