oscarbg Posted August 27, 2009 Share Posted August 27, 2009 Please change __kernel void vectorAdd( __global const float * a, __global const float * b, __global float * c) { // Vector element index int loop; int test1; int nIndex = get_global_id(0); for (loop=1; loop< 1000; loop++) { c[nIndex] = a[nIndex] + b[nIndex]; c[nIndex] = c[nIndex] * (a[nIndex] + b[nIndex]); c[nIndex] = c[nIndex] * (a[nIndex] / 2.0 ); } } to use float4 sould use vector units on CPU (SSE) and ATI (improve perf 4x) also should imporve meory fetches on ATI GPUs (optimized for float4).. If you are brave enough use float8 (hey it shold be ready for Sandy Bridge AVX extensions) or more brave enough to float16 (hey ready for Larrabe).. and loop 250 times: also loop=1; loop< 1000; only exectues 1000-1 times __kernel void vectorAdd( __global const float4 * a, __global const float4 * b, __global float4 * c) { // Vector element index int loop; int test1; int nIndex = get_global_id(0); for (loop=0; loop< 250; loop++) { c[nIndex] = a[nIndex] + b[nIndex]; c[nIndex] = c[nIndex] * (a[nIndex] + b[nIndex]); c[nIndex] = c[nIndex] * (a[nIndex] / 2.0 ); } } The DL link is at the end of that posting. - Mac OS X 10.6 - Snow Leopard ONLY ! (will not run in 10.5 / 10.4....) UPDATED OpenCL_BENCH to V025 V025 changes - fixed bug with showing same cards twice in system > 2 gnu (hopefully fixed: ) - ATI compatible , reduced gnu code in size for an fix of the ATI problems with this bench - therefor the time results cant be 100% compared to old versions - faster on CPU+GPU GPU time new = GPU time old / 3,3 CPU time new = CPU time old / 2,5 So GPU part shows more advantages vs CPU with that version - cleaned up the informations for better readability - GPUs now shown + benched before CPU - added error handling code SOURCE CODE available - help to get ATI running well / make Bench much better http://freenet-homepage.de/amichalak/OpenCL2_SRC.zip OPENCL - Good to know : - OpenCL is an API for universal GPU(CPU) computing - main difference to CUDA / ATI STEAM is: both only working with their "own" gpu. an CUDA (NV) app like badaboom(h264 on GPU) cant work on an ATI gpu and vice versa - OpenCL is universal means: - Xcode / GCC compiles an code which includes the source (in C as an string) for the gpu programm that c source is , different to CUDA/ATI STEAM , is compiled later by OpenCL at runtime ! So same App can run on complete different gpus and also , without/less codechange om CPU if no OpemCL gpu (newer ones) is found The source (example below) for the gpu programm will be really compiled at runtime, not only interpreted. So little differences between run of my bench may happen because of that compile on the run Results posted: Conclusion until now: The faster the GPU(exact the Units/programmpart) and slower the CPU the more useful is OpenCL. NEW V025 test results ! ATIs (no freezes of the bench anymore , ATI 4870 works now): Number of OpenCL devices found: 3 OpenCL Device # 0 = Radeon HD 4870 Device 0 is an: GPU with max. 750 MHz and 4 units/cores // 4 cores are wrong !!! // Now computing - please be patient.... time used: 4.126 seconds by mtonkol Number of OpenCL devices found: 2 OpenCL Device # 0 = Radeon HD 4870 Device 0 is an: GPU with max. 750 MHz and 4 units/cores time used: 3.997 seconds At least with actual drivers and my benchmark ATI benches are useless. Seems to be that either OpenCL isnt sooo universal (same code run on all GPUs optimized) or bugs in ATI OpenCL part. Maybe some OpenCL PRAGMA settings must set for ATI to get better performance.

mitch_de Posted August 27, 2009 Author Share Posted August 27, 2009 Thanks ! Will do that soon and upload V030. EDIT: First runs show that float4 (in gpu source & main app) makes gpu part run significant slower(on my 9600). Insted 10 times faster than CPU with float4 it runs 2 times slower than CPU. Also i have seen that AMD ( http://ati.amd.com/technology/streamcomput...tro_opencl.html ) also uses float and not float4 in their own example. I will now change the code back to float, but remove the loop so that the source looks like amd example ; Link to comment Share on other sites More sharing options...

I will now change the code back to float, but remove the loop so that the source looks like amd example ; well, for one part, this is just a simple kernel, no "how you should do stuff example". float4 should be better on all devices if done correctly (intel sse can do 128-bit/float4 operations, ati gpus have those weird 5D vectors? and nvidia gpus are better with that too). oh, and you shouldn't do "for (loop=1; loop< 1000; loop++)" inside a kernel, this misses the whole point of opencl. would be better to do that on the outside when calling the kernel. you are also timing the buffer readback (slow!) which isn't such a good idea when you just want to know the raw cpu/gpu power. what also puzzles me is that some core i7 folks get 4 compute units and others get 8 ... any idea why? disabled hyper-threading? mainboard/dsdt incompatibility? differences in the x86 and x64 drivers?

mitch_de Posted August 28, 2009 Author Share Posted August 28, 2009 I cleaned up gpu code - without loop, only verctor add line, much smaller memory transfers to/from GPU, time listed in ms not seconds, removed valid checking - and upload an new version soon. Also an float2 / float4 version will be uloaded. But i dont think that this will change anything of the ATI problems witch the bench! I also got an information of an ATI dev, that ATI´s OpenCL implementation and also HW is a bit different to Nvidias. So at least at these days OpenCL may be not so universal and some fuctions NV supports ATI supports with bad speed and vice versa. Nvidia looks like thats been much earlier developed OpenCL / dev their HW for CUDA functions so has some advantages (until ATI updated OpenCL driver / OpenCL on the fly compiler parts).
