Larger problem give more precise measurements on average.įeel free to use and share it if you find it useful. Giles, Monte Carlo evaluation of sensitivities. The performance is measured with varying numbers of Monte-Carlo paths (from 64K to 2,048K). AMD has used LuxMark as one of the 5 GPU computing benchmarks to present the HD7970 and Apple used. If you are planning to use a weaker GPU you might want to decrease it. This benchmark uses a portfolio of 15 swaptions with maturities between 4 and 40 years and 80 forward rates (and hence 80 delta Greeks). LuxMark is a OpenCL cross-platform benchmark tool. The problem size that can be adjusted is the number of workgroups (I named it ‘Blocks’ as in CUDA). So far I’ve run it on AMD, Intel and NVIDIA platforms and several ATI/NVIDIA GPUs + Intel Sandy Bridge/Ivy Bridge CPUs. This tutorial explains how to get started with OpenCL and how to make a small OpenCL program that will compute the sum of two lists in parallel. This option supports environment variables. loader null (string, null) Optional path to OpenCL-ICD-Loader. How fast is your OpenCL Discover which OpenCL benchmarks and tools are available to help you evaluate your OpenCL performance and test your implementation. cache true (boolean) Enable or disable OpenCL disk cache for compiled code. enabled false (boolean) Enable or disable OpenCL mining backend. Getting started with OpenCL and GPU Computing by Erik Smistad. XMRig Config File OpenCL This page is not finished yet. The GPU driver crashes sometimes because of that, it would be good to avoid that.Īnd test it. OpenCL is an open standard maintained by the non-profit technology consortium Khronos Group. Is there any way of getting information about that in advance - before actually running a kernel? mobile ones) I get an error indicating that it is out of the resources. The second one is related to OpenCL - Sometimes when I run the program on weaker GPUs (i.e. So here’s my first question - has anyone succeeded having OpenCL capable GeForce/TESLA and Radeon in Linux? I’ve noticed that the drivers do something with the kernel, hence the problem. See how your system performs with this suite using the Phoronix Test Suite.Its as easy as running the phoronix-test-suite benchmark opencl command. I programmed it under Windows as I couldn’t make NVIDIA and ATI GPUs work together in Linux. It is based on a simple FMAD code to maximize the throughput. I wanted to check how the datatypes affect the performance.īasically I just ported my older code from CUDA in order to compare the results as I am considering OpenCL as an alternative. It's similar to a man entry for the command. amdgpu-install -h to learn about how the script works fundamentally. For a complete overview on its usage, you can use the command. amdgpu-install -opencllegacy,rocr -headless -no-dkms. I wrote a simple application for my purposes to measure the peak FLOP/s of a device in OpenCL. Now, I'm going to install OpenCL both for legacy and newer GPUs.
