GROMACS SYCL for Intel GPU

GROMACS version: 2023.2
GROMACS modification: Yes/No
Hi,
I’ve just install GROMACS with SYCL enabled, however, it seems like GROMACS cannot detect my GPU. My GPU is Intel Iris Xe Graphics, I’m using Ubuntu 22.04, CMake 3.27.4, and Intel oneAPI DPC++/C++ Compiler with MKL library 2023.2 for SYCL. Here it says SYCL is enabled:

gmx mdrun --version

But when i run a command in MD simulation, it appears as:

Program: gmx mdrun, version 2023.2
Source file: src/gromacs/taskassignment/findallgputasks.cpp (line 85)

Fatal error:
Cannot run short-ranged nonbonded interactions on a GPU because no GPU is
detected.

Here is the CMake flags i used and the running details if it helps:

I recognize that in the cmake running, it found CPU but didn’t mention about GPU, I don’t know if it’s normally not mentioned in SYCL building or it is a fault.

Please help me sort it out as soon as possible, I really need GPU acceleration for my works. Thanks in advance.

Best regards.

Hi!

Could you please show the output of sycl-ls? From the data that you showed, the GROMACS seems to be compiled correctly, so there are probably some issues with drivers.

I recognize that in the cmake running, it found CPU but didn’t mention about GPU, I don’t know if it’s normally not mentioned in SYCL building or it is a fault.

CMake does not perform GPU detection, so nothing wrong with your output.

Sidenote: GROMACS does not use GMX_SYCL_DEVICE and GMX_SYCL variables (not sure where have you found them); there is no harm specifying them, but they are ignored (and GROMACS correctly defaults to settings for consumer-grade Intel GPUs).

Hi,
Here is my output of sycl-ls:
[opencl:acc:0] Intel(R) FPGA Emulation Platform for OpenCL™, Intel(R) FPGA Emulation Device 1.2 [2023.16.7.0.21_160000]
[opencl:cpu:1] Intel(R) OpenCL, 12th Gen Intel(R) Core™ i5-1240P 3.0 [2023.16.7.0.21_160000]

I can’t see my GPU listed so that’s maybe the reason why, may you please pointing out for me where the error occured?

Oh, and thank you for your “Sidenote”, I had some troubles before, I asked ChatGPT and it sucked LOL, it showed me these GMX_SYCL_DEVICE and GMX_SYCL variables, and surely didn’t work at all, but I solved that so it’s not the case today.

Since it’s a laptop, I assume that the GPU works for graphics at least, right?

It might be worth trying to install the latest Intel Compute Runtime: Release 23.26.26690.22 · intel/compute-runtime · GitHub, if you have not already.

I’ve just installed the latest Intel Compute Runtime as you said. However, after that I tried to install GROMACS with SYCL again but nothing ever changed. During my make command running, I saw a warning, and I wondered if it may cause troubles in detecting GPU, though I continue to install it as normal.

Is sycl-ls now showing GPU or not?

  • If sycl-ls is still not detecting the GPU, there is no reason to try reinstalling GROMACS until it does. sycl-ls is Intel’s own tool from the oneAPI toolkit. If it cannot detect the GPU, neither can GROMACS. Have you followed Intel’s “Getting started guide”?

  • If sycl-ls is showing the GPU, could you share the md.log file from the unsuccessful GROMACS run?

It’s always good to check, but in this case, the warnings are completely harmless.
