I have recently installed gromacs-2018.6 on my desktop PC. It has NVIDIA-GeForce-RTX-1080-Ti gpu and I am using CUDA-11.7. I used the following cmake command:

cmake … -DGMX\_BUILD\_OWN\_FFTW=ON -DREGRESSIONTEST\_DOWNLOAD=OFF -DGMX\_MPI=off -DCMAKE\_INSTALL\_PREFIX=/home/softwares/gromacs-2018.6 -DGMX\_GPU=CUDA -DCUDA\_TOOLKIT\_ROOT\_DIR=/usr/local/cuda-11.7/ -DREGRESSIONTEST\_PATH=/home/regressiontests-2018 -DGMX\_CUDA\_TARGET\_SM=“35;50;52;53;60;80;86;70;75” -DGMX\_SIMD=AVX\_512 -DGMX\_USE\_RDTSCP=ON

this was followed by “sudo make” → this runs without any error  
then I ran “sudo make check” —\> it is showing one test failed: 8 - GpuUtilsUnitTests (Failed)  
However, I have installed gromacs using “sudo make install” without errors and currently running simulations as well.

What is this GpuUtilsUnitTests error and is there a way to get rid of it or it is something we can ignore? Any suggestion is much appreciated, thank you.

Hi!

Please, share the full test log. `GpuUtilsUnitTests` is a collection of many tests, so would be helpful to know which tests fail and what are messages.

A few thoughts:

1. Any reason you’re using such an old version of GROMACS? It’s not really supported anymore.
2. `-DGMX_CUDA_TARGET_SM=61` is a better fit for your GPU (and will save your some compilation time compared to supplying the full list).
3. `sudo` is typically only required when doing `make install`; using it for `make` and `make check` can have unintended consequences due to different permissions / environment inside the `sudo` (not always for the best). I don’t think it is likely to be causing your issue, but if all else fails, clearing the build directory and running `cmake`/`make`/`make check` without `sudo` might be worthwhile to try out.
