Hi all, following my previous post regarding anomalous behavior of gromacs on running with two gpus, I have some new elements to add. I tested the workstation with two tools for gpu and cpu I found on the web (gpu_burn and stress); I ran the two of them at the same time for two hours pushing both gpus (2 x 250 W) and cpu (250 W), and no error reports or overheating have resulted, so I would say that the hardware seems to be stable. Despite this, I found something that probably could be not normal during gromacs compilation: setting -DGMX_SIMD=AUTO, results in "SIMD instructions: NONE"; in this condition I can run gromacs without any unexpected crash, even though a little less efficiently; setting -DGMX_SIMD to AVX_256, AVX2_128 and AVX2_256 produces clean compilation and installation (with all the tests passed), but on running the sudden turning off happens in the conditions I had described in the previous posts (gmx mdrun -deffnm run -nb gpu -pme gpu -ntomp 28 -ntmpi 1 -npme 0 -gputasks 00 -pin on -pinoffset 0 -pinstride 1 plus gmx mdrun -deffnm run2 -nb gpu -pme gpu -ntomp 28 -ntmpi 1 -npme 0 -gputasks 11 -pin on -pinoffset 28 -pinstride 1) Do you think that there could be a relationship between SIMD options setting and the crash of the system? Does anyone have any idea about the reason why gromacs does not seem to automatically recognize any options for my AMD threadripper? Can there be any solutions for this? Thanks again Stefano
