As for info in log filehead, please see following: ![image](https://europe1.discourse-cdn.com/flex017/uploads/bioexcel1/original/2X/4/4d664d80eb94e87e506a2d6738537110155b4e21.png) I saw another similar situation but I’m not sure if he/she has solved. topic: > [@Simulations hang on AMD CPU system](https://gromacs.bioexcel.eu/t/simulations-hang-on-amd-cpu-system/5127): > > GROMACS version: 2022.3 GROMACS modification: No I am attempting to run ~150 ns simulations that take ~12 hours on a single-node AMD CPU system, but the simulations sometimes hang after ~8 hours of run time (i.e. the system resources remain occupied but the simulation fails to progress). This is the same issue reported [here](https://gromacs.org-gmx-users.maillist.sys.kth.narkive.com/c2dRlO5U/gmx-users-simulation-freezes-but-the-job-keeps-on-running), but my understanding is that the work-around solution of using intelmpi is incompatible with my system. For reference, here is my GROMACS and system info: GROMACS versi… Now, AGAIN, I’m stuck here… Please kindly help.
