Re: [gmx-users] GPU job failed

Hi, My first guess is that the implementation of PLUMED doesn't support this. Does a normal non-PLUMED simulation run correctly when called in this manner? Mark On Wed, Aug 2, 2017 at 9:55 AM Albert wrote: > Hello, > > I am trying to run Gromacs with the following

[gmx-users] GPU job failed

Hello, I am trying to run Gromacs with the following command line: mpirun -np 4 gmx_mpi mdrun -v -g 7.log -s 7.tpr -x 7.xtc -c 7.gro -e 7.edr -plumed plumed.dat -ntomp 2 -gpu_id 0123 but it always failed with the following messages: Running on 1 node with total 24 cores, 48 logical cores,

Re: [gmx-users] GPU job failed

Hi, from the double output it looks like two identical mdruns, each with 1 PP process and 10 OpenMP threads, are started. Maybe there is something wrong with your MPI setup (did you by mistake compile with thread-MPI instead of MPI?) Carsten On 09 Sep 2014, at 09:06, Albert

Re: [gmx-users] GPU job failed

I recompiled Gromacs-5.0.1, finally it works now Probably I made some mistakes in previous compiling thanks a lot guys regards Albert On 09/09/2014 09:16 AM, Carsten Kutzner wrote: Hi, from the double output it looks like two identical mdruns, each with 1 PP process and 10 OpenMP

Re: [gmx-users] GPU job failed

Hi, It looks like you're starting two ranks and passing two GPU IDs so it should work. The only think I can think of is that you are either getting the two MPI ranks placed on different nodes or that for some reason mpirun -np 2 is only starting one rank (MPI installation broken?). Does the same

Re: [gmx-users] GPU job failed

Same idea with Szilard. How many nodes are you using? On one nodes, how many MPI ranks do you have? The error is complaining about you assigned two GPUs to only one MPI process on one node. If you spread your two MPI ranks on two nodes, that means you only have one at each. Then you can't

Re: [gmx-users] GPU job failed

thanks a lot for reply both Yunlong and Szilard. I don't set up PBS system and nodes in the workstation. In the GPU workstation, it contains 1 CPU with 20 cores, and two GPUs. So it is similar to 1 nodes with 2 GPUs. But I don't know why 4.6.5 works, but 5.0.1 doesn't ... Thx again
