Dear user,

 

I’m try run NAMD on 4 node each with 2 GPU Tesla K80

 

My PBS file

 

#PBS -N test_nand_GPU

#PBS -l nodes=n004+n005+n006:ppn=28:gpus=2

 

 

cd $PBS_O_WORKDIR

 

/opt/shared/NAMD_2.13-multinode-gpu/charmrun  /opt/shared/NAMD_2.13-multinode-gpu/namd2 +idlepoll +p 12 +devices 0  ++ppn 4  run_fixed/md_run.namd | tee md2.log

 

When set “+devices 0,1” not run, only run when set to 0 .

 

How can correct it?

 

Help me.

 

Geo.
