  1. Problems with Radioss in HPc Cluster

    Thank you Andy Now it work with one node and many cores but for many nodes and many cores it does not work. I also found this syntax for Intel Cluster [radioss@host1~]$ cp $ALTAIR_HOME/hwsolvers/common/bin/linux64/radflex_2017_linux64 [radioss@host1~]$ $ALTAIR_HOME/hwsolvers/radioss/bin/linux64/s_2017_linux64 –input [ROOTNAME]_0000.rad –np [Nspmd] [radioss@host1~]$ [Intel MPI path]/bin/mpirun -configfile [cgfile] Could you tell me more about the [Intel MPI path] because I use HPC cluster so I do not know the path of Intel MPI.

  9. cluster access

    Hi George Where can we find the instruction for using Radioss with cluster?
  10. Hello I have just started using Radioss 2017 in HPc Cluster. For the SLURM File I use the syntax like that #!/bin/bash #SBATCH --nodes=1 #SBATCH --ntasks-per-node=1 #SBATCH --time=01:00:00 #SBATCH --job-name=altair-radioss #SBATCH --mem=1G # Setup input file(s) following your case INPUT1=v14_run_0000.rad INPUT2=v14_run_0001.rad # Setup custom library path if necessary export LD_LIBRARY_PATH="$HOME/my_user_library:$LD_LIBRARY_PATH" # Load Altair module module load altair/2017.2 # Run Radioss on single core if [[ ($SLURM_JOB_NUM_NODES == 1) && ($SLURM_NTASKS_PER_NODE == 1) ]]; then radioss "$INPUT1" # Run Radioss on many core elif [[ $$SLURM_JOB_NUM_NODES == 1 ]]; then radioss -nthread $SLURM_NTASKS_PER_NODE "$INPUT1" # Run Radioss on many core of many nodes else module load intel/2013/intel-mpi $ALTAIR_HOME/hwsolvers/radioss/bin/linux64/s_2017.2_linux64 -i "$INPUT1" -nt 1 -np $SLURM_JOB_NUM_NODES mpiexec $ALTAIR_HOME/hwsolvers/radioss/bin/linux64/e_2017.2_linux64_impi -i "$INPUT2" -nt 1 fi It worked. But when I changed #SBATCH --nodes=2 #SBATCH --ntasks-per-node=2 It did not work. Could you please explain me why? Thank you
