Hello Norman the input files is just fine, I made one small change not related to your problem.
Can you send me the std-output of your run? On which cluster do you run?
Are you sure that MPI is installed properly i.e. can you run a canonical MPI test - for example
calculating Pi - (this test comes with every MPI distribution).
You should also contact Fred Jones, I remember having similar problems when I was at Triumf
in the beginning of this year.
Cheers Andreas

<isis.in>Hi Andreas,I'm trying to do space charge calculations using parallel computing on OPAL-T, butit appears only 1 core is being used.This is my fieldsolver parameters:Fs1:FIELDSOLVER, FSTYPE=fft, MX=32, MY=32, MT=2024,PARFFTX=true, PARFFTY=true, PARFFTT=false,BCFFTX=open, BCFFTY=open, BCFFTT=open,BBOXINCR=1, GREENSF=INTEGRATED;Command used to run the test 'isis.in': mpirun -np 8 opal --commlib mpi isis.inWhen it's being run, all 8 cpu cores are active, but only one is doing thecalculations. Furthermore, this run actually took an hour more than a previousrun using a single core.Am I missing some configurations?Regards,Norman
