Hi Andreas,

I'm trying to do space charge calculations using parallel computing on OPAL-T, but

it 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.in

When it's being run, all 8 cpu cores are active, but only one is doing the

calculations. Furthermore, this run actually took an hour more than a previous

run using a single core.

Am I missing some configurations?

Regards,

Norman
