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,

Command used to run the test '': mpirun -np 8 opal --commlib mpi

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?
