Hello,

       I am attempting to run MODELLER in parallel on a cluster with multiple nodes. The script I used is below:

from modeller import *
from modeller.parallel import *
from modeller.automodel import *

log.verbose()
j = sge_pe_job()
env = environ()
a = automodel(env, alnfile='2NT2-mult.ali',
              knowns=('1m3gA','2wgpA','2hxpA'), sequence='2NT2',
              assess_methods=(assess.DOPE, assess.GA341))
a.starting_model = 1
a.ending_model = 25
a.use_parallel_job(j)
a.make()

However, once I submit the job (using the parallel environment mpich), the job runs on the master node fine but fails on all the slave nodes. The error is also ambiguous:

within the slave1 output file (identical for all other output files except the slave0 one which runs fine):
error: executing task of job 76003 failed:

Thanks in advance for the help!
