Hi All,
currently DIRAC does not support submitting multi core jobs to ARC CEs.
When we enabled multicore jobs for CMS on our ARC CEs, we had to introcude a special file:
[root@cetest01 rte]# cat ENV/MC8
#!/bin/sh
if [ -z $1 ] || [ $1 == 0 ] ; then
# Enable Multi-core PE
export joboption_nodeproperty_0="
grid8.pe"
fi
and CMS requires this file in their rsl.
