[MITgcm-support] max number of processors

Wed Mar 17 07:54:17 EDT 2010

Just increase.

MAX_NO_PROCS used to be 128
then changed to 1024 6 years ago and then 2048
to accommodate large integrations on Columbia.

I don't think there's any other consequence in code
except that eeboot_minimal stops if you request more
processes than MAX_NO_PROCS
