[RegCNET] About the limitation of the computing of parallel RegCM

[XUNQIANG BI]

Dear all:

When you run RegCM in parallel way, please not split the domain
too much, JXP (JXP=MJX/NPROC, in regcm.param2) should be greater
than 2. Otherwise, it would cause problem and you'll get wrong
results.

For example, if you run a domain 150x128L18 (128 is the number of
points from west to east). then you cannot use 64 CPUs for
parallel RegCM computing.

Please follow the above rule before we have found a fix for this.

Best Regards,
Xunqiang Bi
