I'm sorry to bother you with a stupid question.
we intend to have for a short period of time, some nodes with 1.4.3 and
others with 1.4.1 (before upgrading everyone to 1.4.3).
I made various test and found both versions to be running together quite
well with a mixed set of nodes.
my tests were quite simple, I compiled and ran mpi hello_worlds with
It wouldn't be serious for me to assume both versions fully compatible
after these tests -and I must admit I lack the time and technical
knowledge to run further testing.
has anyone any insight on what have changed that would break compatibility?
I guess nothing, since they are the same major.minor :)
