The SAS High-Performance Analytics environment uses
Message Passing Interface (
MPI) communications, which requires you to define one port range per active job across
the machine cluster or data appliance.
(A port range consists
of a minimum of four ports per active job. Every running monitoring
server counts as a job on the cluster or appliance.)
For example, if you
have five jobs running simultaneously across the machine cluster or
data appliance, you need a minimum of 20 ports in the range.
The following example
is an entry in tkmpirsh.sh for five jobs:
export MPICH_PORT_RANGE=18401:18420
Edit tkmpirsh.sh using
the number of jobs appropriate for your site. (tkmpirsh.sh is located
in /installation-directory/TKGrid/.)
Then, copy tkmpirsh.sh across the machine cluster or data appliance.
