- 05 February 2009: The ARL DSRC will be performing a major
system upgrade on MJM over the upcoming President's day holiday. The outage will start
on 0600 on Monday, February 16th, and the system should be returned to service by 1000
Tuesday, February 17th. Should all of our installations and testing go well, we hope
to return the system to our users earlier. We will be upgrading from the infiniserve
to the OFED stack, and also from SLES9 to SLES10. Because of this major upgrade, and
changes in node to node communications, all users running parallel jobs will have to
recompile their codes. There are no changes required to the compile their codes. There
are no changes required to the compile and link options when rebuilding, but this is a
necessary step.
After the OFED upgrade on MJM, the following module changes will be made:
Old New ------------- ------------------------- intel-mk18.1 intel-cluster-toolkit-3.2 intel-cmk19.1 intel-cluster-toolkit-3.2 intel10.0 intel11.0 pgi6.2 pgi7.2 pgi7.0 pgi8.0 openmpi-1.2 openmpi-1.3
