Update (2018-12-07, 3:30 pm):
Both login nodes of Superior are accessible and usable as before.
2018-12-06, 7:15 pm
superior-login1.research.mtu.edu will be unavailable for about an hour starting noon on Friday, 7th December 2018. Ongoing simulations will not be affected.
superior-login2.research.mtu.edu may be used to continue the work during this maintenance window.
Update (2018-12-17, 8:45 am):
Any running/waiting simulation has been terminated with administrative privilege, any user still logged in has been logged out, and login and compute nodes of Superior and Portage have been powered down.
2018-11-07, 10:05 am:
Superior and Portage will be undergoing pro-active maintenance routine during the finals week of Fall semester to ensure smooth and sustainable operations in 2019. The systems will be powered down at 8 am on Monday, 17th December 2018. They will be accessible and usable from 9 am on Monday, 24th December 2018. Researchers are requested to ensure that the simulations are completed (or at least checkpointed) and transfer the necessary data to your local workstation to continue the analysis, manuscript preparation, etc. during the maintenance window.
Should the work go as planned and completed ahead of time, Portage and Superior will be made accessible sooner. In the unlikely event that things take longer than expected, you’ll be notified as well.
In order to ensure that Superior and Portage continue to operate consistently at a high level, IT will be performing proactive maintenance work starting at 8 am on Tuesday, 5th May 2014.
All nodes — including the front end, login and storage nodes — will need to be powered down. Any running simulation at that time will be automatically terminated without further notice.
As such, researchers are requested to complete (or at least checkpoint) their simulations, and transfer any necessary data to a local workstation so that analysis, visualization, and manuscript preparation work can still be continued.
Superior and Portage should be accessible as before starting at 8 am on Friday, 8th May 2014.
An additional variant of VASP to facilitate implicit solvation model computations has now been compiled (for version 5.3.3) and is now available for use on all clusters. Necessary job submission script can be generated via qgenscript.
Researchers specifically authorized to use VASP are strongly recommended to verify the results for simpler/inexpensive systems with available literature before proceeding ahead with subsequent, production quality attempts for bigger/complex systems.
An additional variant of VASP to facilitate spin orbit coupling computations has now been compiled (for versions 5.3.3 and 5.3.5) and is now available for use. Necessary job submission script can be generated via qgenscript.
Researchers are strongly recommended to verify the results for simpler/inexpensive systems — preferably with both versions when permissible — with available literature before proceeding ahead with subsequent, production quality attempts for bigger/complex systems.
R 3.1.2 (Pumpkin Helmet; Release Notes) has been compiled and is now available for use on all computing clusters. Necessary job submission script can be generated via qgenscript.
Researchers are strongly recommended to re-run a previously successful simulation with this newer version and make sure that the results are consistent before proceeding ahead with subsequent, production quality attempts.
Unless there is a request from researchers to do otherwise, 3.1.1 (Sock it to me) will be retired on Friday, 27th March 2015.
MATLAB R2014b (Release notes) has been installed and is now available for use on all computing clusters. Necessary job submission script can be generated via qgenscript.
Researchers are strongly recommended to re-run a previously successful simulation with this newer version and make sure that the results are consistent before proceeding ahead with subsequent, production quality attempts.
Unless there is a request from researchers to do otherwise, R2013b will be retired on Friday, 27th March 2015.
R 3.1.1 (Sock it to Me; Release Notes) has been compiled and is now available for use on all computing clusters. Necessary job submission script can be generated via qgenscript.
Researchers are strongly recommended to re-run a previously successful simulation with this newer version and make sure that the results are consistent before proceeding ahead with subsequent, production quality attempts.
Telcom will be upgrading the software on the data center switches, and as such, all computing clusters housed in GLRC will be inaccessible during 6-7 am on Thursday, July 17th 2014.
Running simulations will be unaffected.
