Due to physical rearrangements in the server room the tape robot hosting /migrate and /bcmhsm will be unavailable today after 12:00 for several hours. Updates will be posted here.

Update 2017-09-11:

Uni Computing is experiencing troubles with the backend holding /migrate and /bcmhsm and it is unknown yet when this will be fixed. As these file systems were supposed to be already decommissioned earlier this year in June, we will not mount those back in ordinary place even after the file systems are healthy. However, we will finish transfer of IMR/HI files as it was agreed as soon as the filesystem is healthy. We will issue a separate update for this.
Other users  than IMR/HI needing files from those file systems are advised to contact Uni Computing helpdesk at trouble@computing.uni.no.

PGI 16.05, CCE 8.5.1 and CrayPat 6.4.1 are installed on Hexagon as non default versions.


As the newer CCE and CrayPat installations are rather experimental, to access version 8.5.1 of the Cray compiler and 6.4.1 version of the CrayPat one needs to run:

module use /opt/cray/pe/modulefiles

NB. No extra steps are required to access PGI 16.05

Scheduler system on Hexagon is not well working with mppdepth directive.

Due to increased usage of OpenMP on the machine we had to stop supporting mppdepth. 

The new way of running OpenMP is as simple as it was before with mppdepth.

Updated documentation on how to run an OpenMP job you can find here
