Changes to this message: Update
Status update Jan 17 16:15 Both ICE and UV systems are now available
again. However, running Intel MPI programs on the UV does not work in
many cases; this also may impact applications installed by LRZ.
If you obey all of the following rules when using Intel MPI things may
work:
* Use version 4.1 of Intel MPI (module load mpi.intel/4.1)
* Use 64 tasks or less
We will continue investigation of this problem but cannot promise a
quick resolution.
Programs using sgi MPT are (to our present knowledge) not impacted by
this problem.
Please also note that the update work on the ICE was only partially
successful; a separate maintenance window will be announced in a few
weeks for completion of the updates.
-----------------------------------------------------------------------
Dear users of the Linux-Cluster systems at LRZ,
due to a necessary operating system update the ICE and UV systems will
be unavailable for user operation for a few days. The maintenance
starts on Monday, Jan 14 at 8:00. We expect the systems to be returned
to user operation during the afternoon of Jan 16.
Further changes that apply post-maintenance will be announced via this
document.
