The following software and libraries have been updated on hexagon:

MPI
xt-mpt 4.1.1 -> 5.0.0
MPI 2.2 compliance, except Dynamic Process Management

Compilers
PGI 10.4 -> 10.5
GCC 4.4.3 -> 4.4.4
xt-asyncpe 3.9 -> 4.0
java (security update) jdk1.6.0_20


Math/libs

xt-libsci 10.4.4 -> 10.4.5

LibSci 10.4.5 includes minor increases in functionality/support
of distributed CRAFFT routines. The enhancement improves the
coverage of 2d and 3d FFT routines by allowing real type work
arrays and input arguments for all transform types.

CRAFFT offers a simpler interface to improve application developer
productivity. In some cases the distributed CRAFFT 2.1 transforms
exhibit up to 10% speedup over comparable FFTW2 distributed
transforms.

Users requiring more information on usage should see the
intro_crafft manpage.


PETSc 3.0.0.10 -> 3.1.00

This new version of PETSc includes several changes including
performance enhancements of the sparse kernels used in the
incomplete LU preconditioning for AIJ and BAIJ matrix formats.
In Cray PETSc, these new kernels are further improved through
the new routines from Cray Adaptive Sparse Kernels (CASK).
In addition, the latest SuperLU-4.0 is included in this new
PETSc product.

More detailed information about the official PETSc-3.1 release is
available at

SuperLU-4.0 information can be found at

Due to over memory usage , compute-1-32 crashed last night, we are trying reinstall that node , but currently having some hardware failure issue,
we are still working on it , hope fully compute-1-32 will be up tomorrow, we will keep you updated.

We are sorry for incontinence.

UPDATE 26th May 11:47 compute-1-32 is up and running.

One of the file server serving work and home file system on fimm cluster crashed 14:10, all jobs using work file system crashed due to Stale NFS file handle.

File server rebooted , and home file system and work file system mounted back to all compute nodes.

Hexagon has got NCL version which is capable to run with aprun. Latest module version 5.2.0 is aprun compatible. This version is loaded by default if you do module load ncl_ncarg.

If you miss some features and you want to run ncl on login node, then module load ncl_ncarg/5.2.0-login shall be used.

Hexagon will have a scheduled maintenance on Thursday May. 6th from 12:00.
This is to fix problem with cabinet 7.
The queue have a reservation in place such that only jobs that can complete (according to asked for walltime) before the maintenance will start.
This note will be updated when we have more information.

Update: Maintenance has been moved to Monday May 10th, from 12:00

Update: 10.05, 18:20 Maintenance finished, machine is back online.
