Dear ICHEC users,

Contents:

1. ICHEC Users Council
2. ICHEC Training programme
3. New programming environment (walton)
4. Major update on hamilton
5. Acknowledging ICHEC in publications / reporting publications

------------------------------------------------------------------------
1 – ICHEC Users Council
------------------------------------------------------------------------

A proposal to establish an independent ICHEC Users Council has been posted on our News section (see http://www.ichec.ie/news/1173971818). We would advise all PIs to take the time to consider this proposal and send their feedback to JC Desplat no later than Tuesday 27th March.

------------------------------------------------------------------------
2 – ICHEC Training programme
------------------------------------------------------------------------

We are glad to announce the completion of a brand new 2-day course on OpenMP. This course will be of particular interest to users of the shared memory service, and users with little experience of HPC as OpenMP provides an easy path to HPC.

See http://www.openmp.org and http://www.openmp.org/drupal/node/view/11 for further information on OpenMP.

Finally, we are currently finalising details of our next courses in UCD, NUI Maynooth, and NUI Galway. The first of these three training sessions is expected to take place in late April/early May. Two of these sessions will include our 3-day "Intro to HPC" + "Intro to MPI", while the third one will consist in a full week with the above two courses + "Intro to OpenMP".

Exact details will follow on our web pages.

------------------------------------------------------------------------
3 – New programming environment (walton)
------------------------------------------------------------------------

PathScale 3.0 is now available on Walton but it is not currently the default version of the compiler. PathScale 2.5 is still installed and is the default version loaded by 'module load pathscale'. PathScale 3.0 can be loaded with:

module load pathscale/3.0

Compatible versions of MPICH and MPICH2 have also been built and can be loaded with:

module load mpich/path3.0
or
module load mpich2/path3.0

... as appropriate. For further information about this new release, see http://www.pathscale.com/docs.html

------------------------------------------------------------------------
4 – Major update on hamilton
------------------------------------------------------------------------

A complete reinstall of the hamilton servers took place during our March maintenance session. The most significant change include our update from Bull's BAS3V1.5 to BAS4V5.1. As such users are advised to completely rebuild their codes from source. Current versions of the Intel compilers (9.1), MKL (9.0) and Trace Analyser (7.0.1) have all been installed installed.

All other third party applications such as Abaqus, Gaussian and DDT are also now managed via modules. Use 'module avail' to list available modules.

Note also that our scheduling policy is likely to change next week, following consultations with users of the shared memory service.

------------------------------------------------------------------------
5 – Acknowledging ICHEC in publications / reporting publications
------------------------------------------------------------------------

We would appreciate a formal acknowledgement of ICHEC by inclusion in any resulting publications of the following sentence or some variation thereof:

"The authors wish to acknowledge the SFI/HEA Irish Centre for High-End Computing (ICHEC) for the provision of computational facilities and support."

See our FAQ.

We would also appreciate if you could let us know when such publications are being accepted for publication, as this constitutes one of the major metrics by which the scientific impact of ICHEC will be assessed.

This list will be kept up to date at http://www.ichec.ie/publications.
