Posted: 2007-04-12

Dear ICHEC users,

Contents:

1. Scheduled downtime
2. ICHEC Users Council
3. ICHEC Training programme
4. Updated programming environment (hamilton and walton)
5. Acknowledging ICHEC in publications / reporting publications
6. Met Eireann / ICHEC collaboration

------------------------------------------------------------------------
1 – Scheduled downtime
------------------------------------------------------------------------

Our next scheduled downtime (SDT) will take place on Monday 16th April, between 09:30 and 20:30. Both hamilton and walton will be affected, with possible network interruptions between 11:30 and 13:00. Details of the work to be undertaken are as follows:

- Apply software update to core switch
- Update BIOS and firmware on compute nodes
- Kernel updates to address current SATA instability problem
- Fix existing disk problems on a number of machines

See the ICHEC systems status page for further information.

------------------------------------------------------------------------
2 – 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 have extended the feedback period until Wednesday 18th April. All PIs are advised to take the time to consider this proposal and send their feedback to JC Desplat. Thanks to all who have already done so.

------------------------------------------------------------------------
3 – ICHEC Training programme
------------------------------------------------------------------------

ICHEC is pleased to announce continuation of its HPC training programme by hosting (in collaboration with NUI, Maynooth and UCD) two week-long training programmes during the month of May. A third series of courses will be held in Galway later on. Full details (including registration) can be found on ICHEC's training webpage at http://www.ichec.ie/training.

Provisional Timetable

1. National University Ireland, Maynooth (NUIM) (May 7th- May 11th 2007)
2. University College Dublin (UCD) (May 14th-18th 2007)
3. National University Ireland, Galway (NUIG) (early June - date TBA)

An overview of the week-long training programme is as follows:

* Day 1 - Introduction to High Performance Computing
* Day 2 and 3 - Introduction to MPI
* Day 4 and 5 - Introduction to OpenMP

------------------------------------------------------------------------
4 – Updated programming environment (hamilton and walton)
------------------------------------------------------------------------

Our debugger DDT has recently been upgraded to v2.0 on both walton and hamilton.

On Walton, DDT 1.10 is still installed but is no longer the default version. Both versions are managed under the module environment. Use:

module load ddt/1.10 to load DDT 1.10 and module load ddt to load DDT 2.0

On hamilton, v2.0 is still a beta version so the default version is still v1.10. Thus,

module load ddt will load v1.10 and module load ddt/2.0-beta will load v2.0 beta.

V2.0 now includes OpenMP support, improved user interface, heap overflow/underflow memory debugging, extended signal information, a graphical installer and more! Further information about DDT can be found at http://www.allinea.com/index.php?page=48.

------------------------------------------------------------------------
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.

6 – Met Eireann / ICHEC collaboration
------------------------------------------------------------------------

The Irish Centre for High-End Computing (ICHEC) announced today that it is embarking on a new collaboration with Met Eireann, the Irish National Meteorological Service. For further information, see http://www.ichec.ie/news/1175611451
