Please state your opinion of High Performance Computing Services in Sweden by completing the HPC User Survey, issued on behalf of the Swedish National Infrastructure for Computing (SNIC): http://www.snic.vr.se/SNIC_Evaluation. Deadline for submission: September 24.
  • 2004-07-09 Monolith and SGI3800 are now back in service after the security breach, for further information see the Systems Log.
  • 2004-07-01 New user guide available electronically.
  • 2004-06-30 The SGI3k machine is back in service. However, for security reasons all users have been issued new passwords by paper mail again. These letters were sent 2004-06-29. For Monolith the timeplan is not yet clear. The system is still down for analysis and verification following the last intrusion, and will also go through a hardening process. It will likely remain unavailable for the rest of this week, at least. Our users will receive further information as we have it. Please accept our apologies for the inconvenience.
  • 2004-06-29 SNAC-projects beginning 2004-07-01 and new NSC-users connected to them. NSC users who have been awarded time on NSC resources through SNAC are invited to contact support in order to be transferred to their new project. Brand new NSC users should fill in an Agreement form and send it by regular mail to NSC. If you have been awarded time on Swegrid, please see www.swegrid.se for information on how to gain access.
  • 2004-06-23 New intrusion. Another intrusion has been detected. NSC systems are currently undergoing integrity verification. We ask all users to kindly verify that their ssh clients have not been tampered with. If you don't know how to do this yourself, please contact your system administrator.
  • 2004-06-16 Security breach - accounts disabled. During the last few days a number of intrusions have been detected on NSC systems. User accounts have been accessed using stolen passwords. In a couple of cases the intruder has managed to gain elevated priviliges. Apparently the passwords were initially stolen from users who used ssh to log in to NSC systems from compromised computers on Chalmers. Due to the widespread nature of this security breach, all accounts on all NSC systems will be disabled. New passwords will be sent out by (paper) mail. More information on that process will be available as we work out the details. If you have used ssh (or scp) to access other systems from NSC systems the last few days, you are strongly advised to change your password on those other systems. Also, please inform the administrators of those systems about this issue. (Refer them to support@nsc.liu.se for further technical information.) We understand that these measures will be a great inconvenience to our users. However, we have to treat security issues in the strictest possible fashion, and we hope for your understanding.

Two courses were given at NSC in Linköping by instructors from Manchester Computing.

1. Introduction to Programming with MPI Instructor: Dr Mike Pettipher, Manchester

Overview:

MPI (Message Passing Interface) has emerged as the de facto standard for writing portable, message-passing programs in parallel processing environments. This course introduces the basic essentials of MPI, yet the material covered is sufficient to parallelize a wide range of serial codes.

Prerequisites:

The ability to program in Fortran or C and familiarity with Unix. Some acquaintance with the terminology of High Performance Computing, such as that covered by the course Introduction to High Performance Computing, is also desirable.

Duration:

A one day workshop with lectures and practical sessions.
Lectures Tuesday 8-12, February 26, 2002.
Practical session Wednesday 8-17, February 27, 2002 (together with OpenMP).

Location:

Valla campus, Linköping
Tuesday: Lectures in room G 35 (G-house, second floor, same building as NSC) Floor plan
Wednesday: Computer exercises in SU 15, SU 16 (B-house, first floor) Floor plan

Topics covered:

  • The message-passing paradigm
  • MPI fundamentals (communicators, rank and size)
  • Point to point communication (messages, send and receive operations)
  • Basic collective communication (reduction operations, broadcast, synchronisation, gather and scatter)
2. Shared Memory Parallelisation with OpenMP Instructor: Dr Neil Stringfellow, Manchester

Overview:

OpenMP can be used to run Fortran and C programs in parallel on a shared memory computer. The OpenMP specification is now widely accepted and suitable compilers are now provided by all major hardware vendors, including SGI, Sun, Compaq/DEC, Intel, HP and IBM. To use OpenMP you simply add directives to your code.

Prerequisites:

You should have used either Fortran 77 or Fortran 90 to write programs. Familiarity with Unix, emacs or vi, and the X Window System is highly desired.

Duration:

This is a 1 day course.
Lectures Tuesday 13-17, February 26, 2002.
Practical session Wednesday 8-17, February 27, 2002 (together with MPI).

Location:

Valla campus, Linköping
Tuesday: Lectures in room G 35 (G-house, second floor, same building as NSC) Floor plan
Wednesday: Computer exercises in SU 15, SU 16 (B-house, first floor) Floor plan

Topics covered:

  • All the important directives
  • How to parallelise your code (plenty of hands-on exercises with emphasis to the practical use of OpenMP)
  • Brief overview of concepts of parallel programming
  • Brief introduction to the performance analysis tools perfex and SpeedShop
  • Practical exercises


Both of the courses do involve a significant component of practical sessions. It is believed that this is the best way of re-inforcing the lecture material. The MPI exercises have been validated on T3E and Origin systems and the OpenMP exercises have been validated on Origins.
