Material related to the first tutorial on "High Performance Computing" (HPC) which took place at the University of Oldenburg from 19.11.2013 to 21.11.2013. The tutorial was be split into three sessions. The first two sessions featured the parts I and II (listed below) and were held at:
Seminar-Room: W04 1-162:
Tue, 19.11.13 - 14-16 Uhr
Wed, 20.11.13 - 16-18 Uhr
The third session (part III) comprised practical exercises which were meant to illustrate some of the content presented in the earlier parts and was held at:
Computer-Lab: W01 0-008:
Thu, 21.11.13 - 09-12 Uhr
The target audience of this 1st HPC tutorial were new Users of the local HPC system, for whom, in order to benefit from the tutorial, the skills of reading and writing C-programs were of avail.
The full program of this 1st HPC tutorial reads:
Part I
1. Cluster Overview:
- System Overview
- Available compilers
- Modification of user environments via "module"
- Available parallel environments
- Available Libraries
NOTES:
- The slides related to the presentation will soon be available.
Part II
2. Introduction to the usage of SGE:
- General Job submission (specifying job requirements)
- Single Slot jobs (how to compile submit and monitor status)
- Parallel Jobs (openMPI, impi, smp)
- Monitoring and Controlling jobs (qstat, qrsh, qacct)
3. Debugging:
- Compiling programs for debugging
- Tracking memory issues
- Profiling
4. Misc:
- Logging in from outside the university
- Mounting the HPC home directory
- Parallel environment memory issue
- Importance of allocating proper resources
NOTES:
- The slides related to the presentation can be found here.
- The content of part II closely follows the HPC User-Wiki entry Brief Introduction to HPC Computing.
Part III
5. Exercises (Computer-Lab):
- Simple example programs
- Practical aspects not covered in part II
NOTES:
- The example programs can be downloaded here.
- A brief documentation of some of the examples (i.e. those which are notdiscussed in the Brief introduction to HPC Wiki page) can be found here
