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. More precisely, the tutorial was be split into three sessions. The first two sessions feature 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) comprises practical exercises which are meant to illustrate some of the content presented in the earlier parts and is held at:
Computer-Lab: W01 0-008: Thu, 21.11.13 - 09-12 Uhr
The target audience of this 1st HPC tutorial are new Users of the local HPC system, for whom, in order to benefit from the tutorial, the skills of reading and writing C-programs are of avail.
The precise 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
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 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 Parts I+II
