In this add-on course to the parallel programming course special topics are treated in more depth, in particular performance analysis, I/O and PGAS concepts. It is provided in collaboration of Erlangen Regional Computing Centre (RRZE) and LRZ.
Each day is comprised of approximately 5 hours of lectures and 2 hours of hands-on sessions.
▪ Intel Tracing Tools: MPI tracing and correctness checking
▪ Intel Threading tools for OpenMP correctness checking and profiling
▪ Profiling on SGI Altix systems: histx and lipfpm
▪ Introduction to Scalasca
▪ Parallel application performance analysis with Scalasca
▪ Parallel input/output with MPI-IO
▪ I/O tuning on high performance file systems
▪ Portability of binary files, big/little endian issues
▪ Using I/O libraries (pNetCDF, HDF5)
▪ Introduction to the PGAS languages Coarray Fortran and UPC: Partitioned global address space languages have emerged as an alternative to other parallel programming models, promising a shorter development cycle due to improved programmability while keeping the performance level on par with MPI. This course introduces the parallel facilities integrated into the Fortran language (coarrays) and the C language (unified parallel C), respectively. A hands-on session allows to experiment with the new concepts, using prototype implementations on LRZ's HPC systems.
