OpenMP
OpenMP is a parallelization method available for the programming languages Fortran, C and C++, which is targeted toward use on shared memory HPC systems. Since the OpenMP standard was developed with support from many vendors, programs parallelized with OpenMP should be widely portable.
A comprehensive introduction to directive-based OpenMP programming can be found on the LRZ-Webpages. The statements made there are transferable to the hpda terrabyte CPU-cluster.
A simple OpenMP example can be found on the CARA and CARO Wiki-Pages (DLR internal only).
