As the successor of
was started to find some answers to questions the first project left open. The main problem encountered in examining SX-4 and SX-5 at the
High Performance Computing Center Stuttgart (HLRS)
was the impossibility to test these machines with all planed trials concerning mixed workloads due to software hangups. To illustrate the problem as well as the undertaken efforts to solve it, we will divide this report into three parts. First,
the used benchmark system is described briefly. Thereafter, the results and problems investigating the SX vector computers are shown. In the final part the changes made to
as well as the new findings are discussed.
