That is incorrect. HPL exercises only the CPU/memory subsystem (mostly CPU). It doesn't test interconnect performance. The program "solves a dense system of linear equations" and that's it. It is a "show off" test which demonstrates maximal FP throughput of the processor. The HPC Challenge is a collection of 7 programs, including HPL, that perform a variety tests to more accurately show the real world parallel performance of a parallel HPC system. Keep in mind that these tests are designed to show the differences in performance among parallel supercomputers and compute clusters with thousands to hundreds of thousands of cores. They are not targeted to the type of single system "historical" performance data you seem to be collecting. There are probably better programs available to meet your needs. Debian may have an HPCC package, but this list is not a good place to ask for help as there are likely no HPC users/experts on the debian-users list who are familiar with these things. I suggest you ask on one of the Linux cluster lists, or simply read the HPCC documentation: http://icl.cs.utk.edu/hpcc/ -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
