I’ve analyzed the gromacs computational chemistry application using three sample workloads and created an analysis page for the results as well as added them to the overall workload summary. This post describes a few higher-level takeaways I have from the … Continue reading →
I downloaded and built gromacs from www.gromacs.org and used the 5.1.5 version because some of the tutorials/benchmarks still refer to this older version. This post documents steps I used to run gromacs 5.1.5 on a Ryzen processor.
Continue reading →This post documents steps I used to build, install and run gromacs. gromacs is a molecular dynamics package for simulating proteins, lipids and nucleic acids. It seems to be one of the more common HPC applications. My interest is less … Continue reading →
Intel processors provide a useful set of performance counters for doing topdown analysis, particularly at the first topdown level. This first level asks questions in the following hierarchy: Is a Uop dispatched? If yes, is it retired? If yes –> … Continue reading →
Phoronix posted an article comparing 28 desktop CPUs. This post reviews some of the workloads that were used.
Continue reading →On the upper left of the web site is now an item labeled “phoronix”. Clicking there returns a table with a long list of Phoronix benchmarks. For each I’ve recorded the description, scores when running on my Intel reference system, … Continue reading →
Phoronix posted an article comparing 15 different OS versions. This posting doesn’t reproduce the measurements, but instead looks at overall summaries made as well as looks at the benchmarks being used for comparisons.
Continue reading →Phoronix posted an article comparing OpenSuSE leap 15, leap 42.3 and tumbleweed. I don’t have these operating systems on my benchmark system, but make the following notes about what the benchmarks are measuring.
Continue reading →May coming to a close, useful to take stock of where analysis is at as well as next steps. I was cycling a good portion of May. The other parts were most focused on adding benchmark analysis needed for some … Continue reading →
I have updated the topdown wrapper script to add some additional cache statistics for level 3 backend related information. I have also added a -x option to display some rusage information.
