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 →
AMD released new Ryzen processors today. Phoronix published an article that benchmarked these processors. Anand Tech also published a review. TechReport also wrote a review. The posting is *not* measured on these new processors. Instead, it looks at dissecting the … Continue reading →
There was an article posted on phoronix comparing several Linux servers including POWER9, Intel and AMD EPYX. Analysis for this article was minimal; so in this post I dug in a bit more on characteristics of the benchmarks of what … Continue reading →
I kicked off a quick run through >100 Phoronix tests to get a quick profile and overall assessment, results from table below. A few items noted: Some of the tests didn’t run, most likely because they didn’t completely install or … Continue reading →
Kicked off a run with the Phoronix CPU suite using likwid-perfctr. Benchmarks that were single-threaded were pinned to a single CPU, others to all CPUs. #!/bin/bash likwid-perfctr -a | tail +3 | awk ‘{ print $1 }’ | while read … Continue reading →
As one of the first steps inpriming the pump for Phoronix benchmarks, I ran the wspy program on 21 candidate CPU benchmarks. My goal was to start with a rough characterization, e.g. single-threaded vs. multi-threaded or cpu-bound vs not. #!/bin/bash … Continue reading →
Below is a table that summarizes installation and run status of the Phoronix Test Suite CPU suite. Some background context of how this fits and where I hope to head from here… Where I’d like to head is comparing micro-architectural … Continue reading →
Created a simple monitoring tool named wspy for workload spy. Source is hosted at http://www.github.com/mvermeulen/wspy This is a wrapper program that collects data as the program runs. The initial program has two data collectors: trace – which uses the ftrace … Continue reading →
The likwid performance monitoring and benchmarking suite has multiple tools including: likwid-topology – print thread, cache and NUMA topology likwid-pin – pin threaded applications to processors likwid-bench – micro-benchmarking application likwid-agent – monitoring agent for hardware performance counters As of … Continue reading →
