To make sure CPUSummary 1.11 and newer are using Hwloc
, you may want to run
julia> using CPUSummary
julia> CPUSummary.use_hwloc(true);
which will hopefully enable accurate hardware information. This is the default, so it should typically be unnecessary.
Octavian.jl is a multi-threaded BLAS-like library that provides pure Julia matrix multiplication on the CPU, built on top of LoopVectorization.jl.
Please see the Octavian documentation.
Octavian dropped 32bit Julia support. See PR#157. If you're interested in restoring it, please file a PR to fix failing tests.
You can run benchmarks using BLASBenchmarksCPU.jl:

julia> rb = runbench(sizes = logspace(10, 1_000, 200)); plot(rb, displayplot = false);
