LIKWID - Like I Knew What I'm Doing
LIKWID.jl is a Julia wrapper for the performance monitoring and benchmarking suite LIKWID. It is an effort by the Paderborn Center for Parallel Computing (PC²) and, originally, the MIT JuliaLab.
Installation
Prerequisites:
- You must have
likwidinstalled (see the build & install instructions). - You must be running Linux. (LIKWID doesn't support macOS or Windows.)
LIKWID.jl is a registered Julia package. Hence, you can simply add it to your Julia environment with the command
] add LIKWIDLIKWID.jl vs LinuxPerf.jl
As per default (and recommendation) LIKWID(.jl) uses a custom access daemon to monitor hardware performance counters. In contrast, LinuxPerf.jl uses Linux's perf_events. However, it is possible to make LIKWID use perf_events as an alternative (inferior) backend. See here for more information.
