CPU Stresstest

stresstest_cpu(core_or_cores)

Run a CPU stress test (matrix multiplication) on one or multiple CPU cores, as specified by the positional argument. If no argument is provided (only) the currently active CPU core will be used.

Keyword arguments:

• duration: stress test will take about the given time in seconds.
• dtype (default: Float64): element type of the matrices
• size (default: floor(Int, sqrt(L2_cachesize() / sizeof(dtype)))): matrices of size (size, size) will be used
• verbose (default: true): toggle printing of information
• parallel (default: true): If true, will (try to) run each CPU core test on a different Julia thread. Make sure to have enough Julia threads.
• threads (default: nothing): If parallel == true, this argument may be used to specify the Julia threads to use.
