Hi everyone,
Just wanted to share some quick baseline benchmark results [3].
I ran LU decomposition on a AMD Ryzen Threadripper 1950x 16C/32T system.
LAPACK is currently plain loop parallel BLAS as far I believe.
And the upstream version of PLASMA uses OpenMP tasks [1].
The colored region is the 95% confidence interval.
Task parallelism seems to scale pretty well on such a small scale benchmark.
I hope work-stealing could improve this even more.
