Follow-up Comment #15, bug #45890 (project octave): I get numbers that are very similar to Rik's (oldish Xeon). t = 3.23645 3.28782 3.28776 3.32183 3.19292 0.30566 0.32043 0.32495 0.30760 0.31066 2.51998 2.52266 2.61129 2.49808 2.45491 0.88806 0.88445 0.89706 0.85344 0.85099 0.42461 0.41365 0.44222 0.41224 0.39768 2.97178 3.02007 3.04358 2.98643 2.97333 I also noticed that it is all running single-thread (though I expected A*x and A'*x to utilize multithreaded blas). (this is with 4.4.1) Dmitri. -- _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?45890> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
