It seems that reproducibility across systems is also an issue with multithreaded BLASes: https://hal.archives-ouvertes.fr/hal-01202396/file/exblas.pdf On Sun, Dec 17, 2017 at 11:50 AM, Keith O'Hara <keith.ohara at nyu.edu> wrote: > On point 1): > > The standard approach seems to favor the reference BLAS for reasons other > than speed. > > For example, vecLib, Apple's multi-threaded BLAS library, is not the &g...

On point 1): The standard approach seems to favor the reference BLAS for reasons other than speed. For example, vecLib, Apple's multi-threaded BLAS library, is not the default choice for macOS binaries due to concerns about 'precision'. See: https://cloud.r-project.org/bin/macosx/RMacOSX-FAQ.html#Whic h-BLAS-is-used-and-how-can-it-be-changed_003f This doesn't appear to be Mac-

Hi R-devel list, OpenBLAS is readily available for unix-likes: https://cloud.r-project.org/web/packages/gcbd/vignettes/gcbd.pdf However, my questions are: 1) Would R-devel consider using OpenBLAS for the main distribution of R for all platforms including Windows? 2) If so, would R-devel set the default multi-thread level to the number of (real) cores on a machine? My sense is there're a
