I agree that the "R Installation and Administration" guide statement about FlexiBLAS needs an update.

Hi, R has been built against FlexiBLAS in rawhide [1, 2]. These are the R packages that need to be rebuilt: R-ape-0:5.4-2.fc33.x86_64 R-expm-0:0.999.4-7.fc33.x86_64 R-gee-0:4.13.20-4.fc33.x86_64 R-gss-0:2.2.2-3.fc33.x86_64 R-igraph-0:1.2.5-3.fc33.x86_64 R-msm-0:1.6.8-5.fc33.x86_64 R-preprocessCore-0:1.50.0-4.fc33.x86_64 R-qtl-0:1.46.2...

I've not worked changing underlying computational infrastructure, but developers who do might want to use ideas from FlexiBLAS. Apologies in advance if this is well-known.

...this in 83986 [1] needs a fix in Lapack.c: if (dladdr((void *) F77_NAME(ilaver), &dl_info)) { char buf[PATH_MAX+1]; char *res = realpath(dl_info.dli_fname, buf); if (res) { SEXP nfo = R_NilValue; if (strstr(res, "flexiblas")) nfo = R_flexiblas_info(); if (isNull(nfo)) nfo = mkChar(""); ans = ScalarString(nfo); break; } } It will always return an empty string except for flexiblas. I assume this...

...essing the same cache line. (descriptors already grew to 16 bytes, do we need more?) - was playing around with the idea of different ring types for different devices e.g. scsi, net. starting with generic information then comes protocol specific data. Ilya agrees. length of descriptor would be flexibla by adding a descriptor length field. How to continue / TODOs: - do benchmarking with bigger frame sizes on fast enough NICs - turn prototype code into a RFC series (work in progress) - more people interested to join monthly meetings Open questions: - Do we need an (optional) completion rin...

...vector for argument what. A new generic, nameOfClass(), is called to resolve the class name from what. This supports experimenting with alternative object systems. Based on contributions by Tomasz Kalinowski in PR#18485. * Detection of BLAS/LAPACK in use (sessionInfo()) with FlexiBLAS now reports the current backend. * The "data.frame" method for subset() now warns about extraneous arguments, typically catching the use of = instead of == in the subset expression. * Calling a:b when numeric a or b is longer than one may now be made int...
