Hi all,
a user has asked how he can speed up this matrix operations in R and I
have noticed that the R in EasyBuild that uses the intel toolchain (e.g.
R-3.4.4-intel-2018a-X11-20180131.eb) is only linked against the
sequential MKL, although R itself is single-threaded, so it might make
sense to use the threaded MKL instead.
I also tried the foss version and here the matrix operations are done in
parallel because OpenBLAS uses multiple threads. But not with MKL.
Is this intentional? if yes, why so? What do I have to change to install
R with the multithreaded MKL?
Thanks,
Maik
