@laborat, the recent (two days old) community/intel-mkl package lacks a lot of content from the split package.

Please keep on using aur/intel-mkl as part of aur/intel-parallel-studio-xe until the relevant scripts are ported to community.

Also, as a general note, those with Ryzen processors could obtain even better performance by setting an environment variable. Please see https://www.reddit.com/r/MachineLearning/comments/f2pbvz/discussion_workaround_for_mkl_on_amd/

R doesn't work after latest upgrades. There is a problem with package "icu" or "lib32-icu".

[eduardo@manjaro-linux lib]$ R
/usr/lib64/R/bin/exec/R: error while loading shared libraries: libicuuc.so.51: cannot open shared object file: No such file or directory

To speed up some more commonly used basic math functions (e.g. log,root,trigonometric) I have tested linking against Intel's 'libimf' (included in intel-mkl) and AMD's 'libamdlibm' (in AUR: amdlibm). Use of amdlibm resulted in substantial speedups compared to libm-218, libimf also showed speedups, but much less substantial (at least on the (AMD) CPU I had used for testing). For both libraries some functions showed slight slowdowns compared to libm as well. It would be great to get some more input from users with other processors to decide if linking against libimf or libamdlibm by default makes sense. You can try out the libraries by preloading them (LD_PRELOAD).

aberkoke, I have never compared the performance of R compiled with Intel's compilers to R compiled with the GNU compiler collection. I would not expect a substantial difference in most cases, but that might vary dependant on the type of CPU and what instructions R needs to perform.

But if you could try it out, that would be great! It should be possible to make different versions with different compilers and compiler flags by playing with the CC, CFLAGS etc. environment variables before building the package.

Thanks for the maintenance of the pagacke! What do you think about compile R with intel icc? better performance?

Updated to 3.0.2. If there are file conflicts because of updated packages, just delete the 3.0.1 files. Please inform me of any bugs.

Updated to 3.0.1

Updated to 2.15.1, I am not sure if I provided the MKL_ROOT correctly, comments welcome

CRAN makes it difficult to allow a package to stay slightly out of date (I can't devote the time necessary) and it's much easier to use R's built-in installation program, so I'm disowning this package. Sorry!
