intel-mkl 2020.0.166-1 no longer has /opt/intel #12

wrt to your helpful script/instructions - it looks like intel-mkl-2020.0.166-1 and the rest of its .deb packages no longer use /opt/intel and instead install everything directly into various standard dirs, which I think makes them visible to compilers w/o needing any env vars.

Moreover the .deb packages no longer include the mklvars.sh script, so now we need to figure out how to set all the different env vars manually for all those projects that expect a gazillion of mkl env vars like: MKL_LIBRARIES MKL_INCLUDE_DIRS MKL_INTERFACE_LIBRARY MKL_SEQUENTIAL_LAYER_LIBRARY MKL_CORE_LIBRARY and fail w/o those preset.

Probably need to fool those with setting MKLROOT=/usr, MKL_LIBRARIES=/usr/lib/x86_64-linux-gnu, etc. But I'm not 100% sure what some of those used to point to.

Ah, and it now automatically redefines BLAS/LAPACK during the package install:

Setting MKL as default BLAS/LAPACK implementation as requested.
update-alternatives: using /usr/lib/x86_64-linux-gnu/libmkl_rt.so to provide /usr/lib/x86_64-linux-gnu/libblas.so (libblas.so-x86_64-linux-gnu) in manual mode
update-alternatives: using /usr/lib/x86_64-linux-gnu/libmkl_rt.so to provide /usr/lib/x86_64-linux-gnu/liblapack.so (liblapack.so-x86_64-linux-gnu) in manual mode

This is during the run of:

sudo apt-get install intel-mkl-full

So we no longer need to set up the file /etc/ld.so.conf.d/mkl.conf ? Good.

stas00 commented 4 years ago

It appears so. It's odd that they made such a major change in the same major version.

eddelbuettel commented 4 years ago

So short of a more formal PR (no need really) should I just comment out lines 27 to 30? Would you be able to test and verify?

stas00 commented 4 years ago

I was hoping you'd do an install of the latest release at some point in the future and see what needs to be changed. I haven't used the previous setup, so I have no point of reference. I only meant to indicate these changes in this issue.

It turns out that the quantum mechanics code GAMESS looks for the mkl libraries in the /opt/intel/ tree, and that is now broken. Intel says that the mkl libraries are installed in /opt/intel/... While I can see the possible benefit of also having them in the other locations, I think it should not also break what would normally be expected from packages that can use it. Could the transition not keep both with a link from the /opt tree to the standard ones?

eddelbuettel commented 3 years ago

You should probably be talking to Intel who produces these .deb files, and/or to the GAMESS people. This is a simple convenience repo with a helper script that was once useful to me. It is in no way official or affiliated with Intel.

Ah, thank you for the clarification.
