[petsc-users] MKL installation can't be used to configure PETSc

[Yongzhong Li]

Thank you Satish!

I think I find the issue, the MKLROOT should be one of the subdirectory for the previous address.

Another question, do you know if PETSc can be configured with AMD AOCL https://urldefense.us/v3/__https://www.amd.com/en/developer/aocl.html__;!!G_uCfscf7eWS!dPM5PLRb-ePnG4HHZzs-Z7FUTkod4fvyBeYnsMy2Kg11pRg4gTAZ2D7J7w0Cx5UbezSeYC5tDcB2GqbdDP2VwiDJ-vwREa2E1Ns$  as the BLAS and LAPACK.

Thanks,
Yongzhong

Are you sure you are providing the correct path?

Normally you should see something like the following [wrt the dir you specify to --with-blaslapack-dir]

>>>
balay at cg:~$ env |grep MKL
