[Nek5000-users] Linking other libs to Nek, e.g. ESSL in Blue Gene

[nek5000-users at lists.mcs.anl.gov]

Hi Aleks,

I agree, but that does unfortunately not answer my question. Let me give an example:
I want to call the routine

call dgeev (..,..,..)

in usrchk. But where do I have to link the ESSL lib?
Something like -lessl needs to be added somewhere in the makefiles?

Thanks a lot, Joerg.

Hi Joerg,

The easiest place to call your routines will be in userchk since it is called by every rank every time step including istep=0

Best.
Aleks

Dear Neks,

I have a short technical question. For our post processing analysis of turbulent convection
we want to use routines from ESSL Library.

Where is the best place to include the link command to this library into the makefile or makenek?

Thanks in advance, Joerg.
