[Nek5000-users] Linking ESSL Lib to nek5000

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

Hi Aleks,

just to give a feedback to all.

1/ mpixlf77_r instead of mpixlf77 works successfully.

2/ Including the lib (in this case IBM ESSL Library) works via makenek is also O.K.
In my case (BG/Q):

# linking flags
USR_LFLAGS="-L/bgsys/local/lib -lesslbg"

Thanks once more, Joerg.

Hi Joerg,

Could you try  thread-safe compilers,

mpixlf77_r
mpicc_r

before I start asking around?

Thanks.
Aleks

Hi Aleks,

I followed your suggestion and changed the path in makenek to


# linking flags
USR_LFLAGS="-L/bgsys/local/lib -lesslbg"

This where ESSL lib is found on BG/Q Juqueen in Juelich. When I run makenek, I get
the following error message.

Do you know what went wrong?
Thanks, Joerg.
