Damn, I thought it's solved. Even though MPI is now correctly configured, I still obtain the following message:
<gretlcli> *** Warning *** * * gretl is built using OpenMP, but is linked against * OpenBLAS parallelized via pthreads. This combination * of threading mechanisms is not recommended. Ideally, * OpenBLAS should also use OpenMP. </gretlcli> Artur Am 03.06.2017 um 18:28 schrieb Artur Tarassow: > Ok, I've figured out where the MPI library is located.
