Mail from the MUMPS team:

Bonjour Alexis,

Concernant BLACS et ScaLAPACK, ils peuvent en effet être utiles pour la performance lors du
traitement du dernier complément de Schur, quand on utilise du parallélisme MPI. S'ils ne sont pas installés,
MUMPS essaiera de trouver un peu de parallélisme aussi, mais sans utiliser du 2D block cyclique
et cela peut être un peu moins efficace.

Bonne journée,
le groupe MUMPS
