from <code>http://www.ce.uniroma2.it/psblas</code>; indeed, all the

<P>
|

Please note that all the libraries listed so fare (BLAS, MPI, BLACS,
|

PSBLAS) must have Fortran interfaces compatible with the MLD2P4;
|

Please note that the four previous libraries must have Fortran

interfaces compatible with MLD2P4;

usually this means that they should all be built with the same

compiler.
