Hi Exequiel,
The reason why the ScaLAPACK easyblock only considers a couple of
libraries that provide LAPACK functionality is because it needs to know
how to define the BLASLIB and LAPACKLIB build options for the LAPACK
library being used...
The easyblock can not guess it should link to a LAPACK library it
doesn't know about, it would need be enhanced so it does know what to do.
The ScaLAPACK easyblock was reworked a bit recently, see
https://github.com/hpcugent/easybuild-easyblocks/pull/1014/files, but it
still only considers (netlib) LAPACK, ACML and OpenBLAS as libraries
that provide LAPACK functionality (it does know about ATLAS and GotoBLAS
as libraries that can be used together with (netlib) LAPACK).
Are there any other BLAS or LAPACK libraries you would like to see
supported by the ScaLAPACK easyblock?
regards,
Kenneth

It is different to dependencies.
If you look at line 73 in
https://github.com/hpcugent/easybuild-easyblocks/blob/master/easybuild/easyblocks/s/scalapack.py,
there is this line:
deps =[("LAPACK", "ACML", "OpenBLAS")]
And this variable is used for checking compulsory modules/components.
Cleary, as these three components are hard-coded, you can do nothing
in the EasyConfig file.
In an older version in
https://github.com/hpcugent/easybuild-easyblocks/blob/v1.1.0/easybuild/easyblocks/s/scalapack.py:
deps =[("LAPACK", "ACML")]
That is my question, is there any reason for?
Cheers

Hi,
Is there any reason for having hardcoded ScaLAPACK to use
OpenBLAS?
From EB_ScaLAPACK.py:
deps = [("LAPACK", "ACML", "OpenBLAS")]
The problem is I want to build goalf toolchain, but it is
contradictory OpenBLAS and ATLAS.
The list of dependencies here are optional, not all of these are
required, just *one* of them is.
To build and install ScaLAPACK, one of these should be available
(since these provide LAPACK functionality).
If you want to install ScaLAPACK on top of ATLAS, you also need to
list LAPACK as a dependency, as we do in
https://github.com/hpcugent/easybuild-easyconfigs/blob/master/easybuild/easyconfigs/s/ScaLAPACK/ScaLAPACK-2.0.2-gompi-1.5.12-ATLAS-3.10.1-LAPACK-3.4.2.eb
