Hello Antoine, Nikolay, The selection of a much performant BLAS / LAPACK implementation is very system-dependent and I don't want to maintain something not standard / widely deployed on Linux distributions. As a reference, the current Fedora status is to link against the library used at build-time [1]. Nicolay pointed on a similar link for Debian which use /etc/alternatives to let the user select a library.
Currently, it is still possible to enforce a specific BLAS/LAPACK library using LD_PRELOAD (LD_PRELOAD=/usr/lib64/libopenblaso.so.0 bin/scilab for example). However it could not be enforced within Scilab stock version even it is known [2] that Atlas or OpenBLAS will slightly improve Scilab speed as it is highly system / user dependent choice.
