hi everyone

I have compiled VASP successfully just by commenting out SCALAPACK.
but I do not understand the difference betwixt LAPACK and SCALAPACK

thank you so much

SCALAPACK stands for Scalable LAPACK. It should scale better when running large jobs across distributed memory systems, such as a cluster of machines connected via ethernet.

If all your jobs run on a single machine you can safely ignore SCALAPACK.
