ELPA not working (toolchain build)

[Nicholas Winner]

Hello devs,

I have built CP2K 8.2 on a new machine recently, and ELPA seems to not be built properly.

While everything built without error messages, when I run geometry optimization on this cluster, the code hangs after the first force eevaluation, which is where ELPA is called for the BFGS algorithm. When I specify "preferred_diag_library sl" in my input file, the issue goes away. So I know it is something to do with ELPA.

I used the cp2k toolchain to install ELPA (v2020.11.001). Is it possible that its the ELPA version?

Any help is appreciated. I can use scalapack instead of ELPA for now, but it would be nice to have it working properly.

I have attached the makefile I used for cp2k if that's important.
