[CP2K:8615] proplem with cp2k built with intelmpi

[Mariella Ippolito]

Dear Iain,
I built again the code (trunk version) using MKL 2017.0.098 and your arch 
file: unfortunately I obtain the same results (Electronic density on 
regular grids = NaN).
I read that some other users experienced similar problem but in their case 
the use MKL 2017.0.098 seem to solve the problem.
Some other suggestion?

Thank you,
Mariella
