[Wien] MPI error

[leila mollabashi]

Dear Prof. Peter Blaha and WIEN2k users,

Thank you for your assistances.

> At least now the error: "lapw0 not found" is gone. Do you understand why
??

Yes, I think that because now the path is clearly known.

>How many slots do you get by this srun command ?

Usually I went to node with 28 CPUs.

>Is this the node with the name  e0591  ???

Yes, it is.

>Of course the .machines file must be consistent (dynamically adapted)

with the actual nodename.

Yes, to do this I use my script.

>When I use “srun --pty -n 8 /bin/bash” that goes to the node with 8 free
cores, and run x lapw0 –p then this happens:
