A guess, which is the best we can do at the moment. See if you can ssh
into the nodes without the .local at the end and if you can then create a
.machines file without the .local and try x

I did your suggestions but unfortunately I have no success yet.

a) Use as .machines file

The number of these will tell you how many cores you have (and it
could be twice the true number if hyperthreading is on).

a) This should report the total number of physical CPUs:

Dear Marks and Fecher,
I checked the cpu and it is 4 cores without hyperthread. I am running the
tasks in console not with w2web. I checked my dns and it is ok as you can

PING
Sorry, no. The error report you are getting implies a communication error
and ping wont fully check this. Run the ssh command at the end of your
output just at the terminal, with the appropriate exec. It is either this,
or somehow you are losing the sed replacement of the executable name.

thanks a lot for the answer. Let's to my comments

It is hard to know as you have not provided us with enough
information, so we can only guess. Most likely is that you have setup
the problem wrong, for instance bad RMTs, bad

This will run 3 tasks each using mpi with 8 cores on each computer. If

Dear P. Blaha,
sorry but I still have problem with wien in parallel mode.
I try set up the parallel options as you suggested and I got the error

It is hard to know as you have not provided us with enough
information, so we can only guess. Most likely is that you have setup
the problem wrong, for instance bad RMTs, bad case.in1c or other. Read
the file lapw1.error to see if it has anything, and also the various
output files. Beyond this:
