This is not so easy, and also this is probably not the only issue you
have. A few key points:
1) The default mechanism to connect is ssh, as this is the most
common. It is setup when you run configure, but can be changed later.
The expectation if you use ssh is that keyless login is setup (e.g.
OK. If possible try and do a robust patch, i.e. one which is portable.
If you get one please send.
For reference, that call is important in most cases for larger
problems. It is related to the stacksize set for the user (ulimit). If
this is too small large Fortran (and other) programs can crash.
Thank you for your quick reply. I am going to investigate the
parallel_options together with the admins of our cluster.
As for your questions:
a) I am able to correctly generate the .machines file, so at least I
know the nodes on which the calculation takes place.
b) I will experiment
Dear Wien2k users,
I am trying to set up Wien2k on a (mid-size) computation cluster running
an SGE queueing system. Now, I am a bit confused as to how Wien2k spawns
processes for MPI execution. I am used to the scheme, where mpirun takes
care of spawning its processes across the nodes
