We are trying to run NASTRAN on a Scyld beowulf cluster. The license
authorization is provided by a Windows server on the same subnet.
- No problem if the job runs on the master node. Problem is I can only
run it on the master node...
- Job will not run on a compute node. I use the following command.
mach 37% bpsh 5 nast_perl
(nast_perl is a perl script that runs nastran by executing
system "nastran scr=yes nastran_example.bdf"
inside the script.
The compute node is unable to get license authorization. The message
MSC.Nastran V2005.0 (AMD Linux 2.4.21-40.EL.301u0030smp) Tue Oct 9
*** USER FATAL MESSAGE (pgm: nastran, fn: validate_authorize)
authorize=1700 at xxx.xx.xxx.xx (Env: MSC_LICENSE_FILE)
Host "xxx.xx.xxx.xx" is unknown in this network.
The xxx.xx.xxx.xx is the license server on the network. The idea is not
to run Nastran in parallel mode (or a multi threaded version of it),
just run a single instance of it on a compute node. The master node has
I am not much of an admin. But it probably useful to mention the
/etc/nsswitch.conf is configured as:
bootparams: nisplus [NOTFOUND=return] files
ethers: files bproc beo
protocols:files bproc beo
services: files bproc beo
Any pointers on what I should look for?
