Sorry for posting the second question i a row but I have encountered serious problems running a geometry optimization in parallel mode.
I think the problem is with the rdgrad module because when I start a calculation in parallel I crashes with the following message in the slave1.output:
this is node-proc. number 1 running on node
bx10
the total number of node-proc. spawned is 7
parallel platform: SMP or SMP like systems
call pa_barr(90)
data group $actual step is not empty
due to the abend of ridft
check reason for abend ...
use the command 'actual -r' to get rid of that
CONTRL dead = actual step
rdgrad ended abnormally
The calculation start just fine an the first ridft-step is performed in parallel without error (I check the running task on the node just after submitting the job)
but then it crashes with the message above. Strange is that I have running calculation with with 3 or 4 cpu-cores in use which seem to run just fine. I the above case
i used 7 cpu-cores.
Anyone know where my problem is?
Regards Jan

in addition:
I test the same job above with 4 cores (3 +1 server task) and there was no error. But when I select more than 4 it alway crashes
with the message above.
