Dear lam team,
I am trying on a IBM SP4 at ECMWF to spawn an executable from one
node to another one.
It works with lam 6.5.9 but not with 7.0 . Furthermore I test it on a
cluster of PC where it works with lam 7.0
the strange points is lamboot -v boot_schema works but it just deadlock
at the spawn time during the mpirun -c 1 .driver command.
I am quite confident to the program since it also works on FUJITSU and
NEC SX5 with native implementations.
The idea is to make the driver spawn a block executable where it is
indicated in block.where. and if this file is not there, then the
spawned block stay on the same node that the driver (what we called
intranode and is working).
Hope you should give me some clues
There is 2 athers little points lamhalt start but hang never finishing.
35:> lamhalt
LAM 7.0/MPI 2 C++/ROMIO - Indiana University
The last little point is that mpiexec is not installed
The ecmwf support try tracking the matter and they told me there is
something wrong with their perl
version :
tools/mpiexec/mpiexec -testI get
Can't locate File/Temp.pm in @INC (@INC contains: /usr/opt/perl5/lib/5.6.0/aix

So some module is not found which is needed.
Return to main problem.
