Greetings,
Redhat 7.3
LAM 7.0
I have an interesting (to me) problem.
Recon runs fine, I can lamboot without problem, I can run the
lamtests and they indicate no problem.
However, when I run the plain vanilla hello-world application
from /usr/share/doc/lam-7 only the local node and the
master produce output. If I run it on the master (where I launch
lamboot from, the origin) only the master produces output.
In this particular case I have 8 systems in the boot schema
and I can see the program running in the process table of
the systems, but I only get output from the system where I
launched the job from.
For example:
lamboot schema---------
univac # the master
node002 cpu=2
node003 cpu=2
node004 cpu=2
node005 cpu=2
node007 cpu=2
node008 cpu=2
node009 cpu=2
Command line on the master--------
[galitz_at_univac hello]$ mpirun C hello
Hello, world! I am 0 of 15
Command line on node002-----------
[galitz_at_node002 hello]$ mpirun C hello
Hello, world! I am 2 of 15
Hello, world! I am 1 of 15
Hello, world! I am 0 of 15
Command line on node005-----------
[galitz_at_node005 hello]$ mpirun C hello
Hello, world! I am 7 of 15
Hello, world! I am 8 of 15
Hello, world! I am 0 of 15
lamnodes from node005--------------
[galitz_at_node005 hello]$ lamnodes
n0 univac:1:origin
n1 node002:2:
n2 node003:2:
n3 node004:2:
n4 node005:2:this_node
n5 node007:2:
n6 node008:2:
n7 node009:2:
