Dear experts,
I try to install LAM in SGI-MPT machine. 4 core in master node and 32 core in execution nodes, respectively Intel(R) Xeon(R) CPU X5272 @ 3.40GHz. Resulting in the following problem:
If I only execute aplication only for running in master node, it works, ie:
agung_at_ptmlxclus:~/bin/lam-7.1.4/examples/hello> mpirun -np 4 hello
Hello, world! I am 0 of 4
Hello, world! I am 1 of 4
Hello, world! I am 2 of 4
Hello, world! I am 3 of 4
agung_at_ptmlxclus:
But if I execute by including any execution nodes, the process freeze, ie:
agung_at_ptmlxclus:~/bin/lam-7.1.4/examples/hello> mpirun -np 8 hello
<freeze>
(and after pressing Ctrl-C 3 times, out the following:)
********************* WARNING ***********************
This is a vulnerable region. Exiting the application
now may lead to improper cleanup of temporary objects
To exit the application, press Ctrl-C again
********************* WARNING ************************
agung_at_ptmlxclus:
freezing also occurs in tping (success in the first time, but freeze after trying parallel execution), lamhalt and lamexec command (lamexec only show the name of master node). I tried to google and find the same problem in
http://www.lam-mpi.org/MailArchives/lam/2007/05/13152.php
But the problem written there wasn't resolved yet. Could anyone help me to solve this please?
Thanks in advance,
Agung
