Subject: Re: [OMPI users] users Digest, Vol 2339, Issue 5
From: Andrea Negri (negri.andre_at_[hidden])

Hi, Gus and John,

my code (zeusmp2) is a F77 code ported in F95, and the very first time
I have launched it, the processed disappears almost immediately.
I checked the code with valgrind and some unallocated arrays were
passed wrongly to some subroutines.
After having corrected this bug, the code runs for a while and after
occour all the stuff described in my first post.
However, the code still performs a lot of main temporal cycle before
"die" (I don't know if thies piece of information is useful).

Now I'm going to check the memory usage, (I also have a lot of unused
variables in this pretty large code, maybe I shoud comment them).

uname -a returns
Linux cloud 2.6.9-42.0.3.ELsmp #1 SMP Thu Oct 5 16:29:37 CDT 2006
x86_64 x86_64 x86_64 GNU/Linux

ulimit -a returns:
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited
pending signals (-i) 1024
max locked memory (kbytes, -l) 32
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 36864
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited

I can log on the logins nodes, but unfortunately the command ls
/var/log/messages return
acpid cron.4 messages.3 secure.4
anaconda.log cups messages.4 spooler
anaconda.syslog dmesg mpi_uninstall.log spooler.1
anaconda.xlog gdm ppp spooler.2
audit httpd prelink.log spooler.3
boot.log itac_uninstall.log rpmpkgs spooler.4
boot.log.1 lastlog rpmpkgs.1 vbox
boot.log.2 mail rpmpkgs.2 wtmp
boot.log.3 maillog rpmpkgs.3 wtmp.1
boot.log.4 maillog.1 rpmpkgs.4 Xorg.0.log
cmkl_install.log maillog.2 samba Xorg.0.log.old
cmkl_uninstall.log maillog.3 scrollkeeper.log yum.log
cron maillog.4 secure yum.log.1
cron.1 messages secure.1
cron.2 messages.1 secure.2
cron.3 messages.2 secure.3

so, the log should be in some of these files (I don't have read
permission on these files). I'll contact the admin for that.
