Hello again, The "oob_stress" program runs cleanly on each of

Hello again, The "oob_stress" program runs cleanly on each of
the two test nodes bro127 and bro128 as shown below. Would
you say this rules out a problem with the network and switch,
or is there another test program(s) that should be run next ?
o eth0 and eth2: without plm_base_verbose

It's the failure on readv that's the source of the trouble. What
happens if you only if_include eth2? Does it work then?
Still hangs, details follow ... tx!
o Using only eth2 with verbosity gives:

The most common cause of this problem is a firewall between the
nodes - you can ssh across, but not communicate. Have you checked
to see that the firewall is turned off?
Turns out some iptables rules (typical on our clusters) were act
1) When openmpi programs run across multiple nodes they hang
rather quickly as shown in the mpi_test example below. Note
that I am assuming the initital topology error message is a
separate issue since single node openmpi jobs run just fine.

Using 1.3a1r18423 built against blcr 0.7.1 but cannot get
ompi-restart to start processes on machinefile hosts. No
useful information shown in /var/log/messages on master or
intended hosts. Disabling prelinking doesnt help either.
ie) All processes start on the host which ompi-restart
is execute
Hi, I am trying to use the latest release of v1.3 to test with BLCR
however i just noticed that sometime after 1.3a1r18423 the standard
mpich sample code (cpi.c) stopped working on our rel4 based myrinet
gm clusters which raises some concern.
Please find attached: gm_board_info.out, ompi_info--a
Thanks. Adding FCFLAGS="-mismatch -w" allowed openmpi-1.1a9r10177
to build this time and i am able to run simple test problems on the
cluster. However, I am unable to run example problems that come with
the Nag Parallel library which we also have in addition to the Nag
f95 compiler. So I just
istake); the fix should show up
in the snapshot tarballs tonight.

Hi
Hi, I'm using the NAGWare Fortran 95 compiler Release 5.0(414), but make
fails as shown in the snippet below. I've attached the config.log,
config.out and make.out files. The system is a dual processor Opteron
server running a 2.6 x86_64 linux kernel and has a myrinet mx based
interconnect which
