I have a program which uses MPI::Comm::Spawn to start processes on
compute nodes (c0-0, c0-1, etc). The communication between the
compute nodes consists of ISend and IRecv pairs, while communication
between the compute nodes consists of gather and bcast operations.
After executing ~80 successful l
Hello,
I use a bioinformatics software called MicroTar to do some work. But it
seems that it dosen't finish well.
MicroTar parallel version was terminated after 463 minutes with following
error messages:
[gnode5:31982] [ 0] /lib64/tls/libpthread.so
Hi All,
I made some tests with a dummy "ping" application. Some memory problems
occurred. On these tests I obtained the following results:
1) OpenMPI (without FT):
- delaying 1 second to send token to other node: orted and
application size stable;
- delaying 0 seconds to send token to o
Leonardo,
You are exactly correct. The CRCP module/component will grow the
application size probably for every message that you send or receive.
This is because the CRCP component tracks the signature {data_size,
tag, communicator, peer} (*not* the contents of the message) of every
messag

I have verified that maui is killing the job. I actually ran into
this with another user all of a sudden. I don't know why its only
effecting a few currently. Here's the maui log extract for a current
run of this users' program:
---
[root@aeolus log]# grep 2120 *
maui.log:05/29 09:01:45
I don't know much about Maui, but these lines from the log seem
relevant:
-
maui.log:05/29 09:27:21 INFO: job 2120 exceeds requested proc
limit (3.72 > 1.00)

Hi,
I'm trying to run my program in my environment and some problems are
happening. My environment is based on PVFS2 over NFS (PVFS is mounted
over NFS partition), OpenMPI and Ubuntu. My program uses MPI-IO and
BZ2 development libraries. When I tried to run, a message appears:
File locking failed
Well don't run like this. Have PVFS have NFS, don't mix them like
that your asking for pain, my 2 cents.
I get this error all the time also, you have to disable a large
portion of the caching that NFS does to make sure that all MPI-IO
clients get true data on the file they are all trying t
HI,
I am in one of your MPI instructional videos and have a question. You said
to make sure
the registered memory ulimit is set to unlimited. I type the command
"ulimit -a" and don't
see a registered memory entry. Is this maybe the same as "max locked
memory"?
Or can you tell me where to check

Hi,
I'm already using "noac" option on my /etc/fstab but this error is
still happening. I need to put this in another file ?

That I don't know, we use lustre for this stuff now. And our users
don't use parallel IO, (though I hope to change that).
Sorry can't help more. I would really use 'just' pvfs2 for your IO.
The other reply pointed out you can have both and not use NFS at all
for your IO but leave it mounte

How mpi handles the host string passed in the info argument to
mpi_comm_spawn() ?
if I set host to:
"host1,host2,host3,host2,host2,host1"
then ranks 0 and 5 will run in host1, ranks 1,3,4 in host 2 and rank 3 in
host3?
17 matches
