[OMPI users] compilation application with openmpi question

Hi, I have installed openmpi on my machine and tested with some simple programs such as ring and fpi. Everything works. When I tried to compile my application, I got the following: /work/wdx/ptmp/openmpi/openmpi-1.3.2/lib/libotf.a(OTF_File.o): In function `OTF_File_open_zlevel':

Re: [OMPI users] compilation application with openmpi question

Hmmmthose appear to be vampirtrace functions. I suspect they will have to fix it. For now, you can work around the problem by configuring with this: --enable-contrib-no-build=vt That will turn the offending code off. Ralph On Fri, May 1, 2009 at 9:07 AM, David Wong

Re: [OMPI users] MPI processes hang when using OpenMPI 1.3.2 and Gcc-4.4.0

So far, I'm unable to reproduce this problem. I haven't exactly reproduced your test conditions, but then I can't. At a minimum, I don't have exactly the code you ran (and not convinced I want to!). So: *) Can you reproduce the problem with the stand-alone test case I sent out? *) Does the

[OMPI users] HPL with OpenMPI: Do I have a memory leak?

Hi OpenMPI and HPC experts This may or may not be the right forum to post this, and I am sorry to bother those that think it is not. I am trying to run the HPL benchmark on our cluster, compiling it with Gnu and linking to GotoBLAS (1.26) and OpenMPI (1.3.1), both also Gnu-compiled. I have got

Re: [OMPI users] HPL with OpenMPI: Do I have a memory leak?

If you are running on a single node, then btl=openib,sm,self would be equivalent to btl=sm,self. OMPI is smart enough to know not to use IB if you are on a single node, and instead uses the shared memory subsystem. Are you saying that the inclusion of openib is causing a difference in behavior,

Re: [OMPI users] HPL with OpenMPI: Do I have a memory leak?

Hi Gus, For single node runs, don't bother specifying the btl. Openmpi should select the best option. Beyond that, the "80% total RAM" recommendation is misleading. Base your N off the memfree rather than memtotal. IB can reserve quite a bit. Verify your /etc/security/limits.conf limits

[OMPI users] Checkpointing configuration problem

Dear all, I am trying to install openmpi 1.3 on my laptop. I successfully installed BLCR in /usr/local. When installing openmpi using the following options: ./configure --prefix=/usr/local --with-ft=cr --enable-ft-thread --enable-MPI-thread --with-blcr=/usr/local I got the

Re: [OMPI users] Checkpointing configuration problem

Try replacing "--enable-MPI-thread" with "--enable-mpi-threads". That should fix it. -- Josh On May 1, 2009, at 4:17 PM, Kritiraj Sajadah wrote: Dear all, I am trying to install openmpi 1.3 on my laptop. I successfully installed BLCR in /usr/local. When installing openmpi

Re: [OMPI users] Problem with Filem

This typically this means that one or more of the rcp/scp or rsh/ssh commands failed. FileM should be printing an error message when one of the copy commands fail. Try turning up the verbose level to 10 to see if it indicates any problems: -mca filem_rsh_verbose 10 Can you send me the MCA

Re: [OMPI users] HPL with OpenMPI: Do I have a memory leak?

Hi Ralph Thank you very much for the prompt answer. Sorry for being so confusing on my original message. Yes, I am saying that the inclusion of openib is causing the difference in behavior. It runs with "sm,self", it fails with "openib,sm,self". I am as puzzled as you are, because I thought the

Re: [OMPI users] HPL with OpenMPI: Do I have a memory leak?

Gus - Open MPI 1.3.0 & 1.3.1 attempted to use some controls in the glibc malloc implementation to handle memory registration caching for InfiniBand. Unfortunately, it was not only bugging in that it didn't work, but it also has the side effect that certain memory usage patterns can cause the

Re: [OMPI users] HPL with OpenMPI: Do I have a memory leak?

Hi Jacob Thank you very much for the suggestions and insight. On an idle node MemFree is about 15599152 kB (14.8GB). Applying the "80%" rule to it, I get a problem size N=38,440. However, the HPL run fails with the memory leak problem even if I use N=35,000, with openib among the MCA btl

Re: [OMPI users] HPL with OpenMPI: Do I have a memory leak?

Hi Brian Thank you very much for the instant help! I just tried "-mca btl openib,sm,self" and "-mca mpi_leave_pinned 0" together (still with OpenMPI 1.3.1). So far so good, it passed through two NB cases/linear system solutions, it is running the third NB, and the memory use hasn't increased.

Re: [MTT users] Splitting build and run phases

At ORNL, I do this (when I have time to run MTT and time to check the results). What I do is set up my script to check to see if it is in a batch job. If so, it runs the tests, like so: mtt --verbose\ --print-time
