Re: [OMPI users] v1.3: mca_common_sm_mmap_init error

I have not seen this before. I assume that for some reason, the shared memory transport layer cannot create the file it uses for communicating within a node. Open MPI then selects some other transport (TCP, openib) to communicate within the node so the program runs fine. The code has not

Re: [OMPI users] Issue with PBS Pro

On a Torque system, your job is typically started on a backend node. Thus, you need to have the Torque libraries installed on those nodes - or else build OMPI static, as you found. I have never tried --enable-mca-static, so I have no idea if this works or what it actually does. If I want

Re: [OMPI users] Joe Griffin: "Re: Cannot compile on LinuxItanium system"

Tony, I had tried just the compile line using -O0, but it did not help. The last assembly I actually wrote was for a Cray Y-MP I think, so I don't intend on delving into that. Sorry I couldn't be more help. I do have access to what I call a Frankenstein Cluster of Itaniums ( different

Re: [OMPI users] openmpi over tcp

It is quite likely that you have IPoIB on your system. In that case, the TCP BTL will pickup that interface and use it. If you have a specific interface you want to use, try -mca btl_tcp_if_include eth0 (or whatever that interface is). This tell the TCP BTL to only use the specified

Re: [OMPI users] Joe Griffin: "Re: Cannot compile on Linux Itanium system"

Joe, Intel recommends to set all of the compile flags, like CCFLAGS, to -O2. Other than than, we are doing nothing different than what Intel recommends. When I set CCAS=ias, ./configure does not make it through the Assembler stage. When I set CCAS=ias and CASFLAGS= (I am setting it to

[OMPI users] openmpi over tcp

Hi All, I'm doing some tests on a small cluster with gigabit and infiniband interconnects with openmpi and I'm running into the same problem as described in the following thread: http://www.open-mpi.org/community/lists/users/2007/04/3082.php Basically even if I run my test with: mpirun --mca btl

Re: [OMPI users] Compilers

Hi Ray, If you look at the Intel Series 11 compilers there are warnings about mixing various types of compilers although the Series 11 C++ Release Notes do talk about Eclipse Integration and C/C++ Development tools. I think that I will get in touch with Intel before I do much more. Can

Tony, Well, I was hoping to get you a good data point, but instead I reconfirmed the error you got: tar -xzf openmpi-1.3.tar.gz setenv CC icc setenv CXX icc setenv F77 ifort setenv FC ifort cd openmpi-1.3 setenv LD_LIBRARY_PATH /opt/intel/cc/10.1.012/lib ./configure

[OMPI users] Issue with PBS Pro

Hi, I am trying to run with Open MPI 1.3 on a cluster using PBS Pro: pbs_version = PBSPro_9.2.0.81361 However, after compiling with these options: ../configure --prefix=/home_nfs/parma/x86_64/UNITE/packages/openmpi/1.3-intel10.1-64bit-dynamic-threads CC=/opt/intel/cce/10.1.015/bin/icc

[OMPI users] Using compiler_args in wrappers with Portland Group Compilers

I'm trying to use the compiler_args field in the wrappers script to deal with 32 bit compiles on our cluster. I'm using portland group compilers and use the following for 32 bit builds: -tp p7 (I actually tried to use -tp x32 but it does not compile correctly. I think it has something to do

[OMPI users] Pinned memory

Dear OpenMPI Developer, i have a doubt regards mpi_leave_pinned parameter. Suppose i have a simple for: for( int i=0; i< 100; i++) MPI_Reduce(a, b, ...) My question is: if i set mpi_leave_pinned= 1, buffer memories are pinned in the entire process, or just into the for cycle? When the

[OMPI users] Rmpi and LAM

I'm using R on a Ubuntu 8.10 machine, and, in particular, quite a lot of papply calls to analyse data. I'm currently using the LAM implementation, as it's the only one I've got to work properly. However, while it works fine on one PC, it fails with the error message Error in mpi.comm.spawn(slave
