Re: [OMPI users] which gcc to compile openmpi with?

The problem is that I am building my entire MPI-based simulator with openmpi wrappers and my simulator code only compiles with gcc-2.95.3...any thought??does openmpi NOT work with 2.95.3?? --- On Wed, 9/24/08, Terry Frankcombe wrote: From: Terry Frankcombe

Re: [OMPI users] which gcc to compile openmpi with?

Both of those are really ancient. Fortran in particular will not work happily with those. Why don't you install something from the current epoch? I run happily with gcc 4.3.2. On Wed, 2008-09-24 at 08:36 -0700, Shafagh Jafer wrote: > which gcc is prefered to compile openmpi with?? gcc-2.95.3

[OMPI users] Crash in code using OMPI 1.2.7 - Debugging assistance sought

Hello. I have a user running a Fortran code that can be built and run on on both 32-bit and 64-bit architectures. When this code is built for the x86-64 machines in our cluster, running on OMPI 1.2.7, it runs fine. However, if we build and run it on 32-bit x86 machines, also running the same

Re: [OMPI users] mca:base:select:( ess) No component selected!

Thank you. I was able to make everything work by using orte_launch_agent and bash's $@ to pass the necessary parameters to orted within my shell script. I needed to add additional paths to my LD_LIBRARY_PATH/PATH variables for other necessary libraries, which is why I was pushing on the

Re: [OMPI users] mca:base:select:( ess) No component selected!

Yes - you don't want to use orte_launch_agent at all for that purpose. What you need to set is an info_key in your comm_spawn command for "ompi_prefix", with the value set to the install path. The ssh launcher will assemble the launch cmd using that info. Ralph On Sep 24, 2008, at 1:28

Re: [OMPI users] mca:base:select:( ess) No component selected!

Yes, your first sentence is correct. I intend to use the unmodified orted, but I need to set up the unix environment after the ssh has completed but before orted is executed. In particular, one of the more important tasks for me to do after ssh connects is to set LD_LIBRARY_PATH and PATH to

Re: [OMPI users] mca:base:select:( ess) No component selected!

Sorry for the miscommunication: The processes are started by my program with MPI_Comm_spawn, so there was no mpirun involved. If you can suggest a test program I can use with mpirun to validate my openmpi environment and install, that would probably produce the output you would like to see. But

Re: [OMPI users] mca:base:select:( ess) No component selected!

Afraid I am confused. This was the entire output from the job?? If so, then that means mpirun itself wasn't able to find a launch environment it could use, so you never got to the point of actually launching an orted. Do you have ssh in your path? My best immediate guess is that you

Re: [OMPI users] mca:base:select:( ess) No component selected!

That was the output with plm_base_verbose set to 99 - it's the same output with 1. Yes, I'd like to use ssh. orted wasn't starting properly with orte_launch_agent (which was needed because my environment on the target machine wasn't set up), so that's why I thought I would try it directly on the

Re: [OMPI users] mca:base:select:( ess) No component selected!

Could you rerun that with -mca plm_base_verbose 1? What environment are you in - I assume rsh/ssh? I would like to see the cmd line being used to launch the orted. What this indicates is that we are not getting the cmd line correct. Could just be that some patch in the trunk didn't get

Re: [OMPI users] which gcc to compile openmpi with?

I compiled it with 2.95.3 and I tested the hello_c and ring_c example and they seemed fine. So I guess it worked with 2.95.3, am I right?? --- On Wed, 9/24/08, Jeff Squyres wrote: From: Jeff Squyres Subject: Re: [OMPI users] which gcc to compile openmpi

Re: [OMPI users] which gcc to compile openmpi with?

I don't think we've tested with 2.95 (that's ancient). I'm pretty sure we've tested with various versions of the 3 series. Unless you have a really good reason, you should probably prefer the newer compiler (IMHO). On Sep 24, 2008, at 11:46 AM, Brock Palen wrote: Those are really old
