Re: [OMPI users] use accept/connect to merge a new intra-comm

I tried the 1.8 code base, and I'm afraid it doesn't work there either. After digging into the code, I can see why - I'm afraid that joining multiple singleton's isn't going to work until you get to the 1.9 series. I'll have to check to see if our current master can support it (I believe it

Re: [OMPI users] orted seg fault when using MPI_Comm_spawn on more than one host

I confess I am sorely puzzled. I replace the Info key with MPI_INFO_NULL, but still had to pass a bogus argument to master since you still have the Info_set code in there - otherwise, info_set segfaults due to a NULL argv[1]. Doing that (and replacing "hostname" with an MPI example code) makes

Yes, I did. I replaced the info argument of MPI_Comm_spawn with MPI_INFO_NULL. On Tue, Feb 3, 2015 at 5:54 PM, Ralph Castain wrote: > When running your comm_spawn code, did you remove the Info key code? You > wouldn't need to provide a hostfile or hosts any more, which is

Re: [OMPI users] orted seg fault when using MPI_Comm_spawn on more than one host

When running your comm_spawn code, did you remove the Info key code? You wouldn't need to provide a hostfile or hosts any more, which is why it should resolve that problem. I agree that providing either hostfile or host as an Info key will cause the program to segfault - I'm woking on that issue.

Re: [OMPI users] independent startup of orted and orterun

Appreciate your patience! I'm somewhat limited this week by being on travel to our HQ, so I don't have access to my usual test cluster. I'll be better situated to complete the implementation once I get home. For now, some quick thoughts: 1. stdout/stderr: yes, I just need to "register"

Hi Ralph, Besides the items in the other mail, I have three more items that would need resolving at some point. 1. STDOUT/STDERR currently go to the orte-dvm console. I'm sure this is not a fundamental limitation. Even if getting the information to the orte-submit instance would be

Re: [OMPI users] orted seg fault when using MPI_Comm_spawn on more than one host

Setting these environment variables did indeed change the way mpirun maps things, and I didn't have to specify a hostfile. However, setting these for my MPI_Comm_spawn code still resulted in the same segmentation fault. Evan On Tue, Feb 3, 2015 at 10:09 AM, Ralph Castain

Re: [OMPI users] configuring a code with MPI/OPENMPI

Yes, you still need to tell the configure script about all your MPI env variables (I guess you haven't or have not set them all). MPICC=mpiicc MPIFC=mpifort or the equivalent. Probably some more are needed. Please ask on the abinit forum about how to set the MPI executables correctly. But the

Re: [OMPI users] configuring a code with MPI/OPENMPI

Without knowing anything about the application that you are trying to build, it's really hard to say. You should probably be asking the support mailing lists for that specific application -- they would better be able to support you. This list is for Open MPI, which is likely one of the MPI

Re: [OMPI users] orted seg fault when using MPI_Comm_spawn on more than one host

If you add the following to your environment, you should run on multiple nodes: OMPI_MCA_rmaps_base_mapping_policy=node OMPI_MCA_orte_default_hostfile= The first tells OMPI to map-by node. The second passes in your default hostfile so you don't need to specify it as an Info key. HTH Ralph On

Re: [OMPI users] orted seg fault when using MPI_Comm_spawn on more than one host

Hi Ralph, Good to know you've reproduced it. I was experiencing this using both the hostfile and host key. A simple comm_spawn was working for me as well, but it was only launching locally, and I'm pretty sure each node only has 4 slots given past behavior (the mpirun -np 8 example I gave in my

Re: [OMPI users] configuring a code with MPI/OPENMPI

First try and correct your compilation by using the intel c-compiler AND the fortran compiler. You should not mix compilers. CC=icc FC=ifort Else the config.log is going to be necessary to debug it further. PS: You could also try and convince your cluster administrator to provide a more recent

I'm afraid I don't quite understand what you are saying, so let's see if I can clarify. You have two fortran MPI programs. You start one using "mpiexec". You then start the other one as a singleton - i.e., you just run "myapp" without using mpiexec. The two apps are attempting to execute an
