[OMPI users] Yet another stdin problem

Dear all, I'm trying to lunch an MPI program using the command mpirun -np 64 my_exe < inputs.txt inputs.txt actually contains the entries that are read by all processes however it seems that openmpi redirect the stdin only to the processes with rank 0. with leads to a segmentation fault on

Re: [OMPI users] Yet another stdin problem

Why not modify your program to read inputs.txt instead of stdin? 2009/10/7 Kilou Zelabia : > Dear all, > > I'm trying to lunch an MPI program using the command > > mpirun -np 64 my_exe < inputs.txt > > inputs.txt actually contains the entries that  are read by all

Ok thanks! That's a solution but i was wondering if there could exist a more elegant one ? means without any modification at the source level De : Roman Cheplyaka À : Open MPI Users Envoyé le : Mer 7 Octobre

Re: [OMPI users] Re : Yet another stdin problem

As a slight modification, you can write a wrapper script #!/bin/sh my_exe < inputs.txt and pass it to mpirun. 2009/10/7 Kilou Zelabia : > Ok thanks! > That's a solution but i was wondering if there could exist a more elegant > one ? means without any modification at the

Re: [OMPI users] Re : Yet another stdin problem

Or better still if you want to be able to pass the filename and args on the mpirun command line use the following and then run it as mpirun -np 64 ./input_wrapper inputs.txt my_exe #!/bin/bash FILE=$1 shift "$@" < $FILE In general though using stdin on parallel applications is rarely a good

Re: [OMPI users] Re : Yet another stdin problem

FWIW: an upcoming version will have the ability for you to specify all ranks to receive stdin...but that's a little ways off. For now, only rank=0 does. On Oct 7, 2009, at 9:42 AM, Roman Cheplyaka wrote: As a slight modification, you can write a wrapper script #!/bin/sh my_exe < inputs.txt

Re: [OMPI users] Making RPM from source that respects --prefix

Hello Jeff and Kiril, Thank you for your responses. Based on the information you both provided, I was able to get buildrpm to make the OMPI RPM the way I wanted. I ended up having to define _prefix , _mandir , and _infodir . Additionally, I found I had to use --define "shell_scripts_basename
