We did have some kind of stdout/stderr truncation issue a little while ago, but I don't remember what version it specifically affected.
I would definitely update to at least Open MPI 1.10.4 (lots of bug fixes since 1.10.0). Better would be to update to Open MPI 2.0.1 -- that's the current generation and where all of our work is going these days. > On Oct 5, 2016, at 9:23 AM, Emre Brookes <e...@biochem.uthscsa.edu> wrote: > > $ cat /etc/redhat-release > CentOS Linux release 7.2.1511 (Core) > > $ yum list installed | grep openmpi > openmpi.x86_64 1.10.0-10.el7 @base > openmpi-devel.x86_64 1.10.0-10.el7 @base > > (1) When I run > $ mpirun -H myhosts -np myprocs executable > the job runs fine and outputs correctly to stdout > > (2) When I run > $ mpirun -H myhosts -np myprocs executable > stdout.log > The stdout.log file prematurely ends (without full output) > ... but the mpi executable itself seems to keep running forever until > manually terminated will a "kill". > > (3) When I run > $ mpirun -H myhosts -np myprocs executable | cat > stdout.log > the job runs fine and outputs correctly to the stdout.log file > > I tried playing with a 'stdbuf' prefix to the command, but this didn't seem > to help > I would like (2) to work, but have resorted to (3). > > I tried digging around in the parameters after seeing > https://github.com/open-mpi/ompi/issues/341 > and thinking it might be something similar, but didn't see any poll or epoll > in .conf > I am hesitant to try to compile from scratch and get away from the repo > release cycle. > > Is this a known bug? > If so, and if it has been fixed, would you recommend I install the latest > stable rpm of 1.10.4-1 from https://www.open-mpi.org/software/ompi/v1.10/ ? > > Thanks, > Emre > > > > > > > _______________________________________________ > users mailing list > users@lists.open-mpi.org > https://rfd.newmexicoconsortium.org/mailman/listinfo/users -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/ _______________________________________________ users mailing list users@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/users
