Re: [OMPI users] Yet another stdin problem

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 source level > > ____ > De : Roman Cheplyaka > À : Open MPI Users > Envoyé le : Mer 7 Octobre 2009, 17 h 06 min 55 s > Objet : 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 processes >> however it seems that openmpi redirect the stdin only to the processes >> with >> rank 0. with leads to a segmentation fault on the other processes. >> The option "-stdin rank" doesn't help since i need all processes read the >> inputs.txt file. >> >> I'v tested with openmpi 1.3 and 1.2 whitout success. >> >> Thanks in advance for you help. >> >> Zellabia.

[OMPI users] VampirTrace: time not increasing
I got the following problem while trying to run vt-enabled HPL benchmark on a single 8-core Linux node. OTF ERROR in function OTF_WBuffer_setTimeAndProcess, file: OTF_WBuffer.c, line: 308: time not increasing. (t= 2995392288, p= 2) vtunify: Error: Could not read events of OTF stream [namestub ./a__ufy.tmp id 1] vtunify: An error occurred during unifying events - Terminating ... Sometimes instead of above message I get this: vtunify: vt_unify_events_hdlr.cc:37: int Handle_Enter(OTF_WStream*, uint64_t, uint32_t, uint32_t, uint32_t): Assertion `global_statetoken != 0' failed. A program is automatically instrumented (all I did was changing mpicc to mpicc-vt), compiled and run with latest svn of Open MPI, command: mpirun -np 8 --mca btl self,sm hpl The same problem was with the latest release version. When I run it with less number of processes, it works fine. Any ideas? -- Roman I. Cheplyaka
