When I execute this code with more than once process (-n > 1), this
error message appear. My code is a distributed compressor, that the
compress task is distributed. A single process reads a block from a
file, compress it and writes a compressed block to a file.

I already saw this post before, but this didn't help me. I'm not using
MPI_File_delete in my code.

Why do you need use this version ? the most part of moderns softwares
recommends the use of gcc version 3 or greater (the best is version
4).

[OMPI users] Newbie doubt.

[Davi Vercillo C. Garcia (デビッド)]

Hi,

I'm starting to use OpenMPI and I'm having some troubles. I wrote a
simple program that tries to open files using the function
MPI_File_open(). Like below:

#include 
#include 
#include 

#include 

int processoPrincipal(void);
int processosEscravos(void);

int main(int argc, char** argv) {
int meuRank, numeroProcessos;
MPI_File arquivoEntrada, arquivoSaida;

MPI_Init(, );
MPI_Comm_rank(MPI_COMM_WORLD, );
MPI_Comm_size(MPI_COMM_WORLD,);

MPI_File_open(MPI_COMM_WORLD, argv[1], MPI_MODE_RDONLY,
MPI_INFO_NULL, );
strcat(argv[1], ".bz2");
MPI_File_open(MPI_COMM_WORLD, argv[1], MPI_MODE_RDWR |
MPI_MODE_CREATE, MPI_INFO_NULL, );

if (meuRank != 0) {
processoPrincipal();
} else {
processosEscravos();
}

MPI_Finalize();
return 0;
}

But I'm getting a error message like:

*** An error occurred in MPI_Barrier
*** An error occurred in MPI_Barrier
*** after MPI was finalized
*** MPI_ERRORS_ARE_FATAL (goodbye)
*** after MPI was finalized
*** MPI_ERRORS_ARE_FATAL (goodbye)

What is this ?

[OMPI users] Problem with NFS + PVFS2 + OpenMPI

[Davi Vercillo C. Garcia]

Hi,

I'm trying to run my program in my environment and some problems are
happening. My environment is based on PVFS2 over NFS (PVFS is mounted
over NFS partition), OpenMPI and Ubuntu. My program uses MPI-IO and
BZ2 development libraries. When I tried to run, a message appears:

File locking failed in ADIOI_Set_lock. If the file system is NFS, you
need to use NFS version 3, ensure that the lockd daemon is running on
all the machines, and mount the directory with the 'noac' option (no
attribute caching).

exited on signal 15 (Terminated).

Why ?!

Which user are you using to execute make install ? Maybe you need some

[OMPI users] Introduce myself.

[Davi Vercillo C. Garcia]

HI all,

My name is Davi Vercillo and I'm from Brazil. I'm starting right now
to study MPI and I'll use the implementation of OpenMPI for this. I
want to know if there is a kind of "MPI for Dummies" that I can find
in Internet. Another thing that I would like to know is what the
diference with others implementations of MPI like MPICH, MPI-2, etc.

PS: Sorry about my english.
