[OMPI devel] mpiexec without -hosts option

[Victor Rodriguez]

HI team
( if this is not the proper channel please point me )

I am trying to implement MPI on yocto ( first try ) :

http://cgit.openembedded.org/meta-openembedded/commit/meta-oe/recipes-devtools/mpich/mpich_3.1.1.bb?id=824b6de96ddfe791a0013d96a84ad49de8e04d38

I tested running the mpibench
http://icl.cs.utk.edu/projects/llcbench/mpbench.html

On a minnow board MAX and work just amazing :)

The problem is that I did the test with just one board, when I tried
to implement it for more than one platform I decided to use the -hosts
option ( or the -H hostfile ) but the only option that I have :

root@qemux86:~# mpiexec --version
invalid mpiexec argument --version
Usage: mpiexec -usize  -maxtime  -exitinfo -l\
   -n  -soft  -host  \
   -wdir  -path  \
   -file  -configfile  \
   -genvnone -genvlist  -genv name value\
   -envnone -envlist  -env name value\
   execname \
   [ : -n  ... execname ]

I should have realize something was wrong because there was no mpirun
I just have :

root@qemux86:~# mpi
mpic++mpichversion  mpiexec
mpicc mpicxxmpivars

My configuration is something like :

"--disable-fortran \
 --disable-rpath \
 --with-pm=gforker"

The first one is just because I dont want fortran and the last 2
because of QA problems with Yocto

I wonder if any part of my configurations is wrong or what part I am
doing wrong :( . Cause I really need to run on multiple systems :(

Best regards

[OMPI devel] channel initialization failed MPI

[Victor Rodriguez]

Hi

I am facing the following issue on my MPI build from source code:

(the only change in config was disable fortran )

Any help is more than welcome


root@intel-corei7-64:~/test# mpirun -n 2 ./mpi_hello

Hi team

I am porting open mpi to Yocto but at moment of ./configure I have this problem

If you meant to cross compile, use `--host'.

DO you know if there is any flag that I should enable to disable check
cross compiling

Also Yocto do not support fortran , how can I disable fortran ?


Thanks a lot and regards
