problem with MPI compilation

Palabos General
#1

Hi Everybody,

I try with the Palabos to compile a routine that I have in parallel mode. For that, I first installed mpich and next, I used “make” which apparently compiled the code with success.

However when I type : >> mpirun -np 2 ./geo 300 10 0.4 0.0001

I get the error:

mpiexec_app72: cannot connect to local mpd (/tmp/mpd2.console_vince); possible causes:

  1. no mpd is running on this host
  2. an mpd is running but was started without a “console” (-n option)
    In case 1, you can start an mpd on this host with:
    mpd &
    and you will be able to run jobs just on this host.
    For more details on starting mpds on a set of hosts, see
    the MPICH2 Installation Guide.

Could you hint what I am missing.

Regards,

Did you tried the suggestions?

hi,
I am trying to compile the cylinder2d example on a Mac OS X version 10.6.8
(palabos-v1.2r0)

I get the following error message below and would be grateful for suggestions

Hi,

I have installed OpenMPI, but bug is as follows:

make

What’s wrong? and I do want

Set MPI-parallel mode on/off (parallelism in cluster-like environment)

MPIparallel = true

How should I do with it?

Help!

thanks!

Ah, something went wrong with your OpenMPI installation. Under Ubuntu, I think that additionally to the package “openmpi”, you should install the package “openmpi-dev”.
