The error I get became from the syntax I used to run my script. Fynally I've been able to run my R script uning mpirun. This is the string I used: $ mpirun -n 1 -hosts node02 R --slave -f /home/mpiuser/R_scripts/prova_clust.R I get a fatal errors using R with MPI in interactive mode: [mpiexec@master] match_arg (./utils/args/args.c:122): unrecognized argument pmi_args// [mpiexec@master] HYDU_parse_array (./utils/args/args.c:140): argument matching returned error// [mpiexec@master] parse_args (./ui/mpich/utils.c:1387): error parsing input array// [mpiexec@master] HYD_uii_mpx_get_parameters (./ui/mpich/utils.c:1438): unable to parse user arguments// Usage: ./mpiexec [global opts] [exec1 local opts] : [exec2 local opts] : ...// Please see the intructions provided at// http://wiki.mcs.anl.gov/mpich2/index.php/Using_the_Hydra_Process_Manager// for further details// After that R stops work.

It seems your MPICH installation is working fine. Are you sure the error is coming from MPICH? A quick google search suggests it may be a shell syntax error.

Hi my name is Riccardo, I have a linux cluster based on ubuntu with mpich2 installed. I try to run the examples:
mpiexec.hydra -f hosts -n 4 /home/mpiuser/bin/cpi
and all works. So I try to run a simple R script but I get an error:
Syntax error: word unexpected
How can I overcome this error?
