[Rainer M Krug]

Hi

I managed tio install Rmpi and to load it, but I get the following
errormessage when I try to create an MPI cluster and R hangs (no
response):

library(Rmpi)
[head001:15781] mca: base: component_find: unable to open osc pt2pt:
file not found (ignored)
> library(snow)
> cl <- makeCluster(2, type = "MPI")
Rscript execution error: No such file or directory
Rscript execution error: No such file or directory

I am using the following version:

arch           x86_64

system         x86_64, linux-gnu
