Hi Marce, there is a new mailing list for R and HPC: [EMAIL PROTECTED] This is probably a better list for your question.
Probably Rmpi does not find the correct Rmpi implementation. Have you installed a second mpi implementation (lammpi)? How do you have installed Rmpi? Did you compiled it to the mpi libraries? R CMD INSTALL --configure-args="--with-mpi=MPIPATH" Rmpi Best Markus Marce wrote: > Hi all, > now I'm testing R in a "virtual cluster", made it with VirtualBox.
