I've used this for years, just updated open-mpi to 3.0.0 and reloaded R, have reinstalled doMPI and thus Rmpi but when I try to use startMPICluster, asking for 6 slots (there are 12 on this machine) I get this error. Where can I start to debug it?
Thanks J -------------------------------------------------------------------------- There are not enough slots available in the system to satisfy the 6 slots that were requested by the application: /usr/lib/R/bin/Rscript Either request fewer slots for your application, or make more slots available for use. -------------------------------------------------------------------------- Error in mpi.comm.spawn(slave = rscript, slavearg = args, nslaves = count, : MPI_ERR_SPAWN: could not spawn processes -- Jim Maas jimmaasuk at gmail.com
