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

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
