Hi I am trying to utilize my dual core processor (and later a High-performance clusters (HPC) ) by using the Rmpi, snow, snowfall, ... packages, but I am struggling at the beginning, i.e. to initialise the "cluster" on my dual core computer. Whenever I try to initialize it (via sfInit(parallel=TRUE, cpus=2) or mpi.spawn.Rslaves(nslaves=2) ), I get an error message:
> sfInit(parallel=TRUE, cpus=2) Forced parallel. Using session: XXXXXXXXR_rkrug_143706_092708 Error in mpi.comm.spawn(slave = mpitask, slavearg = args, nslaves = count, : MPI_Comm_spawn is not supported. Error in sfInit(parallel = TRUE, cpus = 2) : Starting of snow cluster failed! Error in mpi.comm.spawn(slave = mpitask, slavearg = args, nslaves = count, : MPI_Comm_spawn is not supported. > and > mpi.spawn.Rslaves(nslaves=2) Error in mpi.spawn.Rslaves(nslaves = 2) : You cannot use MPI_Comm_spawn API > I followed the pdf "Developing parallel programs using snowfall" by Jochen Knaus,. installed the relevant libraries and programs, but it does not work. I am stuck. Any help appreciated, Rainer -- Rainer M. Krug, PhD (Conservation Ecology, SUN), MSc (Conservation Biology, UCT), Dipl. Phys.
