Subject: [OMPI users] mpirun - All Nodes Filled

Simple question for today ! I am working on converting a public domain code suite ( to use openmpi rather than mpiJava. So far, all has gone well, other than the usual issues with getting all the paths and variables straightened out. For automation purposes, I would like to be able to specify everything from the command line, rather than using files. Why does this command work: chuck-> /usr/local/bin/mpirun -np 1 /usr/bin/java -version java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-10M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode) But this one does not: chuck-> /usr/local/bin/mpirun -np 1  -host localhost /usr/bin/java -version -------------------------------------------------------------------------- All nodes which are allocated for this job are already filled. -------------------------------------------------------------------------- Nor does this one: chuck-> cat hostfile localhost slots=2 chuck->/usr/local/bin/mpirun -np 1 -hostfile hostfile /usr/bin/java -cp . -version -------------------------------------------------------------------------- All nodes which are allocated for this job are already filled. -------------------------------------------------------------------------- For reference: chuck-> /usr/local/bin/mpirun -version mpirun (Open MPI) 1.7rc5 Report bugs to chuck-> uname -a Darwin iMac.local 10.8.0 Darwin Kernel Version 10.8.0: Tue Jun  7 16:32:41 PDT 2011; root:xnu-1504.15.3~1/RELEASE_X86_64 x86_64 My build was done with "configure --enable-mpi-java --prefix=/usr/local". Thanks for any insight ! Chuck Mosher chuckmosher_at_[hidden]
