Hi George I just tried that and got a different error message:
------------------------------------------------------------------------ -- No available pml components were found! This means that there are no components of this type installed on your system or all the components reported that they could not be used. This is a fatal error; your MPI process is likely to abort. Check the output of the "ompi_info" command and ensure that components of this type are available on your system. You may also wish to check the value of the "component_path" MCA parameter and ensure that it has at least one directory that contains valid MCA components. ------------------------------------------------------------------------ -- [node258:13595] PML ^cm cannot be selected ------------------------------------------------------------------------ -- These are the lines in my GridEngine script: setenv OMPI_MCA_btl "openib,self,sm" setenv OMPI_MCA_pml "^cm" mpirun -np $NSLOTS $exe The run appears to fail. Am I doing something wrong here?
