I'm new to MPI, and could really use some advice regarding shared-memory
message passing on a 2 processor Sun Sparc10 running Solaris 2.4

I've had no problems using sockets to communicate between processes on the
workstation, but can't "coerce" it to use shared memory.  My errors are as
follows:

-----------
bm_slave_1_19358: (0.122692) process not in process table; my_unix_id = 19358
my_host=opus
bm_slave_1_19358: (0.127803) Probable cause:  local slave on uniprocessor
without shared memory
bm_slave_1_19358: (0.128440) Probable fix:  ensure only one process on opus
bm_slave_1_19358: (0.128845) (on master process this means 'local 0' in the
procgroup file)
bm_slave_1_19358: (0.129204) You can also remake p4 with SYSV_IPC set in the
OPTIONS file
------------

I have remade the configuration by setting SYSV_IPC as specified in the error
output.  I've also remade the configuration using both the ch_p4 device
specification, and the ch_mem device specification as well, all to no avail.  

Any input would be greatly appreciated.  Thanks!
