4.1 and MPI

[Eitan]

Hi All,

I am starting to migrate a model I have to run parallel using MPI.

First what I can contrib:
1. I had to put the MPI bin dir in the path before invoking configure
2. I had to manually edit the MPI_LIBS (used the hint about quoting
the mpicxx -showme)
3. Still I had to add manually the resulting MPI_LIBS to ALL_ENV_LIBS
and KERNEL_LIBS in Makefile.inc to get src/env and examples to compile
(the reason is that using shared libs they are not added to the LIB).

Now questions:
1. Is there a migration path to Parallel Sim with MPI?
2. Anything on top of not using bi-directional links and making sure
cross module function calls are located in same "partition" ?

Many thanks

Eitan

Setting up Cmdenv...

RUNTIME ERROR. A cRuntimeError exception is about to be thrown, and you
requested (by setting debug-on-errors=true in the ini file) that errors
abort execution and break into the debugger.

You should now probably be running the simulation under gdb or another
debugger. The simulation kernel will now raise a SIGABRT signal which will
get you into the debugger. If you are not running under a debugger, you can
still use the core dump for post-mortem debugging. Once in the debugger,
view the call stack (in gdb: "bt" command) to see the context of the
runtime error.

<!> Error: cFileCommunications: missing -p<procId>,<numPartitions> switch on the command line.

TRAPPING on the exception above, due to a debug-on-errors=true configuration option. Is your debugger ready?
