Greetings,
I'm doing software fault injection in a parallel application to evaluate
the effect of hardware failures to the execution. My question is how to
execute the faulty version of the application on one node and the
fault-free version on all other nodes in the same run?
I understand th
Fixed on the trunk; queued up for the release branches.
Thanks!

Hi,
I am trying to install openmpi 1.4.1 on my cluster with linux ( RH EL 3 upd
3 ).
I want to run Ls dyna job on cluster, but it showed error as some files are
missing.
I also tried to copy shared lib files from ls dyna but then open mpi stops
working.
I am attaching ompi-output files.
Kindly help
The "WHEN COMMUNICATOR IS AN INTER-COMMUNICATOR" section in the man page
for MPI_Allreduce (in both 1.4.1 and the current SVN trunk) mentions the
use of a root process and a "root" parameter name (which doesn't exist for
MPI_Allreduce). Should I add this to Trac?

Have a look at MPI_Type_create_struct().

The code you showed was incorrect -- you were waiting on an uninitialized
variable. Perhaps that code was only a snipit...?

The data that I want to send via MPI is in the form of a struct:
struct myDataStruct {
struct subData1 {
int position[2];
int length[2];
};
struct subData2 {
float *data1;
float *data2;
float *data3;
float *data4;
};
struct subData3 {
float

How does that work, exactly? I thought the OMPI SGE integration didn't
support core binding, but good if it does.
Actually, that wasn't the problem. My code is working now with no changes to
it. Not sure what the problem was but it wasn't the called to MPI_Send
blocking.

'zactly correct.
You currently have an MPI_Wait on the sender side for no reason -- the request
is only filled in on the receiver. So you're waiting on an uninitialized
variable on the sender.
MPI_Send is a "blocking" send. MPI
No problem - I got to learn something too!

Hi Mahesh
At least in simple cases you can use normal socket functions for this.
I used this in order to change the run-time behaviour of an application
of a master-worker MPI application. I implemented a simple TCP-Server
which runs in a separate thread on the Master processor; connecting to

Hello,
Could you pl tell me how to connect a client(not in any mpi group ) to a
process in a mpi group.
(i.e. just like we do in socket programming by using connect( ) call).
Does mpi provide any call for accepting connections from outside
processes?
