Hi Jayesh,<BR> <BR>your modified version works for me but it's not what i wanted to do. I wanted to make the three processes (the client, the server and the spawned child) in the same intracommunicator, so the this intarcommunicator will have size 3, but with your version it contains only the spawned child and the server.<BR> <BR>Regards,<BR>Toufik<br> <BR><div><div id="SkyDrivePlaceholder"></div>> Date: Thu, 5 Apr 2012 11:32:18 -0500<br>> From: jayesh@mcs.anl.gov<br>> To: mpich-discuss@mcs.anl.gov<br>> CC: h_toufik7@hotmail.fr<br>> Subject: Re: [mpich-discuss] get several children of mpi_comm_spawn into one intracommunicator<br>> <br>> Hi,<br>> The slightly modified (don't disconnect an invalid comm) versions of your code works for me.<br>> Make sure that worker.exe and master.exe are in the same directory (Or else spawn() needs to be provided with the information).<br>> <br>> Regards,<br>> Jayesh<br>> <br>> ----- Original Message -----<br>> From: "toufik hadjazi" <h_toufik7@hotmail.fr><br>> To: mpich-discuss@mcs.anl.gov<br>> Sent: Thursday, April 5, 2012 3:32:11 AM<br>> Subject: Re: [mpich-discuss] get several children of mpi_comm_spawn into one intracommunicator<br>> <br>> <br>> <br>> Hi, <br>> <br>> <br>> <br>> <br>> I'm using windows 7 and i'm running the two applications using the commands: mpiexec -n 1 manager and mpiexec -n 1 worker. and for the code it is attached to this email <br>> <br>> thanks & regards, <br>> Toufik <br>> <br>> <br>> > Date: Wed, 4 Apr 2012 13:00:15 -0500 <br>> > From: jayesh@mcs.anl.gov <br>> > To: h_toufik7@hotmail.fr <br>> > CC: mpich-discuss@mcs.anl.gov <br>> > Subject: Re: [mpich-discuss] get several children of mpi_comm_spawn into one intracommunicator <br>> > <br>> > Hi, <br>> > How are you running your programs (Copy-paste the commands)?
