Hi Jayesh, <BR> <BR>thanks for your answers, i solved the first problem but not the second one, i think my question wasn't clear enough: i have an application which uses MPI_Comm_spawn, when the call is done the parent and the spwaned child continue to run on the same console (cmd window) but i need to separate them (each one in a separate cmd window), i don't know if this is possible.<BR> <BR>Thanks & best Regards,<BR>Toufik.<br> <BR><div>> Date: Thu, 12 Apr 2012 09:58:59 -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] questions about MPI_Comm_spawn<br>> <br>> Hi,<br>> Argh, I missed your first question.
