[mpich-discuss] questions about MPI_Comm_spawn

[toufik hadjazi]

Hi Jayesh,  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. Thanks & best Regards,Toufik.
