Hi, <BR> <BR>I am using mpich2-1.4.1p1 on a windows 7 32 bits. I want to spawn processes on other machines, which has the same version of mpich and windows 7, but it fails giving me the output "Aborting: unable to connect to otherHost", where otherHost represent the ohter machine. I don't know why it fails 'cause when I tried to ping the two machines it worked well and the firewalls are deactived on both machines.<BR>Does someone know what it could be the problem?<BR>PS : I used the command : mpiexec -hosts 1 myHost otherHost myApp.exe and I used the info key "host" to select the host of MPI_Comm_spawn.<BR> <BR>best regards, <BR>Toufik.<BR> </div></body>
