<div><div><span class="Apple-style-span" style="font-size: large;">Hi, I'm an amateur of Linux, and studying in Cluster with MPI recently. The version which I downloaded is the newest "mpich2-1.4", and OS is Red Hat Enterprise Linux 4 ES. I have two questions to be consulted, and appreciate for your attention. </span></div><div><span class="Apple-style-span" style="font-size: large;"><br></span></div><div><span class="Apple-style-span" style="font-size: large;">First, in the manual "Installer's Guide", 2.2-8, I should use command "which mpicc" and "which mpiexec" to check my installation. But according to informations I've found in internet, they all said there should be four command: "which mpd", "which mpicc", "which mpiexec" and "which mpirun" . And some guy tells me command "mpd" is replaced by other commands like "hydra" or etc. I don't know if I can't use "mpd" command, means that the MPICH program has not been installed successfully?
