2. RSH
3. NIS (ypserv)
Needed Daemon

5. rstatd (for RPC)
6. portmap
7. rsh
8. xinetd
9. ypserv (server)
10. yppasswdd (server)
11. ypbind (client) <-- chkconfig ypbind on Installation tar zxvf mpich2.tar.gz ######### HOSTS ################## All /etc/hosts file in all client should contain all nodes information or it will fail. ######### mpich ################## use another user login and use these tools. Get into mpich directory ./configure --prefix=/home/hpcuser/mpich2 <-- not the same with the source folder make;make all;make install add "export PATH=/home/hpcuser/mpich2/bin/:$PATH" to ~/.bash_profile ######### mpd ################## cd $HOME touch .mpd.conf chmod 600 .mpd.conf add "secretword=111111" into this file #mpd& --> start the mpd daemon for mpiexec command.
You can test by "mpiexec -n 1 /bin/hostname" to see if you can run mpi2.
Or use "mpdallexit" to exit the mpd daemon.
######### RSH ##################
It used on client OS.
Open rsh daemon with xinetd service
modify PAM rule under /etc/pam.d/rsh
**remove the "pam_rhosts_auth" option
DON'T USE RSH AS ROOT!!!!!! (Permission Deny)
