[mpich-discuss] How codes are distributed?

[Jierui XIE]

I largely followed the instruction at
https://help.ubuntu.com/community/MpichCluster
which is for a older version MPICH2-1.0.5.

I did NOT use the "make" to install, instead, I just used the apt-get
command in Ubuntu as:
	sudo apt-get install mpich2
I think it used the default the location and I can see
    dpkg -L mpich2

         /usr/share/mpich2
		/usr/share/mpich2/mpd.py
		/usr/share/mpich2/mpdallexit.py
		/usr/share/mpich2/mpiexec.py
		....
		/usr/bin
		/usr/bin/mpdroot
		/usr/bin/pmi_proxy
		/usr/bin/mpiexec.gforker
		/usr/bin/mpiexec.hydra
		/usr/share/doc/mpich2/changelog.gz
		/usr/share/doc/mpich2/README.gz
		/usr/share/man/man1/mpirun.mpich2.1.gz
		/usr/share/mpich2/mpdrun.py
		/usr/share/mpich2/mpirun.py
		/usr/bin/mpd
		/usr/bin/mpdallexit
		/usr/bin/mpdboot
		/usr/bin/mpdcheck
		/usr/bin/mpdcleanup
		/usr/bin/mpdexit
		/usr/bin/mpdgdbdrv
		/usr/bin/mpiexec.mpich2
		/usr/bin/mpirun.mpich2
	...


I installed mpich2 on ALL machines.
SHOULD I do that or just install it on one machine and share the
folder with others using NFS??

Maybe I should re-install mpich2 using make?

Thanks.
