Mark - I've followed the instructions on the wiki. The last step says to email the mailing list, as I have done. I'm not sure about your comment for not needing a complete make if we're looking for MPI. There are situations where the program will be used in single-processor mode, as well as MPI. I'm not too concerned with the time it takes to compile all of this (it's only about 8 minutes for the whole lot).

Sure. The point is to avoid compiling and installing MPI versions that aren't useful, while not installing the non-MPI versions that are... Admittedly, the loss case for a full install of both flavours is pretty small.

Jussi - I'm trying to compile the packages myself since the pre-made RPM's don't seem to install the libraries needed. Furthermore, the LAM RPM would constantly complain about not being able to find gcc-g77 - a package found in CentOS4 but not CentOS5 (it's now referred to as compat-gcc-34-g77 - the names don't agree so rpm complains).

So that's why you can force RPM to do things when you do happen to know better that it does.

Also, installing LAM from yum fails to put the required binaries where they belong! There's no lamboot, mpmirun, lamhalt, etc to be found anywhere in the path.

Define "belong". :-) You can find out from yum and RPM what files were installed with each package... that will allow you to find the correct things to add to your path.

I've found that it's often much less of a headache if you can find the source and start from scratch (this is the FreeBSD child in me talking). My main problem so far is that the library for GSL is installed in the wrong location and that mdrun_mpi doesn't seem to have been compiled. If the source is provided, it should be possible to compile it into a functional program...

Sure. I told you last time
a) that GSL is only useful for a tiny piece of functionality and
b) how to see what mdrun got installed where.
