LAM: configure LAM

Dear all:

I have problems with installing LAM.

First of all, let me know how to remove LAM/MPI.  I tried to
install  
many times in different ways (different path), so many files
were  
scattered over the system.  I want to make clean install. 
Usually, I  
used the default path /usr/local.  But, there are already
other files  
irrelevant with LAM/MPI.

The second question is concerning with strategy of system
configuration.
With the default path, I succeeded to install and it works
well as  
far as I access it within the local node. Next issue is to
extend  
this system over all the other nodes, which are connected by
NFS. Of  
course, I understand importance of bypassing mechanism for
passwords;  
I use RSA authentication. Our system is configured such a
way that  
only user directories are mounted by NFS. The default path
/usr/local  
is not mounted in NFS. Hence, I think this is reason, it
does not  
make response.
So, my question is whether I should install LAM/MPI in the
user  
directory which can be access from all the users. If this is
not the  
case, should I configure the system from beginning in a way
that the  
directory /usr/local is mounted by NFS?

Thanks advance,

Hi, Joe:

But, OpenMPI is too new, and I am disappointed to know that
even  
manual is lack at present time. For beginners it is too hard
without  
manuals.

I used lam-7.1.4.tar.gz.

Yeah, I can manage the path.
My concern is wether the other users can access even if the
installed  
directory is set to be in my home directory.

My current system was already dirty, because of many
attempts of  
installation, and hence it was difficult to see whether my 

installation was wrong or other problems.

Fair enough, but did you look at LAM's extensive
installation manual?   
There are detailed instructions in there about how to
install and  
uninstall LAM.  The FAQ also describes several common
installation  
scenarios.

Do you have questions that are not answered by the install /
user  
guides and/or the FAQ?

Be aware that LAM is not under active development any more;
all  
further effort is going into Open MPI.  The FAQ and man
pages are  
currently the best resource for using Open MPI; using Open
MPI is  
actually quite similar to LAM because at least some of the
core Open  
MPI team came from LAM.  The big difference is that there is
no  
lamboot/lamhalt command in Open MPI.
