Hi every body at LAM/MPI
Introduction:
I have recently subscribed to this mailing list. I am glad to that I have
entered the community of parallel programming.
I am newbie at LAM/MPI (and not expert at LINUX) at this point; and have a
problem with LAM/MPI 7.0.6
My case:
I have made my small cluster with 6 nodes (64bit) and installed CentOS
4.4(64bit) on each of them. During Linux installation, I choose LAM to
be
installed for head node as well as each of compute nodes. I have done
lamboot successfully.
My questions:
1- By default, wrapper compiler mpif77 refers to g77 compiler. But, I want
to use gfortran instead of g77 in parallel mode, .i.e. I want that mpif77
uses gfortran while compiling a FORTRAN program. Please help me.
(I have read LAM installation guide and had a look at user guide. All over
these mans authors pre-suppose that you want to install LAM yourself.
However, in my case, CentOS ITSELF has installed LAM and I don't know where
are source files, installation directory, etc.)
2- To compile and run parallel programs is it necessary to install LAM/MPI
as well as C/F compilers in head node and ALL compute nodes? (NFS running on
head with /home directory)
Best wishes,
