I am new to this list and I would like to know how to configure
the MPICH software to work in a cluster of computers using Linux-Mandrake
I would like to use the Absoft fortran compilers and GNU's gcc and
g++ that come with Linux. How should I configure MPICH? Is the following
--with-arch=LINUX -cc=gcc -cflags="-O2" -c++=g++
-fflags="-N109" -f90=/usr/absoft/bin/f90 -f90flags= -fortnames=CAPS
--without-devdebug -mpe -file_system=nfs+ufs
-prefix=/usr/local/mpich-1.2.1-pgi directory to install software,
--with-device=ch_p4 appropiate device for Linux clusters.
--with-arch=LINUX OS used.
-cc=gcc GNU's C compiler.
-cflags="O2" Options for the C compiler. What does the "O2" option do?
-c++=g++ GNU's C++ compiler.
-c++flags="O2" Options for the C++ compiles. What does the "O2" option
-fc=/usr/absoft/bin/f77 Full path to Absoft's f77 compiler.
-fflags="-N109" For folding all symbolic names to upper case. What for?
-f90=/usr/absoft/bin/f90 Full path to Absoft's 790 compiler.
-f90flags= Options for f90 compilers. Is it correct
to have it empty?
-fortnames=CAPS What is this for? I didn't find this in
the manual for installation.
--without-devdebug Since I am not a MPI implementor.
-mpe Extensions for logging and X graphics.
-file_system=nfs+ufs What's ufs?
Thanks in advance for reding this e-mail.
