hi all,
running Mpich on an i686 PC cluster w/RedHat, interested in finding out
about a couple things in the Machine.g77_mpich file:
1) for setting the MACHINEFLAGS, the default settings are:
setenv MACHINEFLAGS "-DISTAR2 -DREGNML -DMPI"
after reading the 0README.parallel file, it is suggested that the flags
-DMPI_NATIVE and -I/path_to_mpich_mpif.h also be added.
the question i have is this: in addition to these flags, what sort of
success have others had in using other flags (e.g. Ewald specific flags
such as -DEWALD, etc. ?). optimization under gcc? expanding functionality
of AMBER... ?
2) still curious about the line:
setenv MPICH_LIB mpich
does the value "mpich" need to be customized for my system? what should it
be? the previous line,
setenv MPICH_LIBDIR $MPICH_HOME/lib
declares the mpich library, so it is not clear what this MPICH_LIB
variable is actually referring to.
gratefully yours,
charles
