|
dnl This macro tries to find out how to compile programs that
|
||
|
|
dnl use MPI (Message Passing Interface), a standard API for
|
||
|
|
dnl parallel process communication (see http://www-unix.mcs.anl.gov/mpi/)
|
||
|
|
dnl
|
||
|
|
dnl On success, it sets the MPICC, MPICXX, or MPIF77 output variable to
|
||
|
|
dnl the name of the MPI compiler, depending upon the current language.
|
||
|
|
dnl (This may just be $CC/$CXX/$F77, but is more often something like
|
||
|
|
dnl mpicc/mpiCC/mpif77.) It also sets MPILIBS to any libraries that are
|
||
|
|
dnl needed for linking MPI (e.g. -lmpi, if a special MPICC/MPICXX/MPIF77
|
||
|
|
dnl was not found).
|
||
|
|
dnl
|
||
|
|
dnl If you want to compile everything with MPI, you should set:
|
||
|
|
dnl
|
||
|
|
dnl CC="$MPICC" #OR# CXX="$MPICXX" #OR# F77="$MPIF77"
|
||
|
|
dnl LIBS="$MPILIBS $LIBS"
|
||
|
|
dnl
|
||
|
|
dnl NOTE: The above assumes that you will use $CC (or whatever)
|
||
|
|
dnl for linking as well as for compiling. (This is the
|
||
|
|
dnl default for automake and most Makefiles.)
|
||
|
|
dnl
|
||
|
|
dnl The user can force a particular library/compiler by setting the
|
||
|
|
dnl MPICC/MPICXX/MPIF77 and/or MPILIBS environment variables.
|
||
|
|
dnl
|
||
|
|
dnl ACTION-IF-FOUND is a list of shell commands to run if an MPI
|
||
|
|
dnl library is found, and ACTION-IF-NOT-FOUND is a list of commands
|
||
|
|
dnl to run it if it is not found. If ACTION-IF-FOUND is not specified,
|
||
|
|
dnl the default action will define HAVE_MPI.
