|
|---|
| 10 | ============
|
|---|
| 11 |
|
|---|
| 12 | 1. Check "G4MPI.gmk" for yor MPI configuration:
|
|---|
| 13 |
|
|---|
| 14 | * Set "G4MPIROOT", which is the root path to your MPI library.
|
|---|
| 15 | * Redifine CXX as (wrapped) MPI C++ compiler.
|
|---|
| 16 | * Specify additional include paths and compiler flags to "CPPFLAGS".
|
|---|
| 17 |
|
|---|
| 18 | Sample makefiles for (LAM, MPICH2, OpenMPI) are also presented.
|
|---|
| 19 | An example of "G4MPI.gmk":
|
|---|
| 20 |
|
|---|
| 21 | # ===========================================================
|
|---|
| 22 | # Makefile for building G4MPI (LAM)
|
|---|
| 23 | # ===========================================================
|
|---|
| 24 |
|
|---|
| 25 | ifndef G4MPIROOT
|
|---|
| 26 | G4MPIROOT = /opt/lam
|
|---|
| 27 | endif
|
|---|
| 28 |
|
|---|
| 29 | # additional flags
|
|---|
| 30 | CXX := mpic++
|
|---|
| 31 | CPPFLAGS += -I$(G4MPIROOT)/include
|
|---|
| 32 |
|
|---|
| 33 |
|
|---|
| 34 | 2. Build the library
|
|---|
| 35 |
|
|---|
| 36 | # make
|
|---|
| 37 | # make includes
|
|---|
| 38 |
|
|---|
| 39 | The library (libG4UImpi) will be created in $G4LIB,
|
|---|
| 40 | and header files will be installed into $G4INCLUDE.
