It is possible to run CLaMS on multi-processor machines using MPI.

Intel Compiler 17.0.1

The MPICH Library 3.2 is installed in directory /usr/nfs/local/local/mpich-3.2-ifort-17.0.1.

Add the bin subdirectory of the installation directory of MPICH library to your path:
```
PATH=/usr/nfs/local/local/mpich-3.2-ifort-17.0.1/bin:$PATH
export PATH
```
Remove serial compiled object files:
```
make distclean
```
Compile with MPI:
```
make useMPI=true progname
```
Execute on <n> CPUs:
```
mpiexec|mpirun -np <n> <progname>
```

Intel Compiler 14.0.3

The MPICH Library is installed in directory /usr/nfs/local/local/mpich-intel. Add the bin subdirectory of the installation directory of MPICH library to your path:
```
PATH=/usr/nfs/local/local/mpich-intel/bin:$PATH
export PATH
```
Remove serial compiled object files:
```
make distclean
```
Compile with MPI:
```
make useMPI=true [useComp=ifc] progname
```
Execute on <n> CPUs:
```
mpiexec|mpirun -np <n> <progname>
```

Portland Compiler 14.6

It is necessary to make the path of the MPI libraries (included in the portland compiler suite) public by executing:
```
. /opt/pgi/linux86-64/14.6/mpi.sh
```
Remove serial compiled object files:
```
make distclean
```
Compile with MPI:
```
make useMPI=true [useComp=pgi] progname
```
Execute on <n> CPUs:
```
mpiexec|mpirun -np <n> <progname>
```

-In the following a short How to:

First it is necessary to make the path of the MPI libraries public by executing:

for 64bit machines:

{{{
. /opt/pgi/linux86-64/10.4/mpi.sh
+ The MPICH Library 3.2 is installed in directory ''/usr/nfs/local/local/mpich-3.2-ifort-17.0.1''.

-for 32bit machines:

{{{

+ Remove serial compiled object files:

-Then compile the needed programs by executing:

{{{
make useMPI=true
+ Compile with MPI: 
 {{{
make useMPI=true progname
-Line 32:
+Line 31:
-Before running the CLaMS script or a single program you have to execute:

{{{
ssh-add
}}}

This is necessary, because the processes communicate per ssh.

The programs must be called as following:

{{{
mpirun -np # program

# - number of processors
+ Execute on <n> CPUs:

mpiexec|mpirun -np <n> <progname>
