Make sure your PATH contains the path to the mpich binaries. Otherwise you will get errors like /usr/bin/ld: cannot find -lmpich.
#Install mpi on node install
This will install the libraries in /home/you/mpich-install/lib. configure -prefix=/home/you/mpich-install In the following steps it is assumed that the home directory is shared. You need a shared directory for all nodes. Under ubuntu feisty: sudo apt-get install build-essential. It describes, what you need to compile mpich. There's a how-to for installing Mpich2 in Ubuntu/Debian in Ubuntu Wiki : Install from sourceĭownload the mpich2-1.0.6.tar.gz or any newer version from and unpack it. Under ubuntu/debian you can install the following packages: libmpich-mpd1.0-dev mpich-mpd-bin On your development machines, where you compile your application, you must install the development libraries and FPC too. Your cluster can contain for example Windows and Linux machines, with different number of CPUs and memory. A cluster can be any set of computers / virtual machines. There you must give a valid windows user name and password.Ĭ:\Program Files\MPICH2\bin\mpiexec.exe -n 10 C:\Program Files\MPICH2\examples\cpi.exeįirst you need to install the MPICH2 library on all computers of your cluster. The best way is to put all nodes into a domain and use SSPI.įor simple testing mpi under windows, you can use the Start \ Programs \ MPICH2 \ wmpiregister.exe and save username and password:Ĭ:\Program Files\MPICH2\bin\wmpiregister.exe See the for details and hints like minimal installation for nodes. mpiexec.exe, also found in the bin directory, is used to start MPICH2 jobs. The bin directory contains smpd.exe which is the MPICH2 process manager used to launch MPI programs. The mpich2 dll(s) are copied to the Windows\system32 directory. You must install mpich on all nodes (computers of the cluster). This will install MPICH2 to C:\Program Files\MPICH2. The installer requires Administrative rights to install the smpd service. So, you can easily convert c examples to pascal.

The MPICH2 lazarus package contains the bindings (= pascal translations of the c header files), which allows pascal programs to use the same variables and functions as c programs would do. This means, MPICH must be installed on every machine. MPICH is a library plus tools to run a ring of daemons. The latest version MPICH2 implements the MPI-2 standard. MPICH is a free implementation of MPI (Message Passing Interface) for distributed memory applications. 2.4 Create the first Free Pascal MPI program.

2.3 Get/Compile the MPI bindings for Free Pascal / Lazarus.
