MESSAGE PASSING MODEL
MPICH implementations
Section contributed by IFIN-HH
Proposed as a freely available and portable implementation of the MPI standard, MPICH has evolved along with it, from the MPICH1 implementation [mpc1] (fulfilling MPI-1 specifications and partially supporting some MPI-2 features like the parallel I/O), to MPICH2 [mpc2], which is moreover fully compatible with the MPI-2 version of the standard. Although the development of the MPICH1 was frozen since 2005 to the 1.2.7p1 version, with the intention to be replaced with MPICH2, it continues to be the most used MPI implementation worldwide.

Open MPI
CMSLTM @IMBB (NEURON ParallelContext)
Preferred MPI environment is OpenMPI (openmpi_gcc-1.4.3). NEURON was compiled with parallel support (MPI) using the gcc compiler:
./configure --without-iv --with-paranrn --prefix=/home/gkastel/src/nrn-7.1
We used NEURON's ParallelContext to distribute the simulation of each neuron to different nodes evenly.
