Mesh-based Monte Carlo, or MMC, is a Monte Carlo simulation package designed for simulating photon transport in 3D heterogeneous media. MMC can use a volumetric mesh to represent a complex domain, making it computationally and memory efficient.
MMC supports multi-threading based parallel computing. You can obtain a nearly linear speed-up when using more CPU cores in your simulation. Starting from version 0.8, MMC also supports the Single-Instruction Multiple-Data (SIMD) parallelism on modern CPUs, allowing MMC to take further advantage in parallel computing.
MMCLAB is the MATLAB mex version of the MMC software. It can be directly called inside MATLAB.
This is the 3rd release of our new time-based release strategy. We plan to announce 4 releases each year - one release per 3 months.

MMC/MMCLAB 1.0-RC2 is the second release candidate (RC) to the upcoming milestone, version 1.0, of MMC. It contains a number of bug fixes and four new forms of source types. The Makefile of the source code was also improved to support automatic nightly-build.
The v2017.2 release was improved upon the previous version, v2016.5 by fixing a list of bugs. They are:
Pre-compiled MMC binaries are provided for Windows, Linux and Mac OS. In all cases, a binary compiled with SSE4-accelerated ray-tracing algorithms is provided for each platform.
The best simulation speed can be typically achieved by using
mmc -M S -C 0 ....
One can recompile all binaries using an Intel C++ Compiler. It can generate binaries up to 25% faster than the equivalent binaries compiled with GCC.
Although MMC/MMCLAB can be executed independently once all input data (including mesh data) are provided, most pre- and post-processing scripts in both packages require the installation of Iso2Mesh Toolbox - a MATLAB based 3D mesh generator. Please browse http://iso2mesh.sf.net for download and installation information.
The default "SSE4" binaries require your computer to support SSE4 instructions. This can be determined by using the following command on Linux/MacOS
grep 'sse4' /proc/cpuinfo
or using a freeware "CPU-Z" on windows. If you attempt to run the SSE4 on an unsupported computer, you will get an error when executing the binary. In that case, you should recompile MMC using "make omp" command.
