Monte Carlo eXtreme (MCX)

_{* best viewed on non-IE browsers}

Monte Carlo eXtreme, or MCX, is a Monte Carlo simulation software for photon migration in 3D turbid media. It uses Graphics Processing Units (GPU) based massively parallel computing techniques and is extremely fast compared to traditional CPU-based simulations. Using an nVidia 8800GT graphics card (14MP/114Cores), the acceleration is about 300x~400x with over 1700 parallel threads; this ratio can be as high as 700x on a high-end GTX 295 GPU (multiply by another 2x if both GPUs on GTX295 are used).
MCX was developed by Qianqian Fang at the [Photon Migration Lab], [Martinos Center for Biomedical Imaging], [Massachusetts General Hospital (Harvard Medical School)].
Details of this software can be found in the following paper:

[2009/10/21] The paper describing this software is now published online at [Optics Express website]. The abstract and PDF can be browsed from [this link]. Also, support for Windows is now available. Executable will be uploaded and please check out here.
[2009/10/20] The first public release of MCX, version 0.2 beta, is now ready for download. Both binary and source code are provided. To get started, please checkout the online documentation. Please let me know if you have any feedback or suggestions. Ideas on new features or collaborations are welcome!
[2009/05/01] The software package is currently under a series of internal tests for processing real application data. We will keep you posted when the binary software package is ready for public test.
