ABOUT THE MARTINOS CENTER IT INFRASTRUCTURE

The Center’s IT infrastructure consists of over 300 Linux workstations and 150 Windows and Macintosh desktops in offices and labs owned by individual research groups. There is a server farm with over 70 Linux servers that handles central storage, email, web, print, specialized processing and other shared services. The overall storage capacity of the center, including disks in local workstations and central storage, exceeds 1.5 petabytes.

The Center has a 100-node computing cluster for batch analysis jobs. Each node consists of two Quad Core Xeon E5472 3.0 GHz CPUs with 32GB of RAM, which together equal a total of 1024 compute cores available for batch jobs. Each node is connected by both a 1 GBit/s Ethernet link and a 20 GBit/s DDR Infiniband backplane. The Infiniband connection is used by parallelized jobs using MPI (message passing interface) to utilize multiple cores.

The IT facilities are supported by a small IT staff comprising one full-time PhD-level manager, who directs two full-time system administrators and a part-time support technician. The Center also has three full-time programmers who support in-house-developed software for data analysis and management. Available commercial software includes AVS (Advanced Visual Systems, Waltham, MA), MATLAB (The MathWorks, Natick, MA) and MEDx (Sensor Systems, Sterling, VA) for general-purpose computation, simulation and image analysis; and XWIN-NMR (Bruker BioSpin), Origin (OriginLab Corp., Northampton, MA), Nuts (Acorn NMR, Livermore, CA) for analysis of NMR spectra and the Siemens IDEA development environment for pulse sequences and image reconstruction software (Siemens, Erlangen, Germany). A substantial level of internal software development for image and data analysis is ongoing, using LAMP, C, C++, Java, FORTRAN, Ruby, Python, Perl and TCL/TK.

For high-performance image reconstruction the center is equipped with a Dell PowerEdge R910 server with four 10-core Intel Xeon E7-4850 processors and 1TB of quad ranked, DDR3 RAM. The center also has three Dell PowerEdge R910 with four 8-core Intel Xeon X7560 processors and 256GB of RAM.
