Systems Laboratory

About the Systems Laboratory

Marquette's Systems Laboratory, under the direction of Dr. Dennis Brylow in the Department of Mathematics, Statistics, and Computer Science, is housed on the third floor of Cudahy Hall.

The lab creates new tools and methods for building and studying complex computer systems. Our emphasis is on embedded, real-time, and network systems, with strong ties to the electrical and computer engineering community, and the computer science education community. Current projects include:

1. Experimental Embedded Networking Platform. Creation of laboratory infrastructure and software for research and education in the area of embedded networking appliances, particularly wireless routers and IP telephony. Collaboration with Cisco Systems Advanced Research Division.

2. Experimental Embedded Operating System Laboratory. Creation of laboratory infrastructure and software for research and education in area of embedded operating systems. Collaboration with University of Buffalo and University of Mississippi, with funding from the National Science Founcation.

3. Embedded Software Transactional Memory. Exploration of an innovative transactional memory model for guaranteeing process synchronization in embedded operating systems. Collaboration with Intel Research.

The Systems Lab will host three undergraduate REU (Research Experience for Undergraduates) students in summer 2010, funded by the MU's College of Arts and Sciences. They will be working on ports of the Embedded Xinu operating system to new embedded platforms, embedded network emulation, and multicore embedded systems.

See the MSCS Research Labs page for more research laboratories in our department.

Lab Equipment

The Systems Laboratory is populated with dual-headed Linux boxes running the latest version of Fedora Linux. Other workstations in the lab include a dual-core Apple G5 running OS X, and several multi-core boxes for higher-end computation.

The Xinu Laboratory component of the Systems Lab includes a pool of 24 WRT54GL wireless routers organized into a managed embedded backend pool, as well as smaller quantities of half a dozen other router types. Embedded development kits available include the Freescale/Motorola 68HC12 Dragon12 board, the Atmel AT91 Series ARM Thumb AT91EB40A board, the ATmega169 Butterfly, a Zilog Z86 Emulator Z86CCP01ZEM, and the Zilog Z8 Encore XP Dev Kit Z8F04A28100KIT-C.

The Systems Lab includes both a private research network with our own gateway and firewall, and connections to each of the MSCS department production networks. The Lab also hosts Subversion, Trac, and Web service for the Marquette Student ACM Chapter, the Marquette University Linux Users Group, and a stratum 2 NTP server for campus.
