The Experimental Computing Laboratory

The Experimental Computing Laboratory (ExCL) was established in 2004 with the goal of providing application users and computer scientists with access to systems with leading edge architectures and software.  ExCL is managed by the ORNL Future Technologies Group.  ExCL researchers investigate architectures such as multi- and many-core processors, Graphics Processing Units (GPUs), Multi-Threaded Array Processors (MTAPs), and Field Programmable Gate Arrays (FPGAs).  Most ExCL hardware is located in a large access-controlled server room in the JICS Building at ORNL (Building 5100), near the Future Technologies Group offices.
