About ExCL

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 Advanced Computing Systems Research Section at ORNL. ExCL researchers investigate architectures such as multi- and many-core processors, Graphics Processing Units (GPUs), non-volatile memory systems, Field Programmable Gate Arrays (FPGAs), and highly heterogeneous systems. See our current resources at ExCL Resources.

Over the years, ExCL has adapted to the needs of the researchers of the Future Technologies Group (now the Advanced Computing Research Section) and their collaborators. Now, ExCL is open to computer science researchers throughout the world. ExCL aims at being an open and collaborative platform where cutting edge computing research takes place.

ExCL is a production research laboratory. It provides the flexibility of pure research systems, while offering a production quality service and support. This support also includes an active role by ORNL ACSR researchers in that these researchers can share their expertise and knowledge about the system and technologies with the users.

If you need something else, please let us know. If your workflow cannot be accommodated in the current ExCL infrastructure, also contact us and we will try to work it out. ExCL staff is excited to try new architectures and designs and to help researchers to implement new workflows. Contact us at to see how we can fit in with your research.

Happy computing!
