Eric Roman is a computer systems engineer at Lawrence Berkeley National Laboratory. He joined Berkeley Lab in 1999. From 2004-2006, Roman took leave to pursue a Ph.D. in physics at the University of California Berkeley where he performed ab initio simulations of nonlinear optical properties of semiconductors, spin transport in metals, and the anomalous Hall effect. He completed his doctoral dissertation entitled “Orientation Dependence of the Anomalous Hall Effect in 3D Ferromagnets” in 2010. His research at Berkeley Lab focuses on operating systems for high performance computing. He has participated in the development of Berkeley Lab’s Checkpoint/Restart (BLCR) since the start of the project in 2001. He wrote the initial requirements and implementation surveys before moving on to implement multithreaded checkpoints and restarts. He later implemented BLCR's support for files, pipes, on-the-fly compression of checkpoint files, and direct I/O. In 2008, he worked with Cluster Resources Inc. to add BLCR support to the Torque batch system. In 2003, Roman led a seminar on the Linux kernel attended by NERSC and Sandia-Livermore. In 2004, he organized the FastOS project “High-End Computing with K42.” He is currently working to optimize file I/O operations in BLCR and participates in Berkeley Lab's collaboration with the Berkeley ParLab.
