Al Geist is a Corporate Research Fellow at Oak Ridge National Laboratory
(ORNL), where he leads the 35 member Computer Science Research Group.
He is one of the original developers of PVM (Parallel Virtual Machine),
which became a world-wide de facto standard for heterogeneous distributed
Al was actively involved in both the MPI-1 and MPI-2 design teams and more
recently the development of FT-MPI, a fault tolerant MPI implementation.
Today He leads a national Scalable Systems Software effort, involving all
the DOE and NSF supercomputer sites, with the goal of defining standardized
interfaces between system software components. Al is co-PI of a national
Genomes to Life (GTL) center. The goal of his GTL center is to develop
new algorithms, and computational infrastructure for understanding protein
machines and regulatory pathways in cells. He heads up a project developing
self-adapting, fault tolerant algorithms for 100,000 processor systems.
In his 20 years at ORNL, he has published two books and over 190 papers
in areas ranging from heterogeneous distributed computing, numerical
linear algebra, parallel computing, collaboration technologies, solar
energy, materials science, biology, and solid state physics.
