About me
Position
Currently I'm working at ICL as a Research Scientist 1 and Adjunct Assistant Professor at the University of Tennessee, Knoxville
Projects
Open MPI
Open MPI is a project combining technologies and resources from several other projects (FT-MPI, LA-MPI, LAM/MPI, and PACX-MPI) in order to build the best MPI library available. A completely new MPI-2 compliant implementation, Open MPI offers advantages for system and software vendors, application developers and computer science researchers.
FT-MPI
HARNESS (Heterogeneous Adaptive Reconfigurable Networked SyStem) is an experimental Metacomputing System aiming at providing a highly dynamic, fault-tolerant computing environment for high performance computing applications. To make the HARNESS system more accessible to the user community a HARNESS MPI API has been developed, known as FT-MPI.
MPICH-V
MPICH-V is a research effort with theoretical studies, experimental evaluations and pragmatic implementations aiming to provide a MPI implementation based on MPICH, featuring multiple fault tolerant protocols. MPICH-V provides automatic fault tolerant MPI library (i.e. a totaly unchanged application linked with the mpich-v library is a fault tolerant application).
