The research is carried out through a number of national collaborativeprojects. Scientific software for high-performance platforms and computationalGrids with a focus on software libraries is developed with support fromthe Los Alamos Computer Science Institute(LACSI). LACSI is a joint Institute between LosAlamos National Laboratories, and five academic partners, RiceUniversity, University of Houston, Universityof Illinois at Urbana/Champaign, Universityof New Mexico and the University ofTennessee with Rice as the lead institution. LACSI is funded by theDepartment of Energy under itsAcceleratedStrategic Computing Initiative. Research in tools and techniquesfor building adaptive, Grid-aware libraries is an integral part of theGridApplication Development Software (GrADS) project funded by the NationalScience Foundation (NSF) under its NextGeneration Software initiative. The development of scientific softwarelibraries for computational Grids is also in part supported by theAlliancepartnership, one of two NSF funded Partnershipsfor Advanced Computational Infrastructure. Currently, our effort isfocused on developing adaptiveFFTsoftware. The Simulation DataBase (SimDB) project aimes at creating a software environment for simulationand analysis of molecular dynamics trajectory data in a Grid environment.It is pursued jointly with the Institue for Molecular Design (IMD) at theUniversity of Houston. This effort is funded in part through theNationalPartnership for Advanced Computational Infrastructure (NPACI).
Dr Johnsson's research group was an early participant in the Globusproject and demonstrated the first MPI application codes using theGlobus toolkit at SC97 using facilities at the San Jose conference site,at the University of Houston, ParallelDatorCentrum(PDC) in Stockholm, Sweden, the newly established TexasGigaPoP, a joint University of Houston, Rice University and BaylorCollege of Medicine project, and the Internet2,Nordunetand Sunet networks. At Alliance'98 Dr Johnsson's group participated in the demonstration of interactive,distributed, shared virtual environments with five institutions, NCSAat the University of Illinois Urbana/Champaign, the ElectronicVisualization Laboratory at the University of Illinois Chicago, theUniversityof Utah, the University of Houston and PDC. This demonstrationused virtual reality equipment at all five institutions and the Internet2,Nordunet and Sunet networks and the Startapgateway. In 2000, a demonstration of computational steering was carriedout at iNET2000 in Yokohama using virtual reality equipment at the conferencesite and high-performance computers at PDC and University of Houston, andthe APAN connection in addition to Internet2, Nordunet, Sunet, Startap,and the Texas GigaPoP. Dr Johnsson's interest in Grids lead to theparticipation in the formation of the USGridForum and active involvement in establishing the EuropeanGrid Forum that merged in October 2000 to form the GlobalGrid Forum. Dr Johnsson still maintains an interest in computercommunications network routing, and fast algorithmsforproblems with long range forces with applications in astrophysics,computationalchemistry and electromagnetics, parallel implementationof fast Legendre and spherical transforms and run--timepartitioningof data structures for load--balance in parallel and distributed systems.
Dr. Johnsson joined the University of Houston in 1995 after having servedas Director of Computational Sciences of Thinking Machines Corp. for eightyears. While with Thinking Machines Corp., Dr. Johnsson initiated the designof a register oriented instruction set for the Connection Machine systemsCM-2 and CM-200 and lead the development of the first comprehensive, commercialstrength, scalable scientific library for parallel architectures for theConnection Machine CM-2, CM-200, and CM-5 systems, the CMSSL (ConnectionMachine Scientific Software Library). Johnsson also lead the developmentof several communications functions for these systems. Since the fall of2000 Dr Johnsson is also affiliated with the Departmentof Numerical Analysis and Computer Sciences at the RoyalInstitute of Technology , Stockholm, Sweden where he also serves asDirector of ParallelDatorCentrum, the lead Center for High-Performance Computation and Visualizationfor academic institutions in Sweden.
Dr Johnsson has served on the faculties of the CaliforniaInstitute of Technology(Caltech), YaleUniversity and Harvard University.Dr. Johnsson introduced the first courses in parallel computation at Caltech,Yale University and Harvard University. Dr. Johnsson has authored or co-authoredover 100 journal and conference paperson variousaspects of parallel computation and served on several program committees.Dr. Johnsson has served on the Board of the ComputerResearch Association, CRA, and the UniversitiesSpace Research Association's , USRA's, Science Councils for ICASEandCESDIS.
