Heterogeneous Distrihuled Coiiipuliiig 



Ogbl 



The PVM (Parallel Virtual Machine) soft- 

 ware permits a heterogeneous collec- 

 tion of networked Unix machines (serial, 

 vector, or parallel) to be used as a sin- 

 gle large parallel computer This public- 

 domain software is now used at hun- 

 dreds of sites worldwide. 



project is cofunded by DOE's Fusion Energy pro- 

 gram and is an important component of the 

 National Energy Strategy. 



By the end of FY 1992 DOE supported 14 computational 

 projects. No new computational projects or Grand 

 Challenges were started in FY 1993 due to lack of 

 funds. In FY 1994, the DOE expects to evaluate the 

 existing projects and may initiate new projects to bal- 

 ance the program in response to the goals and objec- 

 tives of the DOE HPCC Program. 



Software Tools 



Projects were initiated in: object oriented data base 

 technology (applied to and cofunded with the 

 Superconducting Supercollider), large spatial databas- 

 es, distributed computing technologies, and software 

 environments. 



Computational Techniques 



The DOE initiated projects on computational techniques 

 applied to catalysis, drug design, and in chemistry and 

 the materials sciences in cooperation with private sector 

 firms. 



High Performance Computing Research Centers 

 (HPCRC) and Advanced Computing Resources 



Two HPCRCs were created in FY 1992, at Los Alamos 

 National Laboratory (LANL) and at Oal< Ridge National 

 Laboratory (ORNL), involving industrial and university 

 partnerships as well as cofunding from other DOE pro- 

 grams. These HPCRCs conduct research in all HPCC 

 Program component areas; operate massively parallel 

 high performance computing prototypes (a Thinking 

 Machines Inc. CMS at LANL and an Intel Corp. Paragon 

 at ORNL); perform computational investigations in glob- 

 al climate research, environmental groundwater trans- 

 port modeling, and in materials sciences calculations; 

 and provide HPCS resources for the other computation- 

 al research projects described above. The HPCRC at 

 LANL is also a partner in an NSF-sponsored Science 

 and Technology Consortium. The Serial #1 Kendall 

 Square system was installed at the ORNL HPCRC 

 where it will be evaluated on energy applications.
