Annual report of Argonne National Laboratory's Chemical Technology (CMT) Division. In this period, CMT conducted research and development in areas that include the following: (1) high-performance batteries--mainly lithium-alloy/metal sulfide and sodium/sulfur; (2) aqueous batteries (lead-acid, nickel/iron, etc.); (3)advanced fuel cells with molten carbonate or solid oxide electrolytes; (4) coal utilization, (5) methods for recovery of energy from municipal waste; (6) methods for the electromagnetic continuous casting of steel sheet; (7) techniques for treatment of hazardous waste such as reactive metals and trichloroethylenes; (8) nuclear technology related to waste management.

In the application software development of the SUPRENUM project (the German supercomputer project) many parallel grid-oriented algorithms are being programmed, especially multigrid and computational fluid dynamics codes. As the communication tasks are similar, a central SUPRENUM communications library with subroutines covering all communication requirements of the applications programs has been created. By implementing versions of the library for the Intel iPSC hypercube and the planned SUPRENUM machine, full portability of the applications software has been achieved.
