Abstract

The Flosolver parallel computer designed and built at NAL for fluid dynamics problem solving is described. The computer has two nodes each having four processors based on Intel 8086-8087 chips. In each node one of the processors acts as host and has access to a section of the13; private memory of the remaining three processors through the Multibus.Inter-node communication is done using parallel ports. Synchronization and inter-processor communication is done by passing the message through a global memory. Prior to execution the host processor loads13; the absolute codes from a disk to the respective processors. Several fluid dynamical problems of practical interest have been programmed on Flosolver using concurrent algorithms, and show that it is comparable13; in speed with mainframes available in the country.
