There are problems in Science and Engineering which require a higher computing power than that currently available on a single machine. To overcome this limit it may be possible to exploit the aggregate capabilities of several computes (metacomputing). In a metacomputer, machines of different power (PCs, workstations, parallel computers, etc.) are linked together and used as a single powrful computer (1). As a case tudy, a quantum dyanmics application concerned with the intetration of a time-independent Schrodinger equation is considered for parallelization on a metacomputer. Vector and paralle versions of this appliction have already been implemented on a vector multiporcessor and on an nCUBE 2 (5) and an IBM SP2 parallel systems. To further increase the dimensionality of the problem however, we cannot rely on the insufficient computing power of the above mentioned machines. To overcome these limits we have restructured the RIOS application so that it can run on a metacomputer consisting of three different platforms linked by a local area network.
