Abstract

Using the Linda system, a parallel matrix multiplication program was written. This program uses N² + 1 ICAP processors to compute the product of two N x N matrices. Due to the computational simplicity of matrix multiplication, a single ICAP processor running a sequential matrix multiplication program was faster than the Linda program. The computational complexity for which the Linda system becomes faster than a single ICAP processor was found. This was done by assuming that N² computations still needed to be done, each requiring the row of one matrix and the column of another. Once a processor acquires these two arrays, an operation was simulated by running a delay loop. By increasing the size of the delay loop, more complex operations could be "simulated."
