Block matrix multiplication in a client server computing environment: experiments with Netsolve

We address synchronization issues of some block matrix multiplication algorithms in a distributed computing environment. We discuss performance behavior of a client/server implementation of these algorithms focusing on the most appropriate version which delivers the minimum synchronization overhead. Numerical experiments are carried out using the NetSolve distributed computing system.
