Parallel SSOR preconditioning implemented on dynamic SMP clusters with communication on the fly

The paper presents a comparative analysis of parallel implementation of the preconditioned conjugate gradient method with the symmetric-successive over-relaxation preconditioner. Two parallel implementations of the matrix solver are compared. The first one is a message-passing version executed on a cluster of workstations. The other one is an efficient version simulated on a novel architecture of dynamically reconfigurable shared memory clusters with a new paradigm of inter-processor communication called communication on the fly. The presented example shows high suitability of the proposed architecture for fine grain numerical computations. It can be very useful in the simulation of physical phenomena described as numerical problems suitable for fine grain parallel execution.
