Abstract :
A parallel factorization of a sparse multilevel representation of the EFIE impedance matrix is discussed. A nonblocking asynchronous communication protocol is used to transfer data between processors. Numerical examples demonstrate the performance and accuracy of the factorization on a distributed memory parallel cluster.
