SUPRENUM software for the symmetric eigenvalue problem
The efficient use of the SUPRENUM computer calls for a careful choice of adequate algorithms and an implementation taking into account the special characteristics of a parallel computer with distributed memory. To demonstrate these facts, well-known algorithms solving the symmetric eigenvalue problem are presented, parallelized in particular for the SUPRENUM machine.The main problems arise in the amount of communication calls, and ways are shown to reduce this amount by using block algorithms rather than the usual ones
