The biggest Icare case ever completed at IEEA is 230 000 unknowns large. The monostatic RCS of a rough surface sample has been computed in less than 2 days. 128 CPUs were used to inverse a 400 Gb large matrix. The best part is that this cluster wasn’t physically at IEEA : it was based on Amazon EC2 instances. For the entire simulation, this on-demand cluster costs less than 100 euros. IEEA can assist the users of the parallel version to run Icare on such clusters. Please contact us for more information.
Last minute update : the new record is now 300 000 unknowns. The same virtual cluster has been used to factorize a 780 Gb matrix in about 40 hours. The overall resolution time was 60 hours.
