Performance Analysis of Electromagnetic Field Application on Large SMP Node

In the scope of the COLOC project we worked on understanding scalability issues of the efield application on a large shared memory system. Our analysis with above mentionned tools highlighted a potential bandwidth bottleneck. This problem can usually be tackled by the mean of threads and data mapping on respectively the machine cores and the memories. Unfortunately, those techniques can't be applied with this (closed source) application since the system does not allow to monitor memory accesses and traffic on the system.
