Data monitoring in high-performance clusters for computing applications

The shared memory in a LAN-like environment (SMiLE) project at Lehrstuhl fur Rechnertechnik und Rechnerorganisation, Technical University of Munich (LRR-TUM) investigates in high-performance cluster computing using system area networks. In the context of this project, a hardware monitor is being developed to observe the system area network (SAN) traffic. This hardware monitor is, therefore, capable of delivering detailed information about the run-time communication behavior of applications running on SMiLE clusters. The central part of this monitor consists of a content-addressable counter array managing a small working set of the most recently referenced memory regions.
