Efficient management of shared on-chip resources such as the shared level 2 (L2) cache has become an important problem with the emergence of chip multiprocessors (CMPs). Partitioning the shared cache in chip multiprocessors (CMPs) among concurrently executing applications can provide important benefits such as throughput improvement, fairness guarantees, and quality of service (QoS) enhancements....
Thread mapping and data mapping are two important problems in the context of NoC (network-on-chip) based CMPs (chip multiprocessors). While a compiler can determine suitable mappings for data and threads, such static mappings may not work well for multithreaded applications that go through different execution phases during their execution, each phase with potentially different data access patterns...
One of the critical problems associated with emerging chip multiprocessors (CMPs) is the management of on-chip shared cache space. Unfortunately, single processor centric data locality optimization schemes may not work well in the CMP case as data accesses from multiple cores can create conflicts in the shared cache space. The main contribution of this paper is a compiler directed code restructuring...
