Best paper award in COSMIC workshop, held in conjuction with CGO 2013

The paper "Fast Dynamic Binary Rewriting to Support Thread Migration in Shared-ISA Asymmetric Multicores" authored by Giorgis Georgakoudis, Dimitris Nikolopoulos and Spyros Lalis won the best paper award at the International Workshop on Code Optimisation for Multi and Many Cores (COSMIC) held in conjunction with CGO 2013 in Shenzhen, China. Shared-ISA multi-cores comprise of ISA-asymmetric cores which share a common, baseline ISA but can also implement additional accelerating instructions. Thread migration for adaptivity at runtime is a key mechanism to support efficient scheduling in heterogeneous multi-cores. The paper presents binary rewriting methods and techniques to support thread migration between shared-ISA asymmetric cores, enabling code portability at the binary level. The proposed method shows good efficiency compared to non-portable, statically targeted code, giving the flexibility for higher-level scheduler optimizations.
