Message passing and bulk transport on heterogenous multiprocessors
Reto Achermann · Repository for Publications and Research Data (ETH Zurich) · 2014
The decade of symmetric multiprocessors is about to end.Due to physical limitations, individual cores cannot be made any faster and adding cores won't work anymore (dark silicon).Operating systems face the next big paradigm shift: systems are getting faster by exploiting specialized hardware leading to the era of asymmetric processors and heterogeneous systems.An ever growing count and the diversity of cores yields new challenges regarding scheduling and resource management.Multiple physical address spaces within single machines let them appear as a cluster-like system.
