Continuing improvements in the scale of many-core platforms are accompanied by increased asymmetry in their memory architectures. Such NUMA architectures, however, require systems software that understands this asymmetry to attain high levels of performance, leading to significant work in optimizing operating systems like Linux and Windows to increase locality of access to memory nodes and to consider...
Recent hardware advances are creating multi-core systems with heterogeneous functionality. This paper explores how applications and middleware can utilize systems comprised of processors specialized for communication vs. computational tasks. The C-CORE execution environment enables applications, through middleware and underlying system functionality, to utilize both the computational capabilities...
Our past research with configurable operating system abstractions has developed a model and implementation of adaptive multiprocessor operating systems for improved application performance. Adaptive locks are one such kernel component where lock adaptations are performed for each application program to suit its dynamic locking pattern. The paper compares and evaluates two different methods for performing...
