Operating system support for execution time budgets for thread groups

Compile/Run-Time Support for Thread Migration

This paper describes a generic mechanism to migrate threads in heterogeneous distributed environments. To maintain high portability and flexibility, thread migration is implemented at language level. At compile-time, a preprocessor scans the C and C++ programs to build thread state, detects possible thread migration points, and transforms the source code accordingly. Run-time support helps migr...

Operating System support for Java

Over the last 15 years a number of persistent language systems have been produced whose implementation relies on the persistence mechanisms provided by an underlying operating system. We have produced an operating system called Grasshopper expressly designed to support orthogonally persistent systems. In this paper we demonstrate how the mechanisms provided by Grasshopper may be used to impleme...

Operating System Support for Resilience

This paper is concerned with improving the resilience of mission-critical applications to a wide variety of failures, errors, and malicious attacks. A number of approaches have been proposed in the literature based on fault tolerance provided through replication of resources. In general, these approaches provide graceful degradation of performance to the point of failure but do not guarantee pr...

Operating System Support for IPNoSys

The IPNoSys is an architecture that exploits the advantages of NoCs as parallel communication, reusability and scalability to transform the routers in processing elements building a packet-driven architecture that processing while routing the packets. This represents a paradigm break of traditional NoC-based MPSoC systems, which there is the separation between computation and communication. Wit...
