This paper develops a coherence analysis framework based on incremental coherence simulation of actual reference traces, and shows that cache coherence traffic can be simulated with a considerable degree of accuracy for SPMD programs, as the invalidation traffic closely matches the corresponding hardware performance counters.

Improving WCET by applying worst-case path optimizations
REAL-TIME SYSTEMS, 34(2), 129–152.
author keywords: WCET; path-based optimizations; embedded systems
TL;DR:
This paper describes an approach to reduce the WCET by adapting and applying optimizations designed for frequent paths to the worst-case (WC) paths in an application and uses feedback from a timing analyzer to detect the WC paths in a function.

Enforcing safety of real-time schedules on contemporary processors using a virtual simple architecture (VISA)
25TH IEEE INTERNATIONAL REAL-TIME SYSTEMS SYMPOSIUM, PROCEEDINGS, pp. 114–125.
TL;DR:
A VISA variant is proposed that dynamically accrues the slack needed to facilitate speculation in the complex mode, eliminating the need to statically pad WCETs and thereby enabling VISA-style speculation even in highly-utilized systems.

Feedback EDF scheduling of real-time tasks exploiting dynamic voltage scaling
REAL-TIME SYSTEMS, 31(1-3), 33–63.
author keywords: real-time systems; scheduling; dynamic voltage scaling; feedback control
TL;DR:
A feedback control model is given to describe the feedback DVS scheduler, which is used to analyze the system's stability and the ability of the algorithm to save up to 29% more energy than previous work for task sets with different dynamic workload characteristics.

FAST: Frequency-aware static timing analysis
RTSS 2003: 24TH IEEE INTERNATIONAL REAL-TIME SYSTEMS SYMPOSIUM, PROCEEDINGS, pp. 40–51.
TL;DR:
Novel techniques for tight and flexible static timing analysis particularly well-suited for dynamic scheduling schemes are contributed, including a parametric approach towards bounding the WCET statically with respect to the frequency and an improved parametric model for improving existing DVS scheduling schemes.

Communication characteristics of large-scale scientific applications for contemporary cluster architectures
Vetter, J. S., & Mueller, F. (2003, September). JOURNAL OF PARALLEL AND DISTRIBUTED COMPUTING, Vol. 63, pp. 853–865.
TL;DR:
This paper examines the explicit communication characteristics of several sophisticated scientific applications, which, by themselves, constitute a representative suite of publicly available benchmarks for large cluster architectures by focusing on the Message Passing Interface (MPI) and by using hardware counters on the microprocessor.

author keywords: distributed mutual exclusion; middleware services; distributed resource allocation; concurrency services; hierarchical locking; peer-to peer protocols; scalability; large-scale distributed computing; distributed agreement; distributed transactions
TL;DR:
The objective of the work is to enhance middleware services to provide scalability of synchronization and to support state replication in distributed systems, and designed and implemented a middleware protocol that is a peer-to-peer protocol for multi-mode hierarchical locking, applicable to transaction-style processing and distributed agreement.

Handling irreducible loops: Optimized node splitting versus DJ-Graphs
ACM TRANSACTIONS ON PROGRAMMING LANGUAGES AND SYSTEMS, 24(4), 299–333.
author keywords: algorithms; languages; code optimization; compilation; control flow graphs; instruction-level parallelism; irreducible flowgraphs; loops; node splitting; reducible flowgraphs
TL;DR:
A method of optimized node splitting to transform irreducible regions of control flow into reducible regions is formally defined and its correctness is shown, which is superior to approaches previously published since it reduces the number of replicated nodes by comparison.
