While clusters of commodity servers and switches are the most popular form of large-scale
parallel computers, many programs are not easily parallelized for execution upon them. In …

The computer industry has adopted multi-threaded and multi-core architectures as the clock
rate increase stalled in early 2000's. It was hoped that the continuous improvement of single …

With the right techniques, multicore architectures may be able to continue the exponential
performance trend that elevated the performance of applications of all types for decades …

In this paper we present a processor microarchitecture that can simultaneously execute
multiple threads and has a clustered design for scalability purposes. A main feature of the …

Speculation with transactional memory systems helps pro-grammers and compilers produce
profitable thread-level parallel programs. Prior work shows that supporting transactions that …

This research demonstrates that coming support for hardware transactional memory can be
leveraged to significantly reduce the cost of implementing true speculative multithreading. In …

Most systems that support speculative parallelization, like hardware transactional memory
(HTM), do not support nested parallelism. This sacrifices substantial parallelism and …

Thread level speculation (TLS) and transactional memory (TM) are both proposed to
address the problem of productivity in multi-core era. Both of them require similar underlying …

Master/Slave Speculative Parallelization (MSSP) is an execution paradigm for improving the
execution rate of sequential programs by parallelizing them speculatively for execution on a …

This work studies the interplay between multithreaded cores and speculative parallelism
(eg, transactional memory or thread-level speculation). These techniques are often used …
