Automatic scalable atomicity via semantic locking
In this paper, we consider concurrent programs in which the shared nsists of instances of linearizable ADTs (abstract data types). We present an automated approach to concurrency ...

MPI+Threads: runtime contention and remedies
Hybrid MPI+Threads programming has emerged as an alternative model to the “MPI everywhere” model to better handle the increasing core density in cluster nodes. While the MPI s...

Distributed memory code generation for mixed Irregular/Regular computations
Many applications feature a mix of irregular and regular computational structures. For example, codes using adaptive mesh refinement (AMR) typically use a collection of regular b...

Low-overhead software transactional memory with progress guarantees and strong semantics
Software transactional memory offers an appealing alternative to locks by improving programmability, reliability, and scalability. However, existing STMs are impractical because t...

The lock-free k-LSM relaxed priority queue
We present a new, concurrent, lock-free priority queue that relaxes the delete-min operation to allow deletion of any of the ρ+1 smallest keys instead of only a minimal one, wher...

The lazy happens-before relation: better partial-order reduction for systematic concurrency testing
We present the lazy happens-before relation (lazy HBR), which ignores mutex-induced edges to provide a more precise notion of state equivalence compared with the traditional happe...

Towards batched linear solvers on accelerated hardware platforms
As hardware evolves, an increasingly effective approach to develop energy efficient, high-performance solvers, is to design them to work on many small and independent problems. I...

Are web applications ready for parallelism?
In recent years, web applications have become pervasive. Their backbone is JavaScript, the only programming language supported by all major web browsers. Most browsers run on desk...

Thread-level parallelization and optimization of NWChem for the Intel MIC architecture
In the multicore era it was possible to exploit the increase in on-chip parallelism by simply running multiple MPI processes per chip. Unfortunately, manycore processors’ greatl...
