The models and languages most widely used for distributed systems programming (such as ADA, CSP, and OCCAM) do not explicitly consider the process execution site, they assume a synchronous communication scheme of “rendezvous” style, and require that each process recognize the names of their interlocutors. JOYCE+ is a modification of ...

Speculative thread-level parallelization is a promising way to speed up codes that compilers fail to parallelize. While several speculative parallelization schemes have been proposed for different machine sizes and types of codes, the results so far show that it is hard to deliver scalable speedups. Often, the problem is not ...

Shared caches have become, de facto, the common design choice in current multi-cores, ranging from embedded devices to high-performance processors. In these systems, requests from multiple applications compete for the cache resources, degrading to different extents their progress, quantified as the performance of individual applications compared to isolated execution. The ...

Small files are known to pose major performance challenges for file systems. Yet, such workloads are increasingly common in a number of Big Data Analytics workflows or large-scale HPC simulations. These challenges are mainly caused by the common architecture of most state-of-the-art file systems needing one or multiple metadata requests ...

Concurrent Big Data applications often require high-performance storage, as well as ACID (Atomicity, Consistency, Isolation, Durability) transaction support. Although blobs (binary large objects) are an increasingly popular storage model for such applications, state-of-the-art blob storage systems offer no transaction semantics. This demands users to coordinate data access carefully in order ...

Large-scale scientific experiments increasingly rely on geo-distributed clouds to serve relevant data to scientists worldwide with minimal latency. State-of-the-art caching systems often require the client to access the data through a caching proxy, or to contact a metadata server to locate the closest available copy of the desired data. Also, ...

As the number of cores increases in both incoming and future chip multiprocessors, coherence protocols must address novel hardware structures in order to scale in terms of performance, power, and area. It is well known that most blocks accessed by parallel applications are private (i.e., accessed by a single core). ...

In this paper we study the universal stability of undirected graphs in the adversarial queueing model for packet routing. In this setting, packets must be injected in some edge and have to traverse a path before leaving the system. Restrictions on the allowed types of path that packets must traverse ...

The same flexibility that makes dynamic scripting languages appealing to programmers is also the primary cause of their low performance. To access objects of potentially different types, the compiler creates a dispatcher with a series of if statements, each performing a comparison to a type and a jump to a ...

In Thread-Level Speculation (TLS), speculative tasks generate memory state that cannot simply be combined with the rest of the system because it is unsafe. One way to deal with this difficulty is to allow speculative state to merge with memory but back up in an undo log the data that ...

Abstract: Reductions are important and time-consuming operations in many scientific codes. Effective parallelization of reductions is a critical transformation for loop parallelization, especially for sparse, dynamic applications. Unfortunately, conventional reduction parallelization algorithms are not scalable. In this paper, we present new architectural support that significantly speeds-up parallel reduction and makes ...

Classifying memory accesses into private or shared data has become a fundamental approach to achieving efficiency and scalability in multi- and many-core systems. Since most memory accesses in both sequential and parallel applications are either private (accessed only by one core) or read-only (not written) data, devoting the full cost ...

To meet the demand for more powerful high-performance shared-memory servers, multiprocessor systems must incorporate efficient and scalable cache coherence protocols, such as those based on directory caches. However, the limited directory cache size of the increasingly larger systems may cause frequent evictions of directory entries and, consequently, invalidations of cached ...
