Speculative Shared -Memory Architectures
… and parallel codes. We propose a speculative shared-memory system to extract parallelism from codes for which today's parallelizing compilers fail. We distance ourselves from the existing literature by targeting scalability and modularity: Our hierarchical approach largely abstracts away the …

Analyzing Threads for Shared Memory Consistency
… of the same programs executing under a relaxed memory model. Specifically, we observe an average slowdown of 10% on an Intel Xeon platform, with slowdowns of 7% or less for 7 out of 10 benchmarks. On an IBM Power3 platform, we observe an average slowdown of 26%, with slowdowns of 7% or less for …

Asynchronous algorithms for shared memory machines
… computation, we introduce several asynchronous shared memory machines and design asynchronous algorithms for those machines. We first model asynchronous protocols for communication across unreliable channels using finite-state machines communicating via an unreliable shared memory. We establish …

Distributed shared memory for virtual environments
… to program, by designing a suitable distributed shared memory system. To be usable, the system must keep latency to a minimum, as virtual environments are very sensitive to it. The resulting design is push-based and non-consistent. Another requirement is that the system should be scaleable, over …

Ribbons: A Partially Shared Memory Programming Model
… mechanisms exist for efficient isolation of heap memory. This dissertation develops a new memory programming model known as ribbons to enable fine-grained isolation of heap memory. Ribbons is a shared memory programming model that allows for more implicit sharing of memory than multiprocessing yet …

Views and consistencies in distributed shared memory
… knowledge of spatial locality in the sharing of memory objects. An access graph is used to capture the sharing relationship among processes via the shared objects. We show that if accesses in all cycles are 'properly' synchronized, then the execution is guaranteed to be sequentially consistent. …

Rebound: Scalable checkpointing for coherent shared memory
… schemes that have been proposed for small shared-memory machines do not scale. Scalability barriers include global operations, work lost to global rollback, and inefficiencies in imbalanced or I/O-intensive loads. Scalable checkpointing requires tracking inter-thread dependences and …

Parallel architectural simulations on shared memory multiprocessors
… excessive amounts of processing power and memory. One way to meet these requirements of detailed computer simulations is to execute them on multiprocessors.

A Shared Memory System for Fresh Breeze
The Shared Memory System (SMS) for Fresh Breeze, a multiprocessor chip guided by modular programming principles, provides a global space from which all the fresh breeze processors access chunks of memory. The SMS supports the operations of: obtaining unique identifiers for new chunks; storing a …

Shared Memory Abstractions for Heterogeneous Multicore Processors
… multicore processors with Explicitly Managed Memory (EMM) hierarchies are one such experimental design which has the potential for high performance, but at the cost of great programmer effort. EMM processors have cores that are divorced from the normal memory hierarchy, thus the onus is on the …

Some Issues in General-Purpose Shared Memory Multiprocessing: Parallelism Exploitation and Memory Access Combining (Shared Memory Machine, Automatic Restructuring)
The use of automatic program restructuring and memory access combining for "general-purpose" large scale shared memory machine is investigated.

Tunable shared-memory abstractions for distributed-memory systems
Distributed memory multiprocessor architectures offer enormous computational power, by exploiting the concurrent execution of many loosely connected processors. Yet, such scalability is not without price. Interface delays and low interconnection bandwidth to the distributed memories make internode …

Preconditioned iterative methods on virtual shared memory machines
… Square Research Machine 1 (KSR1) is a virtual shared memory (VSM) machine. Memory on the KSR1 consists primarily of shared, physically distributed caches. Effective memory utilization of the KSR1 is studied within this thesis. Special emphasis is laid upon how best to optimize iterative Krylov …

Shared memory abstraction: new approach under high concurrency conditions
In the current dissertation an implementation of shared memory abstraction on top of contemporary multi-core and many-core clusters has taken place. The results of the presented research effort are mainly depicted in the implementation of the cluster middleware platform Pleiad. Pleiad is a …

The raven kernel: a microkernel for shared memory multiprocessors
… is a small, lightweight operating system for shared memory multiprocessors. Raven is characterized by its movement of several traditional kernel abstractions into user space. The kernel itself implements tasks, virtual memory management, and low level excep-tion dispatching. All thread …

Automatic data aggregation for software distributed shared memory systems
Software Distributed Shared Memory (DSM) provides a shared-memory abstraction on distributed memory hardware, making a parallel programmer's task easier. Unfortunately, software DSM is less efficient than the direct use of the underlying message-passing hardware. The chief reason for this is that …
