1 Abstract-The Express Ring is a new architecture under investigation at the University of Southern California. Its main goal is to demonstrate that a slotted unidirectional ring with very fast point-to-point interconnections can be at least ten times faster than a shared bus, using the same technology, and may be the topology of choice for future shared-memory multiprocessors. In this paper we...

The authors propose a protocol for improving the performance of noise-biased trapped-ion qubit memory by rebalancing noise bias in logical qubit. demonstrate that can reduce net error rate up to two orders magnitude realistic parameters.

We propose a protocol for oblivious transfer that is unconditionally secure under the sole assumption that the memory size of the receiver is bounded. The model assumes that a random bit string slightly larger than the receiver’s memory is broadcast (either by the sender or by a third party). In our construction, both parties need memory of size in (n2 2 ) for some < 12 , when a random string o...

Building collaborative applications is still a challenging task. A collaborative application can be viewed as a class of distributed shared memory system. A distinctive property of these systems is their memory consistency model. In this paper, we argue that there is a relationship between different collaboration styles, on the one hand, and different memory consistency models, on the other. In...

Shared virtual memory is a software technique to provide shared memory on a network of computers without special hardware support. Although several relaxed consistency models and implementations are quite eeective, there is still a considerable performance gap between the \software-only" approach and the hardware approach that uses directory-based caches. Automatic update is a simple communicat...

ÐDirectory schemes have long been used to solve the cache coherence problem for large scale shared memory multiprocessors. In addition, tree-based protocols have been employed to reduce the directory size and the invalidation latency for a large degree of data sharing in the system. However, the existing tree-based protocols involve a very high communication overhead for maintaining a balanced ...

Attempts to cure breast cancer by adoptive cellular therapy (ACT) have not been successful. This is primarily due to the presence of tumor-induced immune-suppressive mechanisms as well as the failure of tumor-reactive T cells to provide long-term memory responses in vivo. To address these clinically important challenges, we developed an ex vivo protocol for the expansion of tumor-reactive immun...

This paper describes the design of Jackal, a compiler-driven distributed shared memory implementation of the Java programming language. Our goal is to efficiently execute (unmodified) multithreaded Java programs on a cluster of workstations. Jackal consists of a native Java compiler and a runtime system that implements a distributed shared memory protocol for variable sized memory regions. The ...
