Impulse is a new memory system architecture that adds two important features to a traditional memory controller. First, Impulse supports application-specific optimizations through configurable physical address remapping. By remapping physical addresses, applications control how their data is accessed and cached, improving their cache and bus utilization.(More)
Effects of aromatherapy (odorless condition, lavender, and hiba oil) on mood and anxiety were investigated in 14 female patients who were being treated with chronic hemodialysis. A control period consisting of natural hospital smells was established before each test session, and then aromatic test conditions were systematically evaluated for odorless(More)
OBJECTIVE The aim of this study was to investigate the influence of odorant concentration on the olfactory event-related potential (OERP). METHODS OERP were evaluated in 8 men and 8 women (17-34 years of age) in response to 4 concentrations of vanillin (7, 28, 56 and 84% v/v). Sixteen presentations of each concentration (stimulus duration 200 ms, interval(More)
Because irregular applications have unpredictable memory access patterns, their performance is dominated by memory behavior. The Impulse conngurable memory controller will enable signiicant performance improvements for irregular applications, because it can be con-gured to optimize memory accesses on an application-by-application basis.

Minimizing communication latency in message passing multiprocessing systems is critical. An emerging problem in these systems is the latency contribution costs caused by the need to percolate the message through the memory hierarchy (at both sending and receiving nodes) and the additional cost of managing consistency within the hierarchy.

This paper presents the Impulse adaptable memory system , which allows applications to make efficient use of cache space and bus bandwidth. Impulse has a con-figurable memory controller that allows applications to remap data in the memory system. As a result, applications can control how their data is accessed, organized, and cached. We describe the current(More)
