Motivated by the challenges of scaling up memory capacity and fully exploiting the benefits of memory compression, we propose Buri, a hardware-based memory compression scheme, which simultaneously achieves cost efficiency, high performance, and ease of adoption. Buri combines (1) a self-contained, ready-to-adopt hardware compression module, which manages(More)
The emergence of big data analytics and the need for cost/energy efficient IT infrastructure motivate a new focus on data-centric designs. In this paper, we aim to better understand the design implications of data analytics systems by quantifying workload requirements and runtime dynamics. We examine four workloads representing big data analytics trends for(More)
Recent proposals using low-power processors and Flash-based storage can dramatically improve the energy-efficiency of compute and storage subsystems in data-centric computing. However, in a balanced system design, these changes call for matching improvement in the network subsystem as well. Conventional Ethernet-based networks are a potential(More)
A case of bilateral internal iliac artery aneurysms in association with an infrarenal abdominal aortic aneurysm is presented. The implications of surgical repair of these lesions are considered, particularly with reference to interruption of pelvic blood flow. Reimplantation of the inferior mesenteric artery is recommended when internal iliac artery flow is(More)
A study examining combined carotid endarterectomy and coronary artery bypass (CAB) outside the metropolitan or university hospital setting was performed. Over a 5-year period, 52 patients underwent carotid endarterectomy and CAB under a single anesthetic. Twenty-two patients (42%) had unstable angina and 23 (44%) had previous neurologic symptoms. There were(More)
At the conclusion of standard carotid endarterectomy in 50 consecutive patients, we examined flow in the external carotid artery using a continuous-wave Doppler probe. In two patients (4 percent), flow was absent in the distal external carotid artery. In both patients, opening the external carotid artery through a separate incision revealed an obstructing(More)
