Honey, I Shrunk the Beowulf!

چکیده
In this paper, we present a novel twist on the Beowulf cluster — the Bladed Beowulf. Designed by RLX Technologies and integrated and configured at Los Alamos National Laboratory, our Bladed Beowulf consists of compute nodes made from commodity off-the-shelf parts mounted on motherboard blades measuring 14.7 00 4.7 0.58. Each motherboard blade (node) contains a 633-MHz Transmeta TM5600TMCPU, 256-MB memory, 10-GB hard disk, and three 100-Mb/s Fast Ethernet network interfaces. Using a chassis provided by RLX, twenty-four such nodes mount side-by-side in a vertical orientation to fit in a rackmountable 3U space, i.e., 19 00 in width and 5.25 in height. A Bladed Beowulf can reduce the total cost of ownership (TCO) of a traditional Beowulf by a factor of three while providing Beowulf-like performance. Accordingly, rather than use the traditional definition of price-performance ratio where price is the cost of acquisition, we introduce a new metric called ToPPeR: Total Price-Performance Ratio, where total price encompasses TCO. We also propose two related (but more concrete) metrics: performance-space ratio and performance-power ratio.

Honey, I shrunk the genome: genome reduction in the leprosy bacillus
The leprosy bacillus is famed for being the first microorganism definitively shown to be associated with human disease. It evades the host's immune response by invading and propagating inside the vacuoles of macrophages called phagosomes. From there, it infects the Schwann cells of the peripheral nervous system, where it disrupts myelin production, thus leading to the characteristic features of...
متن کاملHoney, I Shrunk the Sample Covariance Matrix
The central message of this paper is that nobody should be using the sample covariance matrix for the purpose of portfolio optimization. It contains estimation error of the kind most likely to perturb a mean-variance optimizer. In its place, we suggest using the matrix obtained from the sample covariance matrix through a transformation called shrinkage. This tends to pull the most extreme coeff...
متن کاملProtective effect of natural honey applied during ischemia and reperfusion on infarct size in ischemic heartheart
Introduction: In the current study, protective effect of natural honey applied during ischemia/reperfusion (I/R) was studied on infarct size in ischemic heartheart. Methods: Ischemic hearthearts (n=8 per group) were mounted on a Langendorff apparatus at constant pressure then subjected to 30 min regional ischemia followed by 120 min reperfusion. In control group, the hearts were perfused by ...

A significant development in high-performance computing has occurred in recent years with the proliferation of “Beowulf” clusters [6]. Beowulf clusters are parallel computers assembled from commodity-priced personal computers and networks. The explosive growth of the personal computer marketplace, together with rapid technological advances in the hardware sold there, has driven the price/perfor...
