FD-buffer: a buffer manager for databases on flash disks.

are client-server based, which is feasible for relatively slow role-playing games. Those have modest bandwidth and latency requirements and are paid for by their customers. For MMOGs with higher realtime requirements and/or a smaller number of customers willing to pay, peer-to-peer networking seems to be a

their cache upon reconnection, to allow stateless servers, and to minimize the bandwidth requirement. The general approach is 1) to use asynchronous invalidation messages and 2) to buffer invalidation messages from servers at the MH's Home Location Cache (HLC) while the MH is disconnected from

this asymmetry in FD-Buffer. Specifically, we use the average I/O cost per page access as op-posed to the traditional miss rate as the performance metric for a buffer. We develop a new replacement policy in which we sepa-rate clean and dirty pages into two pools. The size ratio of the two pools is automatically

ABSTRACT. We analyze a reform of insurance companies’ capital requirements for mortgage-backed securities. First, credit ratings were replaced as inputs to capital regulation. Second, the redesigned system ensures capital buffers sufficient to withstand expected losses, but insufficient to protect

In this paper, we investigate the buffer requirement to support a set of continuous media playbacks and develop an algorithm which dynamically changes the service mode of the playback to minimize the total buffer requirement. A certain amount of memory buffer is required in continuous media

that passing the negative test cases is worth at least as much as passing the positive test cases. Intuitively, this weighting rewards the search for moving toward a possible repair. Programs that do not compile are assigned fitness zero. Minimizing the repair Because the GP may introduce irrelevant changes

Using the OpenSSD Jasmine board, we develop a prototype of FlashTier’s Solid State Cache (SSC) and of the Nameless Write SSD. While the flash-translation layer changes were straightforward, we discovered un
