Stochastic Conditional Duration Models with Leverage Effect for Financial Transaction DataFeng, Dingan, Jiang, George J. and Song, Peter X.K., "Stochastic Conditional Duration Models with Leverage Effect for Financial Transaction Data" . Journal of Financial Econometrics, Vol. 2, No. 3, pp. 390-421, 2004 Abstract:
Facts on IBM SoftwareMany businesses run multiple server farms but wish to consolidate them into a single smaller server farm. This is because most server farms are underutilizied or over provisioned. The boxes are typically running at 10% load which is quite costly and is not flexible. For example, one server farm goes hot and maxes out while the farm in the next room is still basically idle at 10%. XD allows administrator to define a single cluster (a node group) then monitor the workload and dynamically decide which boxes in the node group should host which application in order to meet these goals. If application A has a current response time of 1.5 seconds, XD will move resources away from applications B and C to increase the power dedicated to A and decrease its response time. XD can also predict that A will likely exceed its response time in 10 minutes based on a trend and react in anticipation of the event. This greatly simplifies the life of an administrator and allows the machines to be more efficiently used than a conventional multiple, independent farm of farms approach. XD also offers options to generate various email alerts when conditions are exceeded, it can restart servers when they appear to have a memory leak or after X requests. Lotus Software (called Lotus Development Corporation before its acquisition by IBM) is an American software company with its headquarters in Cambridge, Massachusetts. Lotus was founded in 1982 by partners Mitch Kapor and Jonathan Sachs. Lotus' first product was presentation software for the Apple II known as Lotus Executive Briefing System, but the company is more broadly known for its groundbreaking Lotus 1-2-3 spreadsheet application released in January 1983. With Rational, IBM now will provide a complete software development environment for companies that want to integrate their business processes and software infrastructure across their companies and with suppliers, customers and employees. This requires the integration of data management, systems management, collaboration, transaction and business process integration middleware and software development. The acquisition of Rational will strengthen IBM’s leadership in each of these segments, including software development, and reinforces IBM's commitment to open industry standards. The acquisition is an important element of IBM's e-business on demand strategy.
