September 1999 7 medicamundi Digital electronics is certainly a technology that has had an enormous impact on our modern way of life. This is demonstrated every day in many instruments that we use. For instance, it is obviously reflected in what gives us dependable and accurate time measurement (digital clocks), undistorted music (compact disc), control of car engine power (electronic fuel inje...

Abstract Personal access communications system (PACS) is a 2 GHz band personal communications services (PCS) standard that supports 32 kbps wireless access services for fixed and mobile subscribers. This paper presents a physical layer architecture, and evaluates the performance, of a multicarrier PACS (MPACS) system based on a combination of orthogonal frequency division multiplexing (OFDM) an...

We report the performance of Wilson and Domainwall Kernels on a new Intel Xeon Phi Knights Landing based machine named Oakforest-PACS, which is co-hosted by University of Tokyo and Tsukuba University and is currently fastest in Japan. This machine uses Intel Omni-Path for the internode network. We compare performance with several types of implementation including that makes use of the Grid libr...

A PACS contains different types of data and databases, which have traditionally been stored in different formats. They include image data, demographic data, and DICOM data, as well as functional data such as image enhancement or manipulation performed by the radiologist. Image data may be treated as objects, while patient data may be stored as text. These variables can become major obstacles wh...
