Deep Computing

Vol. 48, No. 2, 2004

Order No. G322-0239
Deep computing—high-performance computing applied to problems that require significant computing resources in order to facilitate relatively complex decision-making in fields ranging from business to the sciences—is becoming increasingly important. Most of the papers in this issue pertain to relevant, new algorithmic approaches; simulation of astrophysical and magnetic phenomena; data handling and the network infrastructure needed to support large data movement; and related aspects of grid computing. A previous double issue of this Journal [Vol. 45, No. 3/4 (2001)] and a companion issue of the IBM Systems Journal [Vol. 40, No. 2 (2001)] focused on deep computing for the life sciences.
