Community Research and Development Information Service - CORDIS


A Client-Server-Monitor computational environment is presented. This environment is based on a data management system which provides tools for the logical and physical organization of data. Calculations are performed by Client programs on a distributed memory system under the control of the Server. Data are handled by means of a Database Server module connected to the Server. The Monitor module, which is based on the XGrafix library, offers capabilities for on-line interactive monitoring of running applications. The MEM-COM Database is used as the data management system and communication within the Client-Server-Monitor environment is done using a parallel virtual machine (PVM). Performance measurements are presented as well as experiences with a particle-in-cell (PIC) simulation running on a Cray T3D.
