Newsgroups: comp.parallel From: Mentat Research Group Subject: Mentat 3.0 for Linux Organization: University of Virginia Date: 21 Mar 1997 14:57:39 GMT Message-ID: <5gu7l3$qos@server1.ctc.com> We are please to announce the release of Mentat version 3.0 for x86 class machines running Linux (Kernel version 2.0.18). Briefly, Mentat is an object-oriented parallel processing system developed at the University of Virginia. The programming language, MPL, is a C++ extension. The extensions allow the user to specify those classes that are sufficiently computationally complex to warrant parallel execution. Instances of those classes are treated differently by the compiler. Each instance has an associated thread of control and a unique address space. Member function execution is performed asynchronously. Object scheduling, argument marshalling, communication, and synchronization are managed by the compiler and run-time system. Mentat is a mature system. It has been in use at a number of institutions world-wide for several years. Complete applications ranging from protein sequence comparison, to image processing, target recognition, automatic test pattern generation, database managers, to dense and sparse linear system solvers have been written using Mentat.

This will be fixed in a future release. New version of the mplfront compiler - MPL Language Changes - Compiler enhancements - Bug Fixes Enhanced Scheduling for regular Mentat objects Fault-Tolerance for regular Mentat objects Enhanced Debugging options for Mentat objects New GUI face-lift for thermo, mad_view, and mentatview. Mentatview has been completely rewritten and enhanced. GNU g++ version 2.7.2 support for all platforms. PLEASE NOTE THAT OTHER VERSIONS OF G++ MAY NOT WORK. Miscellaneous bug fixes & enhancements. PLEASE NOTE THAT THIS VERSION OF MENTAT REQUIRES THAT ALL MENTAT OBJECTS FROM PREVIOUS VERSIONS BE RECOMPILED. ALSO NOTE THAT BECAUSE OF THE CHANGES IN THE MENTAT PROGRAMMING LANGUAGE, SOURCE CODE MODIFICATIONS WILL BE NECESSARY. -- Articles to parallel@ctc.com (Administrative: bigrigg@ctc.com) Archive: http://www.hensa.ac.uk/parallel/internet/usenet/comp.parallel
