Elmaghraby) Organization: University of Louisville Subject: Re: SIMULATION DIGEST V7 N7 To: SIMULATION@UFLORIDA.CIS.UFL.EDU X-Original-To: SIMULATION@UFLORIDA.CIS.UFL.EDU In Reply to: (1) Multi-Processing Computer System Modeling (2) Architecture Modelling I know that NETWORK II.5 by CACI has very good potential for these simulation. I have used it both on PC and Vax. Furthermore an accompanying book by: Chueng, Dimitriadis, and Karplus titled " Introduction to Simulation Using Network II.5" has several detailed examples such as a multiprocessor computer, an a time shared computer system in addition to other computer network examples. The software basically thinks in terms of Processing Elements with user defined instructions, storage devices, and obviously Data Transfer devices. It allows you to set an elaborate definition of software and system characteristics. Network is written in Simscript and has some simple animation capabilities on the PC version. Adel S.

The major simulation languages such as SIMSCRIPT, SLAM II and GPSS can be used for architecture simulation. If you want to work in C, you might consider CSIM (from Herb Schwetman at MCC) or SMPL (from M. H. MacDougall): he has a recent MIT Press book on Simulating Computer Systems. Both of these two languages lean toward the simulation of computer systems specifically and they both come complete with C source code. CSIM is process oriented and SMPL is event oriented. As far as languages that are tied specifically toward computer network simulation, you can check out Columbia's network testbed simulation system (called NEST). NEST was discussed in an earlier digest issue. -paul +------------------------------------------------------------------------+ | Prof. Paul A. Fishwick....

In our research project, we have to check whether a set of numbers are uniformly distributed within a certain range. For instance, if we have n m-bit numbers, how do I tell if the n numbers are uniformly distributed (or very close to) in the range of 0 to 2**(m-1)? I saw a short article in IEEE Spectrum (Aug. 1988 issue, p. 13) mentioning some software developed by Clifford A. Pickover at IBM that can plot a graph showing the randomness of Gaussian noise. Does anyone have any further information about it? Any pointer to any literature or existing software/algorithms? - Dik Lee Dept.
