Anybody who has prior experience or references on this matter please forward them to me at zenios@wharton.upenn.edu A more extensive message with specific questions follows: I am working with a couple of graduate students to implement some parallel optimization algorithms accross our network. None of us has any experience with NCS. Before I get them seriously involved in this project I would like to get some feedback on the following: (1) Is NCS fully developed and supported (Not what the manuals say; what do you as an experienced user think?) (2) Can it be used for implementation of a Fortran/C program in parallel? (3) How efficient is communication accross the network? How severly would it interfere with the speedup of the parallel algorithm. (4) You have any --- prefereably published --- references on the use of NCS for distributed computing (lienar algebra, simulation, optimization, etc)? (5) Is there a good person at Apollo we could contact? Thanks for any info you could give. You can also reach me at (215) 898-6727 Stavros A.
