     I am currently taking an "Advanced Computer Architecture"
course, and am doing a project on the Denelcor HEP (Heterogenous
Element Processor) machine.
     However, I am having problems finding references.  
I would appreciate suggestions as to where I can find any
material relating to the HEP, specifically, for the following:
	
        1) Architectural Description
        2) Pros and Cons of this architecture
        3) Specific Applications
        4) Reasons behind WHY they (Denelcor) chose this architecture.

     The material that I DO have, includes the following :
    
        a) Parallel MIMD Computations: HEP Supercomputer and Its
           Applications
           (note that is book is a collection of papers, and is
            concerned more with parallel algorithms, as they 
            affect the HEP, than it is with describing the
            machine itself)
        b) Computer Architecture & Parallel Processing, by
           Hwang & Briggs, pages 669 to 684.
           (this gives a fair introduction to the HEP)

      However, there are a few references that I am having trouble
locating :
        i) Proceedings of the Workshop of Parallel Processing Using
           the Heterogenous Element Processor, March 20-21, 1985.
       ii) Heterogeneous Element Processor Principles of Operation,
           Publication #9000001, Denelcor, Inc. 1981
           

       Note that I did consider writing to Denelcor directly, but
I understand that they have gone out of business, so it would be
quite difficult to contact them.

       Any suggestions as to where I could find the references, or
any other information would be appreciated.  Please e-mail to the
following address :

(If there is an interest for this information, I will then post
 the references to the net...)
