Memory traffic flow from CPU memory 

 ports througfi a memory arbitration net- 

 work, and back to CPU input ports. 

 Eacti colored rectangle represents one 

 ptiysical queue organized in groups. 

 The colors represent the queue state: 

 for example an empty queue is white 

 and a full queue is red. The animation 

 of this display shows memory message 

 traffic through the memory network. Its 

 purpose is to point out possible clogs 

 and busy spots within the network. 



sities. NSA's National Cryptologic School and the SRC 

 develop courses suitable for users of high performance 

 computing environments. 



Management 



The overall coordination of NSA's HPCC activities 

 resides in the office of the NSA Chief Scientist, who 

 reports to the Director of NSA. Responsibilities for exe- 

 cution of major elements of the plan lie with the 

 Technology and Systems Directorate and the 

 Information Systems Security Directorate. NSA spon- 

 sors the SRC in exploring massively parallel computer 

 architectures and in developing algorithms and systems 

 software for parallel and distributed systems. The SRC 

 heavily supports NSA's HPCC activities directly and by 

 collaborative efforts with other HPCC participants, espe- 

 cially industry and academia. 



FY 1994 Plans 



HPCS 



Extend existing high performance system simulators and 

 testbeds at NSA and the SRC. 



Develop mass archival storage 



10'' to 10'*^ bits. 



Define techniques for the interoperability of distributed 

 operating systems spanning large sets of heterogeneous 

 computer assets, including supercomputers. 



Integrate major new vector/scalar massively parallel pro- 

 cessor as a research system. 



Demonstrate a terabit/second (lO'^-bit-operations-per- 

 second) deskside SIMD system. 



Continue technical cooperation with major vector/mas- 

 sively parallel processor developers. 



Investigate, cooperatively with industry, processing-in- 

 memory (PIM) technology in established systems archi- 

 tectures.
