------- Forwarded Message Date: Fri, 19 Aug 1994 13:30:42 -0400 (EDT) From: Ronald G Minnich <rminnich(a)descartes.super.org> Subject: Re: SSS attachment - is that Splash II? The WSJ article on the Cray-3 deal involves a chip/system designed here called TeraSys. Maya [Minnich djf] has a forthcoming article in IEEE Computer about it. The basic idea is to embed bit-serial processors in the sram chips, one processor per bit in the memory row register. It's a simple processor with an ALU and three registers. The memory "words" can now be thought of as running vertically up the columns, rather than horizontally along the rows. Every time you fetch a row, you are in fact fetching 64 bits from 64 different words to be operated on in the ALUs.This gives you roughly a 100-fold increase in memory bandwidth, since you no longer mux the data down from 64 bits to 1 or 4 bits to bring it off-chip. The key contribution of the Cray (this idea due to Ken Iobst of SRC, who also was the architect of the chips) came from Ken's realization that the Cray vector scatter/gather hardware could push the bits around BETWEEN the chips as fast as the hardware networks on, e.g., the CM-2. Thus the Cray-3, a vector supercomputer, can function as a very high-performance SIMD system as well. You don't need to build the additional network found on so many SIMD machines, e.g. maspar or cm-2. You also can have phases of a program, wherein it runs SIMD for a while, then vector, then SMP mode, etc. The TeraSys processors built here at src cost about $80K each, and for several problems could easily outrun our $6M CM-2. The chips are National Semi SRAMS, with mods done here by Mark Norder and Jennifer Schrader. Ken Iobst is the architect of the chips. The programming environment was basically Maya Gokhale's DBC language, which also runs on Splash-2, the CM-2, and clusters. Cray has reimplemented the chips for the Cray-3. In keeping with the NSAs new plans for SRC, this project was terminated at SRC last January. The systems are gradually being turned off and the cabinets put to other uses. No further work is occurring at SRC in this area. Feel free to forward this article to people who may ask you. There was some good work done by people here. ron rminnich(a)super.org | Error message of the week: (301)-805-7451 or 7312 | NFS server localhost not responding still trying ------- End of Forwarded Message

Economically impractical. Publishing a one-way hash of the text eliminates the role of the trusted time stamper. Alice can simply sign the text herself and then publish the hash right away (in a Usenet newsgroup for example). Trusted time stampers of course are trusted. It means they have reputations for being secure and reliable, and reputation is worth more to them than any possible benifit they can gain from abusing that trust. Of course, this may not work out in reality, but the theory sounds good to me. A way to convince the public that your time stamp is valid without publishing it at the time of the time stamp or absolute trust (on the public's part) on the time stampers is to use a large number of time stamping services. This way, they must all have colluded or been subverted in order to forge your time stamp. Therefore, the time stamp has a high probability of being valid. cc: CYPHERPUNKS MAILING LIST in 0009 on ESKIMO -----BEGIN PGP SIGNATURE----- Version: 2.3a iQCVAgUBLlUSnjl0sXKgdnV5AQFrkwQAopVBwQaFB5YkpKPkWfsOwA2xsTp4vNmZ SIfJDbhdEM2T2xRbGi9QEofADeIoISgVtN6hkhgeQnk5eyvI3EFL8K+ocqc5rYAQ mQAEsTY9sEvZ2CzQr8grayuvhSnnWRmQKSTsfELctWzZciqlDpHbhI++7G1c9hI+ 1zFEE/2HPoQ= =VtUy -----END PGP SIGNATURE----- PGP Public Key available

Some facts on the Cray-3 deal
by pcw＠access.digex.net 17 Dec '03

17 Dec '03

<FORWARDS deleted....> I should note that the processors on this machine sound strikingly like the Coherent Memory Chips that I turned into DES crackers. Also, the SRC's observation that the routing network of the SIMD machines is expensive is an old one at Coherent. Their memory chips were only connected with a one dimensional network and Chuck Stormon felt that this was the only connection arrangement that scaled. This is one of the sad limitations of packaging. In SIMD machines with multiple processors per chip it is often impossible to quadruple the number of processors per chip when a new fabrication process emerges. There just aren't enough pins available. It turns out that the 12 dimensional routing network of the Connection Machine was really overkill. A three dimensional one was nice on some problems, but you paid the price in performance. I'm not surprised that the Terasys could really run rings around the CM-2 for some problems that didn't need the bandwidth. It does sound interesting if the scatter/gather hardware can do a good job with the routing. (It is interesting that this announcement came on the same timeframe as the obituaries for Thinking Machine. They all said stuff like "These guys were brilliant and the machine was great...but the market didn't see their brilliance." It would be funny if the old Cray design proved to be just as versatile.) All that being said, I don't really think that this machine will be anywhere near as powerful as the one I described. The 512,000 processors would probably take about 300-1000 days to do a brute force DES search. The main advantage is that the processors have 64 bits available in memory, not 42. That's just enough to store a complete DES (or SKIPJACK!!!) block in place. There is no need to use the communication hardware to go back and forth. I'll do a more complete calculation later. I don't know whether they'll be able to add more SIMD processors with time. 512k words of memory seems pretty small even when there are 8 bytes to a word. -Peter Wayner >Date: Fri, 19 Aug 1994 13:30:42 -0400 (EDT) >From: Ronald G Minnich <rminnich(a)descartes.super.org> >Subject: Re: SSS attachment - is that Splash II? >To: jms <jms(a)central.cis.upenn.edu> >Cc: f-troup(a)AURORA.CIS.UPENN.EDU > >The WSJ article on the Cray-3 deal involves a chip/system designed here >called TeraSys.

| From: HPCwire article-server <more(a)hpcwire.ans.net> | Message-Id: <199408191753.AA16894(a)hpcwire.ans.net> | To: adam(a)bwh.harvard.edu | Subject: 4493 CRAY COMPUTER AWARDED CRAY-3/SSS DEVELOPMENT CONTRACT August 17 | | CRAY COMPUTER AWARDED CRAY-3/SSS DEVELOPMENT CONTRACT August 17 | IN THE NEWS by Carol Cramer, Managing Editor HPCwire | ============================================================================= | | Colorado Springs, Colo. -- A joint development contract between Cray | Computer Corporation and the National Security Agency (NSA), valued at up | to $9.2 million, is slated to produce a CRAY-3/Super Scalable System (SSS). | | Under the terms of the contract, Cray Computer Corporation will be paid up | to $4.2 million for development costs, and the Government will provide | approximately $400 thousand in software consulting services. The company is | responsible for the balance of the development costs. In addition, it will | have rights to use certain Government technologies. | | The CRAY-3/SSS will be a hybrid high performance system that will offer | vector parallel processing, scalable parallel processing and the | combination of both. | | "NSA selected Cray Computer Corp. to develop the CRAY-3/Super Scalable | System because of its advanced technologies and the CRAY-3 architecture," | stated George Cotter, chief scientist for the NSA. "This is an important | initiative of the Federal High Performance Computing and Communications | (HPCC) program." | | Chuck Breckenridge, executive vice president for Cray Computer | Corporation, noted, "The CRAY-3/SSS will provide unparalleled performance | for many promising applications. We are pleased to participate in this | transfer of government technology and we are eager to help potential | customers explore and develop appropriate applications." | | Based on a September 1993 feasibility study, this development recommends a | hybrid supercomputer composed of a CRAY-3 and a large number of Processor-In- | Memory (PIM) chips, developed by the Supercomputing Research Center (SRC: | Institute for Defense Analyses). The SRC will provide significant technical | assistance in both the software and hardware aspects of the system. | | The Government's technology transfer program is intended to maintain the | country's technology leadership position by providing a cost sharing | arrangement for development and commercialization of advanced Government | technologies. | | The high performance system will consist of a dual processor 256 million | word CRAY-3 and a 512,000 processor 128 million byte Single Instruction- | Multiple Data (SIMD) array. This CRAY-3/Super Scalable System will provide | high-performance vector parallel processing, scalable parallel processing | and the combination of both in a hybrid mode featuring extremely high | bandwidth between the PIM processor array and the CRAY-3. SIMD arrays of 1 | million processors are expected to be available using the current version | of the PIM chip once this development project is completed. | | The scalable array will connect to the CRAY-3 memory interface and will | be addressable as standard memory to facilitate use of the SIMD array with | minimal delays for data transfer. The PIM chip, containing 64 single bit | processors and 128K bits of memory, was developed by the Supercomputing | Research Center for NSA, and tested on a Sun/SPARC workstation with a | parallel version of the C language. | | The PIM chips will be packaged by Cray utilizing its advanced multiple | chip module (MCM) packaging technology that allows the CRAY-3 to operate | with a record breaking 2.08 nanosecond clock rate. The PIM chips are | manufactured by National Semiconductor Corporation. The CRAY-3/SSS is | expected to be demonstrated in the first quarter of 1995. After this | initial demonstration, interested parties will be invited to try out other | applications. | | The CRAY-3 memory interface bandwidth will allow the application specific | SIMD array to provide dramatic performance improvements over existing | architectures for bit and image processing, pattern recognition, signal | processing, and sophisticated graphics applications. A notable strength of | the SIMD processor array is variable precision floating point for those | frequently occurring applications requiring less (and sometimes more) than | the standard 64 bit IEEE floating point arithmetic. A substantial | applications base is available for the CRAY-3, and Cray Computer Corporation | is committed to working closely with customers to develop traditional high | performance vector and scalable applications. | | For suitable applications, the SIMD processor array option offers up to | 32 Trillion Bit Operations per Second and provides price/performance | unavailable today on any other high performance platform. The CRAY-3 system | with the SSS option will be offered as an application specific product and | will be well positioned in the evolving supercomputer marketplace. | | Seymour Cray stated, "The CRAY-3/SSS development project leverages the | company's existing technologies and accelerates our program to develop | parallel architectures and software to reach the TeraFLOPS performance | level. I see a strong SIMD architectural component as crucial to a complete | parallel supercomputer capability." | | ***************************************************************************** | Copyright 1994 HPCwire. | To receive the weekly HPCwire at no charge, send e-mail without text to | "trial(a)hpcwire.ans.net". |

Re: In Search of Genuine DigiCash

A few days ago I asked: > Can a case be made that anonymous digicash is less risky > (to a bank) than NON-anonymous digicash? There were no takers. Therefore, I'll ask different questions: Would a Chaum-style anonymous digital cash service be more profitable to a bank than a NON-anonymous digital cash service? Are the costs involved in offering and supporting anonymous digital cash more, or less, than the costs associated with NON-anonymous digital cash? In other words, why might a bank chose to offer/support anonymous digital cash over NON-anonymous digital cash? If a "bank-centric" case for anonymous digital case over NON-anonymous digital cash can't be made, then there's little chance we'll see anonymous digital cash any time soon. Jim_Miller(a)suite.com
