GLOBAL foilset NII Technologies from WebTop Productivity to Computing -- Industrial Uses of HPCC

Given by Geoffrey C. Fox at Minnesota Presentations at Cray Research and University on 13-14 November 95. Foils prepared 10 November 1995
Abstract * Foil Index for this file See also color IMAGE

We describe an analysis of possible industrial uses of HPCC indicating that "NII" (Multimedia servers) applications will dominate.
Looking at applications such as education and manufacturing show important opportunities for linking database and simulations.
This suggests that there are several advantages in building HPCC services such as parallel compilers and messaging systems in terms of Web Technologies.
This brings tremendous leverage of existing and emerging WebTop productivity tools and allows an excellent parallel software engineering environment.
We comment on theimpact of computational science education and our program at Syracuse which now has two tracks -- simulation and Information based.

Firstly we can use this technology to implement HPCC on a broad technology base
  • This implies that machines such as Cray T3D/E would be run with a Web Server on every node ...
Secondly we can use technology to implement Virtual University to teach internally and across the Globe
Thirdly we can teach our students about these concepts
  • new curricula for computational science
  • large demand (and salaries) for such students!

Natural Strategy is for Web Servers in U.S.A.. to deliver educational material via FLAG to Africa and Far East
This would set up hierarchically as:
  • U.S.A.. to first offramps: Coastal Countries (in Africa)
  • Coastal Countries distribute information in cascade fashion to rest of continent
  • Download bulk educational material ONCE (standard caching scenario)
  • Use FLAG Interactively for exploration and for student-teacher Interaction

WebWork pilot project is a collaboration between NPAC, Boston University and Cooperative Systems Corporation, MA. It will prototype a candidate VSL, WWVM, Java based user interfaces, and port selected Grand/National Challenge applications to this platform.
The project will use NPAC WebTools to bootstrap the software process and will prototype WWVM in terms of current Web technologies (Screen 1)
Technically, early WWVM will include existent Web Servers with add-on CGI (Perl) scripts that build server-to-server communication and offer document database management, and module publication and linkage/instantiation support.
This base model will be further extended and refined by using and driving evolving Web technologies. For example, the disk-based model in Screen1a will likely evolve towards memory-mapped model based on multi-threaded interpreted compute-servers (Screen 1b)

Full HTML Index
Illustrates implementation of WebWork message passing in terms of
  • a): current Web technologies (HTTP/CGI), and
  • b) next generation multithreaded compute-servers
This diagram illustrates point-to-point communication between Web servers, used to implement a webflow channel between compute-web modules. Two extreme implementation modes are described: a) based on today's Web server technology, and b) based on thread memory mapped high performance implementation, expected in future Web compute-servers. Subsequent steps, represented by a sequence of labelled lines in the figure, are described below in both implementation modes.
a) Today's Web server mode: (1) -- M1 locks O1 on S1 disk. (2) -- M1 sends POST HTTP message to S2 with M2 URL in the header sector and with O1 URL in the body sector. (3) -- S2 activates M2 via CGI and passes O1 URL as a command-line argument. (4) -- M2 sends GET method to S1 with O1 URL in the header. (5) -- S1 fetches O1 from its document tree. (6) -- S1 sends the content of O1 to M2 which completes the GET exchange. (7) -- M2 saves O1 by overwriting current I2 on the S2 disk. If I2 is locked, M2 waits (blocks). (8) -- After O1 is saved on the S2 disk, M2 returns 'end-of-transfer' acknowledgment to M1 which completes the POST exchange. (9) -- M1 unlocks O1 and exists.
b) Compute-server (future Web server) mode: (1) - M1 locks its memory object O1. (2) - M1 checks if socket connection to M2 is in M1 connection table. If yes, go to (5) below. Otherwise, M1 connects to S2 and sends M2 creation script. (3) - S2 spawns M2 and acknowledges. (4) - M1 receives acknowledge message and saves new socket in connection table. (5) - M1 gets O1 handle. (6) - M1 writes O1 to M2 using socket lib calls. (7) - M2 reads O1 using socket lib calls. If I2 is free, O1 buffer is copied directly to I2 buffer. If I2 is locked, M2 creates O1 clone and blocks. (8) - M2 sends acknowledge to M1. (9) - M1 unlocks O1 and blocks.

More generally, this Middleware Layer 2 will be rather complex and populated by a spectrum of proprietary (e.g. Telescript, ScriptX, CORBA) and public (e.g. Perl, Tcl, Harvest, Java, VRML) scripted languages, brokers, agents, wrappers, mediators etc. see Screens
In WebWork, we refer collectively by WebScript to the whole ensable of these models.
At the current stage, it isn't clear if WebScript as a common intermediate language is a practical concept. An alternative is to live in the multi-language Web medium and emply interoperability agents to translate between various protocols.
Practical initial implementation platfrom for this dual approch is provided in WebWork by an integrated collection of WebTools CASE tools based HySource Worlds for various languages.

We need to use compilers on tightly coupled systems such as MPP's (shared and distributed memory)
But for metacomputing, the hardware intrinsically has latencies that suggests increased flexibility of interpreters is more appropriate
  • This implies a hybrid compiler-interpreter environment
Maybe frontends should be built with interpreters such as object-oriented PERL5 so easier to link with Web.
Note that interpreted environment will have best software engineering support and so suggestion is -- taking SP2 as example:
  • debug on SP2 set up with compute-enhanced Web Server on each node with say MPI running on top of HTTP message passing protocol
  • execute debugged code on conventional SP2 with high performance compiled environment

This implies that we should allow hybrid model not just for task (interpreted) versus data parallelism(compiled)
  • Rather should support full data parallelism in interpreter
  • NPAC demonstrated a protype HPF interprter at SC93
Current Web Interpreters include Java TCL and PERL(5) which are optimized for different application domains
  • For instance PERL is optimized for documents/files and Java for browsers
This leads to WebScript Concept of interoperable interpreters optimized for different domains
  • WebHPL (High Performance Language) is then script optimized for computing which links compiled HPL modules on tightly coupled MPP's
  • This naturally suggests that we can link domain specific systems (e.g. partial differential equation toolkit) to HPF future and WebHPL

Java is a C++ subset which interestingly does not have pointers as these are unsafe in necessary secure metacomputing environment.
Thus Java has removed the part of C++ which is hardest to parallelize
Java may not "survive" but if it doesnt something better will! Thus it makes sense to study and experiment with it
Natural first step is to use Java to build the interpreted "shell" which we called HPFCL for HPF coordination Language.
  • This is task parallel script linking HPF modules
Java is partially compiled as you take basic Java high-level code and compile down to a universal Java machine language. This is very similar to concepts in ANDF (Architecture Neutral Distribution Format) but with a different goal

VRML -- Virtual Reality Model Language -- is an object oriented database built as a subset of the SGI Inventor System
VRML can be considered as another script optimized for graphics but not many interesting processing (compute) capabilities are in current standard
VRML can be considered as an example of a universal data structure allowing exchange of 3D objects over the Web.
  • These objects could either be tanks in a videogame or parts of an aircraft used in large scale simulation
Thus useful to consider data parallel VRML and building CC++ or HPF(Fortran90) modules to support VRML
HPCC community should join with the Web to ensure that standards such as VRML can be implemented efficiently either in parallel (maybe a niche) but also in a distributed network (similar issues where HPCC can contribute and clearly very important)
