Online Resources

A list of published and/or online papers related to Elepar technology can be found here.
An early form of our Cooperative Data Sharing (CDS) interface for portable low-level parallel and distributed processing (including source, object, man pages, and web description) is available as open source at cds-bcr.sourceforge.net.
If you have filled out our survey, you are registered, and can use the returned password to access more information--e.g. text and slides to some of the papers cited above, a Principles of Operation paper for CDS, some potential extensions for CDS, and a tutorial for an early version of Software Cabling.

Consulting and/or Contracting

Elepar offers a variety of consulting and contract programming arrangements. Contract programming is offered primarily for (open source) CDS fixes, extensions, and upgrades.

Presentations and Seminars

Presentations are designed as 50-minute technology introductions plus 10-to-20 minute question periods. Base prices are fixed (i.e. independent of number of attendees), but additional expenses (travel, lodging, lost time) may vary depending on circumstance.

Seminars (unless otherwise noted below) are designed as half-day sessions which include indepth info plus some materials and personalized attention. Cost is per person. Must have at least 10 attendees, and any transportation and lodging costs will be added if fewer than 20 (to be optionally paid by hosting organization, or divided among attendees).

Choose from the list below, or let us customize something just for your organization. Please contact us for prices.

List of Presentations and Seminars

High-level Overview of Elepar Technologies

[Presentation HLOE] Covers the history and aims of CDS (Cooperative Data Sharing), SC (Software Cabling), and PICA (People, Instruments, Computers, and Archives)

Issues in Grid and Peer-to-Peer Computing

[Presentation IGPC] Covers issues and history behind grid computing and peer-to-peer computing

Cooperative Data Sharing (CDS) User Interface and Use

[Presentation CDSU] Covers the basics behind the CDS API, including the primitive communication operations, how they are built into more complex operations, and how they address both shared memory and message style communication in all environments.

[Seminar CDSU] An indepth explanation of each category of the CDS user interface, how those categories relate to one another and to other programming techniques such as MPI or shared memory, and how to optimize CDS programs for maximum portable performance. Also explores potential extensions to the interface.

Cooperative Data Sharing (CDS) Internals

[Seminar CDSI] Covers the internals of the current (open source) implementation of CDS (BCR flavor), including data structures, use of shared memory, and reliable communication over UDP/IP. Suggests potential improvements, and approaches to implement proposed extensions.

Software Cabling (SC)

[Presentation SC] Covers the rationale, syntax and semantics of the primary constructs of SC.

Please contact us regarding seminars covering SC principles, usage, relationship to other component and modeling languages.

Theory behind the F-Nets portable parallel computational model

[Presentation] Covers the F-Nets computational model in fairly simple terms, provides a high-level description of the syntax and both axiomatic and operational semantics, as well as intuition into how it compares to other models.

[Seminar] Formal description of F-Nets computational model, along with complete description and explanation of mathematical axiomatic semantics. Specific comparison with other models such as Turing Machines, cellular automata, Unity, Petri Nets, etc. Proof of certain properties (using the formal semantics) such as static analysis for non-determinism and logging required for replay.

PICA (People, Instruments, Computers, and Archives)

[Presentation] Covers the rationale and constructs of PICA.
