- Subject: High Performance Fortran - Announcement & Request for Comments
-
- Announcing a new version of the High Performance Fortran Language
- Specification. (Finally!)
-
-
- REQUEST FOR PUBLIC COMMENT ON HIGH PERFORMANCE FORTRAN
-
-
- Invitation:
-
- The High Performance Fortran Forum (HPFF), with participation from over 40
- organizations, has been meeting since January 1992 to discuss and define a
- set of extensions to Fortran called High Performance Fortran (HPF). Our
- goal is to address the problems of writing data parallel programs for
- architectures where the distribution of data impacts performance. While we
- hope that the HPF extensions become widely available, HPFF is not
- sanctioned or supported by any official standards organization. At this
- time, HPFF invites general public review comments on the initial version
- of the language draft.
-
- The HPF language specification, version 1.0 draft, is now available. This
- document contains all the technical features proposed for the language.
- We plan to make minor revisions to correct errors or clarify ambiguities
- in March 1993, at which time we will issue a final draft; however, we
- expect that there will be few (if any) major technical changes from this
- draft.
-
- HPFF invites comments on the technical content of HPF, as well as on the
- editorial presentation in the document. To facilitate incorporation of
- comments into the final document, we ask that comments be sent before
- March 1, 1993.
-
- How to Get the Documents:
-
- Electronic copies of the HPF language specification are available from
- numerous sources.
-
- Anonymous FTP sources: Directory:
- titan.cs.rice.edu public/HPFF/draft
- think.com public/HPFF
- ftp.gmd.de hpf-europe
- theory.tc.cornell.edu pub
- minerva.npac.syr.edu public
-
- Email sources: First line of message:
- netlib@research.att.com send hpf-v10.ps from hpff
- netlib@ornl.gov send hpf-v10.ps from hpf
- softlib@cs.rice.edu send hpf-v10.ps
-
- The following formats are available. Note that not all formats are
- available from all sources.

-
- For more detailed instructions, send email to hpff-info@cs.rice.edu. This
- will return a message with expanded detail about accessing the above
- document sources, as well as other information about HPFF.
-
- We strongly encourage reviewers to obtain an electronic copy of the
- document. However, if electronic access is impossible the draft is also
- available in hard copy form as CRPC Technical Report #92225. This report
- is available for $50 (copying/handling fee) from:

- CITI/CRPC, Box 1892
- Rice University
- Houston, TX 77251
-
- Make checks payable to Rice University. This document will be sent surface
- mail unless additional airmail postage is included in the payment.
-
-
- How to Submit Comments:
-
- HPFF encourages reviewers to submit comments as soon as possible, with a
- deadline of February 15 for consideration. Please do not submit comments
- for any version of the draft earlier than the 0.4 version.
-
- Please send comments by email to hpff-comments@cs.rice.edu. To facilitate
- the processing of comments we request that separate comment messages be
- submitted for each chapter of the document and that the chapter be clearly
- identified in the "Subject:" line of the message. Comments about general
- overall impressions of the HPF document should be labeled as Chapter 1.
- All comments on the language specification become the property of Rice
- University.
-
- If email access is impossible for comment responses, hard copy may be sent
- to

- Version History
- ===============
-
- Version 0.1:
- August 14, 1992
- EXTREMELY preliminary version.
-
- First collection of the proposals active in the High Performance Fortran
- Forum. Established much of the outline for later documents, and
- represented most decisions made through the July HPFF meeting.
-
-
- Version 0.2:
- September 9, 1992
- Version discussed at the September 10-11 HPFF meeting
-
- Changes:
- General cleaning up of version 0.1.
- Inclusion of most new proposals at that time.
-
-
- Version 0.3:
- October 12, 1992
- Version discussed at the October 22-23 HPFF meeting
-
- Changes:
- - Numerous minor and major changes due to discussions at the September
- meeting.
- - Added a section on "Model of Computation".
- - Presented alternate chapters for data distribution with and without
- templates.
- - Added two proposals for ON clauses specifying where computation is to
- be executed.
- - Added distribution inquiry intrinsics.
- - Total rewrite of I/O material, sending most previous material to the
- Journal of Development.
-
-
- Version 0.4:
- November 6, 1992
- Version to be presented at Supercomputing '92
-
- Changes:
- - Numerous minor and major changes due to discussions at the October
- meeting.
- - "Acknowledgements" section now much more accurate.
- - "The HPF Model" (replacing "Model of Computation") substantially
- simplified and improved.
- - "Distribution without Templates" chapter removed.
- - Many proposals not adopted moved to "Journal of Development".
-
-
- Version 1.0:
- January 25, 1993
- Draft final version
-
- Changes:
- - Many changes for clarity or pedagogical reasons.
- - The examples in several sections have been significantly enlarged.
- - INHERIT (for dummy arguments) added to distribution chapter.
- - Pure procedures may now have dummy arguments with explicit
- distributions, if those distributions are inherited from the caller.
- - Changed the names of the new reductions AND, OR, and EOR to IALL,
- IANY, and IPARITY.
- - Clarified the status of the character array language to be not in the
- subset, and as a result, removed the character array intrinsics. Only
- very restricted forms of alignment subscript expressions (of the form
- \(m*i + n\) where \(m\) and \(n\) are integer expressions) are part of
- the subset. [Bibliography] Correctly spelled ``Mehrotra'' and
- ``Gerndt''.
