- Welcome to the High Performance Fortran Forum!
-
-
- WHAT IS HPFF?
- =============
-
- Since its introduction over three decades ago, Fortran has been the
- language of choice for scientific programming for sequential
- computers. Exploiting the full capability of modern architectures,
- however, increasingly requires more information than ordinary Fortran
- 77 or Fortran 90 programs provide. This information applies to such
- areas as
-
- 1. Opportunities for parallel execution
- 2. Type of available parallelism - MIMD, SIMD, or some combination
- 3. Allocation of data among individual processor memories
- 4. Placement of data within a single processor
-
- The High Performance Fortran Forum is a coalition of industrial and
- academic groups working to identify the basic issues and suggest a set
- of standard extensions to Fortran to provide the necessary
- information. To date, the group includes most vendors currently
- delivering parallel machines, government labs, and many university
- research groups. Our intent is to develop extensions to Fortran which
- provide support for high performance programming on a wide variety of
- machines, including massively parallel SIMD and MIMD systems and
- vector processors. Some of the topics considered will be
-
- 1. Data distribution and alignment
- 2. Explicit parallelism, particularly for data-parallel problems
- 3. Computation distribution
- 4. I/O support
-
- The result of this project will be an industry-wide standard
- language portable from workstations to massively parallel
- supercomputers. Furthermore, the language will be able to express the
- algorithms needed to achieve high performance on specific
- architectures in this range.
-
- Anybody with an interest in using Fortran on modern architectures is
- welcome to participate in HPFF. In particular, we welcome comments
- from
-
- 1. Fortran users writing new applications for modern architectures
- 2. Fortran users porting programs to new architectures
- 3. Fortran compiler and programming environment implementors
- 4. Researchers interested in extending Fortran
-
- To allow wide participation, all HPFF materials will be available
- electronically, and we welcome electronic comments (send mail to
- chk@rice.edu).
-
-
- WHERE CAN I GET MORE INFORMATION ON HPFF?
-
- Electronic copies of HPFF draft proposals, minutes of the working
- group meetings, and other related documents are available by anonymous
- FTP from titan.cs.rice.edu. To get these, follow the following script
- (things you type are underscored with ^):
-
- % ftp titan.cs.rice.edu

-
- HOW CAN I PARTICIPATE IN HPFF?
-
- One way to participate is to attend the HPFF working group meetings.
- To try to ensure productive meetings, we ask that working group
- attendees make a commitment to attend at least half of the meetings.
- Also, at most 2 participants from each company/school/laboratory are
- allowed. Contact Ann Redelfs (redelfs@rice.edu) for more information
- about the working group.
-
- An easier way to participate is to join one or more of the HPFF
- mailing lists. The possible lists are
- hpff Main HPFF list (meeting minutes,
- pointers to language drafts,
- miscellaneous announcements)
- hpff-f90 Discussion group for the relationship
- between HPF and Fortran 90
- hpff-distribute Discussion group for models of data
- and work distribution
- hpff-subroutines Discussion group for subroutine
- interfaces and automatic redistribution
- hpff-forall Discussion group for FORALL
- statements, local subroutines, and
- explicit process control
- hpff-io Discussion of parallel I/O and other
- miscellaneous matters
- hpff-intrinsics Discussion of new intrinsic functions
- useful for parallel programming
- All mailing lists are kept at cs.rice.edu.
-
- To add your mail address to one of the HPFF mailing lists, mail a
- message to hpff-request@cs.rice.edu with a subject line containing the
- word "add" and the name of the list. This will add the E-mail address
- of the message originator to the requested mailing list (if no list
- name is given, the address is added to "hpff"). For example, to
- receive the Fortran 90 discussions, send a message with "Subject: add
- hpff-f90".
