We are seeking software developers interested in participating in a
functional and usability study of a new software package, PCthreads(tm).
PCthreads is an instrumented, multithread facility for MS-DOS(tm)
systems based on the POSIX 1003.4a API, "Threads Extension for Portable
Operating Systems". In the UNIX world this API is often referred to as
the "pthreads" API. The PCthreads package is designed for programmers
whose software is required to be portable between both UNIX and MS-DOS
environments. Hence, PCthreads strict adherence to the POSIX standard.
Our goal is to produce a highly functional, yet easy to use, developer's
kit for designers of UNIX and MS-DOS multithreaded software. While the
design of threads packages, like PCthreads, is well understood, how to
program with threads is not. More to the point, tools that help the
grundoon programmer develop sophisticated parallel and/or interrupt driven
asynchronous applications are scarce. The strategy employed in this study
is to provide a reasonably complete, POSIX-based threads package to its
participants, in return for which they will share with us (and
subsequently this newgroup) their functional and usability requirements.
There is no cost for participation but, because of our size and ability to
support this study, we must limit the number of participants. Our
preliminary selection criteria is based on the application area and the
experience of the participants (assuming, of course, there is enough
interest... [:-) ).
We're especially interested in working with developers whose software
could benefit from an asynchronous, or interrupt driven, execution
environment. For example:
o Conformant POSIX 1003.4 API (Realtime) services for MSDOS users
o [Multithreaded] device drivers (especially disk and network).
o Asynchronous communications and/or keyboard I/O services.
o Database servers.
o Distributed Computing services (e.g., RPC-based client-server
applications)
If you are interested in participating please reply privately to this note
letting us know what your area of application interest is. If not
interested in participating, or can not participate, but have a technical
question about the package feel free to send me mail.
We will post the results of the study to this newgroup (e.g., a set of of
functional and usability requirements) upon its completion. In return for
the use of this public newsgroup, and your patience, a non-crippled,
complete implementation of the PCthreads package will be made available
via FreeWare (i.e., send us a disk and a SASE and we'll send you the
software) when the study is complete.
