Subject: Chair of Stat. and CS department at WVU

Applications and nominations are invited for the position of Chairperson
of the Department of Statistics and Computer Science. The position requires a
Ph.D. in Computer Science or an equivalent field, administrative experience,
and research credentials sufficient to justify a tenured position as an
Associate Professor or Professor of Computer Science. The department is
seeking an academic leader who would be a strong advocate for the
undergraduate and graduate degree programs in both Computer Science and
Statistics with special emphasis on the recently established Ph.D. in Computer
Science.

The department was established in 1969 and consists of 15 Computer
Science faculty, 9 Statistics faculty, 6 full-time support staff, and 51
teaching or research funded graduate students. Faculty have joint
appointments with the DARPA funded Concurrent Engineering Research Center, are
involved in a large NASA Independent Verification and Validation project, and
have research projects funded through NSF, DOE, DARPA, USBOM, and Nippon T &
T. Faculty work on several interdisciplinary project areas in engineering,
agriculture, medicine, and materials science. The chairperson must
administer and guide the Computer Science and Statistics programs, must work
synchronously with the Concurrent Engineering Research Center, and must
interface with the Software Valley high technology infrastructure development
initiative.

West Virginia University is a land-grant institution with an enrollment
of 22,500 including 5,000 graduate students. The University ranks in the top
100 universities in the United States in dollars of externally sponsored
research and development projects. Morgantown is a culturally diverse college
community with a population of about 40,000, and is located on the Monongahela
River, 70 miles south of Pittsburgh and 200 miles west of Washington, D.C.

Applicants should provide a vita and the names, addresses, and telephone
numbers of five references. Applications and inquiries should be sent to Dr.
Stanley H. Cohen, Chair of the Search Committee, 201 Woodburn Hall, West
Virginia University, PO BOX 6286, MORGANTOWN WV 26506-6286. Questions and
inquiries can be made by e-mail: scohen@wvnvm.wvnet.edu or FAX: (304) 293-
6858. However, applications and supporting material should be sent by post.
Screening of applicants will begin on March 8, 1993 and will continue until a
successful candidate is chosen.

Subject: Correction to the report on the Twelvth Parallel Circus

My apologies for any errors in the report on the Twelvth Parallel Circus.
Please note the following correction.

> Gong Chen was next with a talk titled ``A Highly Parallel Algorithm
> for Hessenberg Reduction.'' This talk described work done on an Intel
> iPSC/860 to find methods for reducing matrices to Hessenburg form by
> partitioning schemes suited to distributed memory type machines and
> follows work done by Dongarra and van de Geijn.

Youngbae Kim of University of Tennessee was next with a talk titled ``A Highly
Parallel Algorithm for Hessenberg Reduction``. This talk described work which
is in progress currently and will be implemented on the Intel Paragon to find
methods for reducing matrices to Hessenberg form by partitioning schemes suited
to mesh-connected distributed-memory type machines.

Subject: Student Workshop in Supercomputing

Summer Workshop for Undergraduates
High-Performance Scientific Computing
University of Colorado, May 24 - June 4, 1993

This residential workshop is designed for upper division undergraduate
students who are interested in learning about the use of supercomputers,
high-performance workstations, and visualization in scientific
computing. Workshop participants will use a Connection Machine (CM-2),
a Cray Y-MP, DEC 5000 and SGI Indigo workstations, AVS and IDL (scientific
visualization tools) for solving problems in molecular dynamics,
wave motion, and visualization of data.

Participants will reside in Kittredge Residence Halls on the University campus.
Classes and laboratory sessions will be held in the Engineering Center
located nearby. Residence expenses (room and board) will be paid by
a grant from the National Science Foundation. Transportation expenses will
not be covered.

Attendance at the workshop will be limited to sixteen students. Selection
of participants will be based on the following criteria:

Statement of interest. This statement describes
why the applicant is interested in participating in the workshop,
relevant academic experience and interests, and long-range goals.

Letter of recommendation by faculty member. This letter should be
written by a faculty member who has served as the student's
academic advisor or teacher. It should describe the student's
strengths, academic performance, and potential for achievement.

Satisfying the prerequisites. The prerequisites are experience with
the Unix operating system, two semesters of calculus, one semester of
numerical analysis, two semesters of courses in physical or biological
science.


Inquiries and applications should be sent to: Professor Elizabeth Jessup,
Dept. of Computer Science, University of Colorado, Boulder, CO 80309-0430;

Subject: Faculty Workshop in Supercomputing

Summer Workshop for Faculty
High-Performance Scientific Computing
University of Colorado, June 7 - 18, 1993

This residential workshop is designed for college faculty
members interested in teaching scientific computing to
undergraduate students. Its objectives are to present
an early draft of course material we have developed to
potential instructors, to critique it, and to
discuss ways of incorporating it into a college curriculum.
This material was developed for an undergraduate course in
"High-Performance Scientific Computing" under a grant from the
National Science Foundation.

Students in our course learn to use high-performance
workstations and supercomputers through laboratory exercises
representative of scientific applications.
The exercises include numerical computation, scientific visualization,
and performance measurement. Our laboratory is equipped with
DEC 5000 and SGI Indigo workstations and Xterminals; we access
supercomputers over a network.

Approximately 60% of the workshop time will be devoted to
laboratory sessions. The remainder will be devoted to tutorials on
the course material and to discussions of
how to teach this subject to undergraduates, including
practical matters of hardware and software
requirements, teaching methodology, and breadth and depth of the
subject matter.

Participants will reside in Crosman Residence Hall on the campus.
Classes and laboratory sessions will be held in the Engineering Center
located nearby. Residence expenses (room and board) will be paid by
a grant from the National Science Foundation. Transportation expenses will
not be covered.

Attendance will be limited to sixteen participants, selected according to
these criteria:

Statement of interest. This statement describes the applicant's
interest in participating in this workshop and relevant academic
experience.

Satisfying the prerequisites. The prerequisites are experience with
the Unix operating system and C or Fortran,
knowledge of undergraduate numerical analysis.

Faculty members from four-year colleges are especially encouraged to apply.
