I have taught this in the past, but have not kept up with the literature as well as I should have. I know of several books that cover topics of interest for such a course, but would like to have the suggestions of others to bring me up-to-date on the literature at the level of texts (e.g. Ortega; Dongarra, et al) and survey papers (e.g. the recent SIAM Review papers on methods for dense and sparse systems on parallel machines). I will compile a summary of whatever suggestions I receive, to be made available to others.

We would like to invite you to participate in this very happy occasion. A preliminary outline of the schedule for that day, Saturday, February 29, 1992, is as follows: On Friday evening, Feb. 28 the IMA will sponsor a buffet reception/dinner at the Campus Club, on the University of Minnesota Campus. On Saturday, Feb. 29, during the day, a workshop of a more historical or anecdotal nature will take place on the University Campus. Jack Dongarra and Paul Van Dooren are handling the details of the program. If you would like to contribute to the informal talks addressing Gene's impact on various areas of research, his unique style of interacting with people, his travel habits, anecdotes, a survey of areas where he has had an impact, etc, please contact either Jack (dongarra@cs.utk.edu) or Paul (vdooren@uicsl.csl.uiuc.edu) as soon as possible, but in any case before November 30th. On Saturday Evening, we will hold a Banquet in the tradition of Gene (that's right - at a Chinese restaurant!). Bill Gear will the after dinner speaker. We plan to provide bus transportation to the Restaurant. To help defray part of the expenses for Friday and Saturday, we will have to charge individual participants $15 per person (this includes the transportation and banquet). Hotel rooms are available at the Day's Inn, about 4 blocks from Campus, at the special rate of $34/night (plus tax). Please call them directly to reserve your room. The special rate is being held only until Feb. 9, 1992. You should be able to guarantee your reservation with a credit card. The address/phone number is Day's Inn University 2407 University Ave. S.E. Minneapolis, MN 55414, USA phone (612)-623-3999 or (612)-623-4262 (when making reservations, ask for Joyce Turner, or state that you are visiting the Institute of Mathematics and its Applications) If you would like to attend the celebration and banquet, we would like to hear from you by January 15th, 1992. Please send e-mail to boley@cs.umn.edu to receive a copy of an registration form. I apologize for the lack of a personal reply to all you folks who sent me a message expressing interest in this workshop. We look forward to hearing from you.

He is working at the Center for Informatics and Computer Technology at the Bulgarian Academy of Sciences. He is interested in (i) finite elements with emphasis on local refinement, (ii) domain decomposition, and (iii) linear algebra. He has done also some research on parallel algorithms for computers with shared memory (they have transputers at the Center for Informatics and Computer Technology). He is interested in research connected with parallel computers (not only computers with shared memory). The Bulgarian Academy of Sciences is the highest research institute in Bulgaria. The best students from the universities are selected for the Bulgarian Academy of Sciences. In the Center for Informatics and Computer Technology they are now very interested in establishing contacts with universities and research institutes in the Western countries. If anybody knows about a suitable position, contact me, please and I shall pass some more information. Thank you very much in advance.

Leading software developers from government, industry and academia will make presentations at the workshop. The first sessions will be held in the Mariott Library Auditorium on on campus. The second day of the conference will be held at the University Park Hotel, which is adjacent to the campus. The second day will be a joint meeting with the Future Technologies Cluster Users Group (CUG) sponsored by IBM's Advanced Workstation Division in Austin, Texas (the designers and manufacturers of the RS/6000 line of scientific workstations). The field of distributed computing encompasses topics that range from distributed database systems and remote graphical display to clustered computing. The scope of the workshop is limited to the latter area, which is concerned with the use of scientific workstations connected by local area networks for parallel and batch processsing. The primary objectives of the workshop are to educate the user community on current activity in clustered computing and to help researchers and programmers evaluate the potential impact of clustered computing on their work. To achieve these objectives, speakers at the workshop will focus on issues such as the usefulness, cost and availability of tools for accomplishing clustered computing. Among the topics that will be addressed are message-passing libraries, parallel compilers, network debuggers, graphical user interfaces and performance analysis tools. Case studies drawn from the experiences of researchers will also be included.
