Nick Higham 's Numerical Linear Algebra group at the University of Manchester is hosting a conference celebrating Jack Dongarra' s 70th birthday out 7 and 8. I amGiving a talk, virtually, on out 7. I plan to reminisce about how I did computing in the days before everybody had their own computer in their lap. Here are the slides TAB for a talk, notes, and some links to this blog for more details.

These computers that have had a vital part of my professional life.

Contents

Caltech and University of Utah, 1959 and 1960

Burroughs 205 Datatron

For the story of the only Burroughs 205 computer with a "skip on minus" instruction, see Cleve 's Corner blog,"My First Computer".

At first, we programmed in purely numeric machine language. Here is a sample program, a portion of an accounting application, seems the from the Burrough 's 205 User guide.

The Jet Propulsion that 1960-1961

IBM, the IBM 709, 7094

Worked for Chuck Lawson for two summers. Introduced to Fortran. For the story of a FLOP, see Cleve 's Corner blog,".

Informs the punched CARDS.

Stanford, 1961-1965

Burroughs, 220 Burroughs Algol 58.

Burroughs, 5500 full Algol.

The IBM 7090, Algol - W, ORVYL and WYLBUR

The CDC 1604. The First accurate computation of the eigenvalues of the L - shaped. Be lambda_1 = 9.6397238445. See Cleve 's Corner blog,MathWorks Logo.

University of Michigan, 1966-1972

IBM 360/67. MTS, Michigan Timesharing System. The First interactive demo of matrix computation. To the to Wallace Givens at Argonne.

Argonne, 1970 s

Intel IPSC, 1985

Commercialization of Caltech Cosmic Cube developed by Chuck Seitz and Geoffery Fox. One board, essentially an IBM PC with 80286 CPU, the an of 80287 math coprocessor, 256 k memory. The Hypercube interconnect, d5, d6, d7 with 32, 64, 128 nodes. The Very basic message passing software.
