Key takeaways

Steve Wallach belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Steve Wallach to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Steve Wallach from memory before moving on to harder problems.

Reference excerpt

Steven "Steve" J. Wallach (born September 1945 in Brooklyn, New York) is an engineer, consultant and technology manager. He is a Seymour Cray Computer Engineering Award recipient.

Education Wallach received his BS in electrical engineering from Polytechnic University in Brooklyn, his MS in electrical engineering, from University of Pennsylvania and an MBA from Boston University.

Career Wallach retired from Micron, and is currently a guest scientist at LANL (Los Alamos). He is also a visiting scientist at the Barcelona Supercomputer Center (BSC). Main focus on HPC RISC-V technology. Wallach was the co-founder and CTO of Convey Computers. After Micron Technology bought Convey, Wallach became a design director. Wallach was previously Vice President of technology for Chiaro Networks and was co-founder of Convex Computer, their Chief Technology Officer and Senior V.P. of Development. After Hewlett-Packard bought Convex, Wallach became the chief technology officer of Hewlett-Packard's large systems group. He was also a visiting professor at Rice University from 1998–1999. Prior to Convex, he was manager of Advanced Development for Data General. His efforts on the MV/8000 are chronicled in Tracy Kidder's Pulitzer Prize winner The Soul of a New Machine. Prior to that, he was an engineer at Raytheon, where he worked on the All Applications Digital Computer (AADC). Wallach has 105 American patents and is a member of the National Academy of Engineering, a IEEE Fellow and was a founding member of PITAC (The Presidential Information Technology Advisory Committee). He is currently an adviser to Centerpoint Venture partners, Sevin Rosen Funds, and Interwest, and a consultant to the United States Department of Energy Advanced Scientific Computing (ASC) program at Los Alamos National Laboratory. He donated his personal library of papers and engineering notebooks to the Computer Museum. In 2023 he was interviewed by the ACM History Committee

Awards Wallach was awarded in 2008 Seymour Cray Computer Science and Engineering Award for his "contribution to high-performance computing through the design of innovative vector and parallel computing systems, notably the Convex mini-supercomputer series, a distinguished industrial career and acts of public service." In 2002 he received the IEEE Computer Society Charles Babbage Award. Member Eta Kappa Nu & Tau Beta Pi. In 2024 he was named as one of the HPC legends.

Worked examples

Example 1 — a first encounter with Steve Wallach

Start with the simplest possible case. Write down what Steve Wallach claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Steve Wallach before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Steve Wallach ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Steve Wallach

In research: Steve Wallach appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Steve Wallach in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Steve Wallach is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 births, American chief technology officers, American consultants, so understanding it makes those chapters shorter.
In everyday life: Look for Steve Wallach outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
