Early Bird Registration is still open.
INFORMS is the acronym for the Institute for Operations Research and the Management Sciences. Many computer system performance analysis concepts, e g., queueing models, OS scheduling, and capacity forecasting, fall under the formal subject of Operations Research: a strange name that has its roots in WW-2 logistics planning.
Amazingly, performance analysis (done right) is often not technology-dependent, per se. The right abstraction can remain invariant into perpetuity. For example, my 2025 analysis of the GPT Efficient Computer Frontier (ref. 8 in paper 1) is based partly on my 1989 analysis of virtual memory thrashing in paper 53. Same paradigm; vastly different context.
The connection between the two papers is by no means obvious but, quite striking (not to mention satisfying) when you realize it.
This topic goes back to my M.Sc. thesis, when my supervisor, Prof. Christie Eliezer (2nd from left in the photo), who was one of Dirac's very few research students, told me about the Dirac-Sommerfeld paradox. He thought it might be pertinent to my thesis.
Being a physics "genius", I didn't pursue it because I assumed it had been resolved by more modern developments like, Quantum Field Theory — a subject that neither Eliezer nor I knew much about. I was wrong. Very wrong!
