Does anyone know how many Floating Point Operations (FLOPS) CPLEX uses to solve a MIP
Lots.

or how to approximate the maximum computational burden that CPLEX might have on my cluster?
Doesn't the cluster provide a way to ration CPU cycles? (Sorry if it's a silly question; I've never used a cluster.) You can certainly set an execution time limit within CPLEX.

My university wants to know the computational requirements of cplex in FLOPS. I saw some papers from the '90s that stated 5 GigaFLOPS, but nothing more recent. Any ideas?
Total number of floating point operations is obviously going to depend heavily on the problem -- and, while it's generally true that bigger problems tend to eat more CPU cycles, there's no useful formula I know of to predict floating point ops from problem dimensions.
