This paper evaluates performance characteristics of the Compaq ES40 shared memory multiprocessor. The ES40 system contains up to four Alpha 21264 CPU’s together with a high-perf...
Estimates of predicate selectivities by database query optimizers often differ significantly from those actually encountered during query execution, leading to poor plan choices a...
The negative performance impact of branch mis-predictions can be reduced by exploiting control independence (CI). When a branch mis-predicts, the wrong-path instructions up to the...
Trace-driven simulation of superscalar processors is particularly complicated. The dynamic nature of superscalar processors combined with the static nature of traces can lead to l...
—This paper explores the use of compiler optimizations which optimize the layout of instructions in memory. The target is to enable the code to make better use of the underlying ...
