Slices (not Weiser slices)
A slice is a subset of the trace information corresponding to a user-selected feature in a program
Slices intended to filter out extraneous information, focusing analysis on one area
Slices give you an extra dimension for measuring program execution
- Can compute any measurement about a program relative to any defined slice
- Ex: define slices to represent functional areas of your program; then measure execution time in each thread, method, method invocation, etc. spent in each functional area
