We present an improved method for scheduling speculative data paths which relies on cancel tokens to undo computations in misspeculated paths. Performancewise, this method is consi...
that defines abstract costs for measuring or analyzing the performance of computations, (2) to supply the users with a mapping of these costs onto runtimes on various machine model...
Automatic program comprehension is particularly useful when applied to sparse matrix codes, since it allows to abstract e.g. from specific sparse matrix storage formats used in th...
Existing profile-guided partial redundancy elimination (PRE) methods use speculation to enable the removal of partial redundancies along more frequently executed paths at the expe...
- This paper describes a symbolic formulation that allows incorporation of speculative operation execution (preexecution) in an exact control-dependent scheduling of arbitrary forw...
