Adaptive optimization for self: reconciling high performance with exploratory programming

Unfortunately, crossing abstraction boundariesoften incurs a substantial run-time overhead in the form of frequent procedure calls. Thus, pervasive use of abstraction,while desirable from a design standpoint, may be impractical when it leads to inefficient programs.Aggressive compiler optimizations can reduce...

A Third-Generation SELF Implementation: Reconsiling Responsiveness with Performance

Conference on Object-Oriented Programming Systems, Languages, and Applications, 1994

Programming systems should be both re- sponsive (to support rapid development) and efficient (to ... more Programming systems should be both re- sponsive (to support rapid development) and efficient (to complete computations quickly). Pure object-ori- ented languages are harder to implement efficiently since they need optimization to achieve good perfor- mance. Unfortunately, optimization conflicts with in- teractive responsiveness because it tends to produce long compilation pauses, leading to unresponsive pro- gramming environments. Therefore, to achieve good

Type feedback vs. concrete type inference

We directly compare the two techniques, evaluating their effectiveness on a suite of 23 S&#39;s automatic coercion of machine integers to arbitrary-precision integers upon overflow confounds type inference and slows down arithmetic-intensive benchmarks.We discuss several other issues which, given the

Most of the programs are real- world applications with high demands on the memory system. For each program, we measured as much low level data as possible, including age and size distribution, type distribution, and the overhead of object alignment. Among
