Accelerating APL programs with SAC

摘要

The paper investigates, how SAC, a purely functional language based on C syntax, relates to APL in terms of expressiveness and run-time behavior. To do so, three different excerpts of real world APL programs are examined. It is shown that after defining the required APL primitives in SAC, the example programs can be re-written in SAC with an almost one-to-one correspondence. Run-time comparisons between interpreting APL programs and compiled SAC programs show that speedups due to compilation vary between 2 and 500 for three representative benchmark programs.
