For different optimization phases, different heuristic algorithms were adopted to determine the processor number of each task in a parallel system. 對不同的優(yōu)化階段，用不同的啟發(fā)式演算法確定一個(gè)并行系統中每個(gè)任務(wù)的處理機數。
Given that single piece of information, the compiler's optimization phase can make the appropriate choice whenever a speed versus size tradeoff is encountered. 設置一些優(yōu)化方面的信息，編譯器在優(yōu)化階段當碰到運行速度和代碼長(cháng)度要折衷時(shí)能能夠做出適當選擇。
