The result is satisfactory still . solution obtained is physically realistic because of the asoidance of assumptions made purely for mathematical tractability by usual methods 所得結(jié)果還是令人滿意的,因?yàn)樵谇蠼膺^程中避免一些為在數(shù)學(xué)上易求解所作的假設(shè)。
Existed analytical performance models are always based on unrealistic assumptions for the purposes of mathematical tractability , such as only two processors are considered or ignorance of communication delays and rollback costs Pads已有的解析性性能模型往往為了數(shù)學(xué)推導(dǎo)的方便,基于一些不實(shí)際的假設(shè),有的僅在兩個(gè)處理器上推導(dǎo),有的忽略了通訊延遲和狀態(tài)保存開銷。
