　　在快速解決計算量大、數(shù)據(jù)密集型問題時，人們越采越認(rèn)識到并行處理是惟一節(jié)省成本的方法。價格低廉的并行計算機（如商用桌面多處理機和工作站機群）的出現(xiàn)，使得這種并行方法的適用范圍越來越廣?，F(xiàn)在已經(jīng)為可移植的并行程序設(shè)計制定了專門的軟件標(biāo)準(zhǔn)，為并行軟件的大幅度發(fā)展打好了基礎(chǔ)。事務(wù)處理。信息檢索．?dāng)?shù)據(jù)挖掘和分析以及多媒體服務(wù)等數(shù)據(jù)密集型應(yīng)用已經(jīng)為當(dāng)代的并行平臺提供了新的挑戰(zhàn)。計算生物學(xué)和納米技術(shù)等新興的領(lǐng)域?qū)Σ⑿杏嬎愕乃惴ê拖到y(tǒng)開發(fā)提供了前瞻性的啟示，而體系結(jié)構(gòu)，編程模型和應(yīng)用中的變化對如何使用戶以網(wǎng)格服務(wù)形式得到并行平臺也提供了一些啟發(fā)。本書討論了這些新技術(shù)的發(fā)展，也覆蓋了并行計算機處理的較傳統(tǒng)的問題．本書盡可能采用與體系結(jié)構(gòu)無關(guān)的觀點來對待抽象模型的底層平臺和設(shè)計算法。書中選擇MPI（MessagePassingInterface）、POSIX線程和OpenMP作為編程模型，并在不同例子中反映了并行計算的不斷變化的應(yīng)用組合。本書的主要特點：全面介紹并行計算的每個方面（體系結(jié)構(gòu)，編程范型。算法和標(biāo)準(zhǔn)）既講述傳統(tǒng)的計算機科學(xué)算法（排序，搜索。圖和動態(tài)編程算法），也講述科學(xué)計算算法（矩陣計算、FFT）介紹MPI、Pthreads和OpenMP這三個應(yīng)用最廣泛的編寫可移植并行程序的標(biāo)準(zhǔn)適合作為高等院校并行計算。并行編程，并行算法的設(shè)計和分析以及高性能計算課程的本科生和研究生的教材作者簡介AnanthGrama普度大學(xué)計算機科學(xué)系的副教授，研究領(lǐng)域是并行和分布式系統(tǒng)和應(yīng)用的不同方面。AnshuIGUptaIBMT．J．WatsonResearchCenter的研究人員，研究領(lǐng)域是并行算法和科學(xué)計算．GeorgeKarypis明尼蘇達大學(xué)計算機科學(xué)和工程系的副教授，研究領(lǐng)域是并行算法設(shè)計、數(shù)據(jù)挖掘和生物信息學(xué)等。VipinKumar明尼蘇達大學(xué)計算機科學(xué)和工程系的教授和軍用高性能計算研究中心的主管．研究領(lǐng)域是高性能計算。用子科學(xué)計算問題和數(shù)據(jù)挖掘的并行算法。
