基於非揮發性記憶儲存系統壽命提升之高效能 索引管理策略

為了解決SQL online test的問題,作者唐 吉 這樣論述:

近年來非揮發性記憶體已逐漸成熟,而其良好的特性(如:高儲存密度、低靜態功耗等)為大數據儲存系統開闢了新的可能性。然而,非揮發性記憶體的耐久度與傳統記憶體相比十分有限,甚至持續惡化,因此利用磨損平衡技術來增加非揮發性記憶體的壽命已成為非揮發性存儲系統設計中的一個主要問題。更糟的是,由於嵌入式系統的資料管理系統通常使用索引方案來維護小數據,這使得非揮發性記憶體的耐久度問題更加嚴重;也就是說非揮發性記憶體的壽命在嵌入式系統中很快就會耗盡。因此,許多先前的文獻著重於重新思考基於非揮發性記憶體的系統上的索引和資料管理方案。而先前多數的研究主要集中在減少記憶體和儲存裝置中的寫入次數及降低寫入放大問題。不

幸的是,僅考慮寫入次數並無法有效延長非揮發性記憶體的使用壽命,因為這樣的解決方案無法在設備中均勻分配寫入流量。基於這樣的觀察,本研究為非揮發性記憶體和固態硬碟系統提出了兩種替代索引方案,分別為waB+tree 以及waLSM-tree。其中waB+tree 的設計考慮了B+-tree 結構內每個節點的更新頻率,從而將寫入流量均勻地分散到非揮發性記憶體的單元中。另一方面,waLSM 則考慮LSM 樹中的每個級別之間的不同數據溫度,進而在整個固態硬碟中均勻擦除所有塊。根據我們的實驗結果,本研究所提出的索引方案可有效提升裝置的耐久度,進而延長裝置的壽命

高平行細粒度Sort-Merge Join演算法於近記憶體平台研究

為了解決SQL online test的問題,作者林博彥 這樣論述:

即時處理在數據庫系統中對於揭示大數據中隱藏信息是非常關鍵的,此技術被廣泛應用於金融分析和深度學習等各個領域。然而,當今數據量仍在飛速地成長。 JOIN運算是數據查詢中的基本操作之一,在數據分析中非常重要,因為它幾乎佔據了 TPC-H標準數據庫測驗時間中平均一半的執行時間。在現代數據庫中,計算引擎和系統內存之間的數據傳輸 已經成為主要的性能挑戰之一。先前有關 Near Memory Computing NMC的文件中已經減少了許多昂貴的數據傳輸,但這些設計在處理流程和數據管理方面仍然效率低下。在本文中,我們提出了 FG-SMJ:一種基於近記憶體內高度平行且細粒度地排序合併數據運算。新穎的數據佈

局 與數據處理 使我們能夠以細粒度地且芯片等級地平行性存取芯片內的數據並大大提昇記憶體的頻寬。最為關鍵的數據訪存時間顯著減少98.48%。與之前的 NMC 設計相比,所提出的 FG-SMJ 實現了 3.08 倍的加速度 。
