TL;DR: PSTORM (systematic tailored ORF-data retrieval and management) combines protein analyses of BLAST, Fasta, Pfam and ProtParam on a batch file of protein sequences to summarise and organise the output in an Access database format.
Abstract: STORM (systematic tailored ORF-data retrieval and management) combines protein analyses of BLAST, Fasta, Pfam and ProtParam on a batch file of protein sequences. It subsequently summarises and organises the output in an Access database format.

20 May 2019TL;DR: A novel batch-file access approach is proposed, referred to as BFO for its set of optimized Batch-File Operations, by developing novel BFOr and BFOw operations for fundamental read and write processes respectively, using a two-phase access for metadata and data jointly.
Abstract: Existing local file systems, designed to support a typical single-file access pattern only, can lead to poor performance when accessing a batch of files, especially small files. This single-file pattern essentially serializes accesses to batched files one by one, resulting in a large number of non-sequential, random, and often dependent I/Os between file data and metadata at the storage ends. We first experimentally analyze the root cause of such inefficiency in batch-file accesses. Then, we propose a novel batch-file access approach, referred to as BFO for its set of optimized Batch-File Operations, by developing novel BFOr and BFOw operations for fundamental read and write processes respectively, using a two-phase access for metadata and data jointly. The BFO offers dedicated interfaces for batch-file accesses and additional processes integrated into existing file systems without modifying their structures and procedures. We implement a BFO prototype on ext4, one of the most popular file systems. Our evaluation results show that the batch-file read and write performances of BFO are consistently higher than those of the traditional approaches regardless of access patterns, data layouts, and storage media, with synthetic and real-world file sets. BFO improves the read performance by up to 22.4× and 1.8× with HDD and SSD respectively; and boosts the write performance by up to 111.4× and 2.9× with HDD and SSD respectively. BFO also demonstrates consistent performance advantages when applied to four representative applications, Linux cp, Tar, GridFTP, and Hadoop.

TL;DR: This third edition addresses the changes faced by current generation DOS power users, such as Windows, Norton Utilities and a wide range of sophisticated hardware and contains proven strategies for maximizing productivity with DOS 5, using Windows 3 with DOS, managing memory effectively and using Epson and HP laserjet printers.
Abstract: This third edition addresses the changes faced by current generation DOS power users, such as Windows, Norton Utilities and a wide range of sophisticated hardware. It is aimed at the many thousands of intermediate to advanced DOS users who want optimal PC performance. The book contains proven strategies for maximizing productivity with DOS 5, using Windows 3 with DOS, managing memory effectively and using Epson and HP laserjet printers. Scores of new batch files and examples enhance the discussions.

TL;DR: In this article, a method for quickly operating a file of a smart phone comprises: the smart phone enabling a file batch selection function according to an operation of a user; when the file selection function is enabled, the smart mobile selecting a file and/or a folder on a corresponding position according to a sliding track of a finger or a touch pen on the touch screen; and the smart smartphone performing a user-selected operation on all selected files and or folders.
Abstract: A method for quickly operating a file of a smart phone comprises: the smart phone enabling a file batch selection function according to an operation of a user; when the file batch selection function is enabled, the smart phone selecting a file and/or a folder on a corresponding position according to a sliding track of a finger or a touch pen on the touch screen; and the smart phone performing a user-selected operation on all selected files and/or folders. A smart phone comprises a touch screen and a file processor, and the file processor comprises a batch selection enabling and disabling module, a file batch selection module, and a file batch operation module. In embodiments of the present invention, a file is operated conveniently and quickly by using the touch screen of the smart phone, achieving a significant effect particularly in processing large numbers of files.

28 Jan 2011TL;DR: In this article, the authors proposed a method to reorder the original read order sequence by selectively adding pages from a pagelist to a batch such that when the batch is executed as a read operation, each page in the batch can be concurrently accessed.
Abstract: Systems and methods are disclosed for increasing efficiency of read operations by selectively adding pages from a pagelist to a batch, such that when the batch is executed as a read operation, each page in the batch can be concurrently accessed. The pagelist can include all the pages associated a read command received, for example, from a file system. Although the pages associated with the read command may have an original read order sequence, embodiments according to this invention re-order this original read order sequence by selectively adding pages to a batch. A page is added to the batch if it does not collide with any other page already added to the batch. A page collides with another page if neither page can be accessed simultaneously. One or more batches can be constructed in this manner until the pagelist is empty.
