摘要： In one embodiment, a method includes receiving a list of applications that are anticipated to access a given data block within a time window with an anticipated future access count for each anticipated application. The method also includes determining that a block application access weight is greater than a block application access threshold, the block application access weight being based at least in part on the anticipated future access count for each anticipated application. The method further includes determining that a cache profile weight for the given data block is greater than zero contingent upon the block application access weight being greater than the block application access threshold. Moreover, the method includes sending the cache profile weight to a file system contingent upon the cache profile weight being greater than zero. Other methods, systems, and computer program products are described in accordance with more embodiments.

摘要： A file division and erasure code application executing in a controlling computational device generates data fragments and parity fragments of a file. Each of the generated data fragments and parity fragments are distributed in a different distributed computational device of a plurality of distributed computational devices, where distributing of a generated data fragment comprises determining whether any distributed computational device already stores a duplicate copy of the generated data fragment, and if any distributed computational device already stores the duplicate copy of the generated data fragment, placing the generated data fragment in the distributed computational device if no other data or parity fragment of the file has already been placed in the distributed computational device.

摘要： An approach is provided for operating a mobile device having first and second operating systems (OSs) installed. While executing the first OS but not the second OS and based on battery power remaining in the mobile device being less than a threshold and the mobile device consuming less power if executing the second OS but not the first OS, execution of the first OS is terminated and the second OS is executed. While executing the second OS, and in response to a determination of a likelihood of the mobile device being subject to an external security attack in a geographic region in which the mobile device is located and a determination that the mobile device is more secure against the external security attack while executing the first OS than while executing the second OS, execution of the second OS is terminated and the first OS is executed.

摘要： In one embodiment, a method includes determining a home node that corresponds to gateway (GW) nodes in a clustered file system, each GW node being eligible to process one or more read tasks, determining a peer GW eligibility value for more than one of the GW nodes in the clustered file system eligible to process one or more read tasks, and determining a single GW node from amongst the GW nodes having a highest peer GW eligibility value for each home node. Additionally, the method includes assigning and defining a size for one or more read task items for the GW nodes having the highest peer GW eligibility value for multiple home nodes based on a current dynamic profile of the GW nodes, and distributing workload to the GW nodes according to the size for each of the one or more read task items assigned to the GW nodes.

摘要： In an approach for determining printability of an electronic file, a computer electronically receives a file for printing. The computer parses the file for one or more of text, images, and formatting indicative of potential copyrighted material. The computer, in response to identifying any text, images, or formatting indicative of potential copyrighted material, identifies potential copyrighted material within the file. The computer determines whether the file may be printed based, at least in part, on the identified potential copyrighted material. In another approach for determining printability of an electronic document, a computer electronically receives a document for printing. The computer locates attributes associated with the document and stored in a separate database, which includes one or more of the following: ownership, licensing information, printability, and number of prints allowed. The computer determines the document is printable based on the attributes and prints the document.

摘要： Software that performs the following steps is provided: (i) running an application on a first virtual machine on a first physical server, with the application including a first plurality of independently migratable elements, including a first independently migratable element that utilizes a first resource on the first virtual machine and a second independently migratable element that utilizes a second resource on the first virtual machine; and (ii) on condition that a first migration condition exists, migrating the first independently migratable element to a second virtual machine on a second physical server, such that the first independently migratable element is able to utilize a resource that is similar to the first resource on the second virtual machine on the second physical server while the second independently migratable element remains able to utilize the second resource on the first virtual machine on the first physical server.

摘要： A hierarchal storage management method is provided. The method includes detecting a first portion of a first file being deleted from a hybrid storage device including a hard disk drive (HDD) memory device, a solid state drive (SSD) memory device, and an archival storage memory device. A first set of memory blocks associated with the first portion of the first file is identified. The first set of memory blocks are determined to reside on the SSD memory device. In response, the first set of memory blocks are transferred from the SSD memory device to a first portion of the hybrid storage device.

摘要： Methods, systems, and computer program products are provided for performing a secure delete operation in a wide area network (WAN) including a cache site and a home site. A method includes identifying a file for deletion at the cache site, determining whether the file has a copy stored at the home site, detecting a location of the copy at the home site prior to a disconnection event of the cache site from the home site, deleting the file from the cache site during the disconnection event, and in response to the secure deletion of the file not being complete during the disconnection event, indicating on a table a remote inode number assigned to the copy associated with the file at the home site, a name under which the copy is saved, and a list of data chunk tuples specifying selected data of the copy to undergo secure deletion.
