Abstract: A method and technique for updating firmware on a multi-protocol network adapter includes: reading parameter values for a firmware update to determine an update scope indicating one or more functions of the network adapter affected by the firmware update and a write scope indicating which of the one or more functions should receive a write request for writing the firmware update to the network adapter. The update tool is operable to: send a message indicating to the one or more functions based on the update scope that a firmware update process is beginning; send a write request to write the firmware update to the one or more functions based on the write scope; send a reset request to reset the one or more functions to activate the firmware update; and send a message indicating to the one or more functions that the firmware update process is completed.

Abstract: A computer system, method, and program product for dynamically allocating storage bandwidth in an exchange is provided. The method provided creates, by an exchange server, a total inventory of resources for auction, whereby the total inventory of resources for auction includes resources from at least one provider. The total inventory of resources for auction is broadcast to at least one bidder. The amount of a resource is awarded to the at least one bidder at an end of a bidding interval, based on a bid provided by the at least one bidder during the bidding interval, where the amount of the resource is a portion of the total inventory of resources for auction.

Abstract: The present disclosure includes a method for migration of a first virtual function of a first device located on a PCI bus and accessible by a device driver using a virtual address. A second virtual function is created on a second device. A base address is determined for the second virtual function as a function of a logical location of the second device within the PCI structure. An offset is determined for the second virtual function as a function of the base address and the virtual address. The device driver is notified that the first virtual function is on hold. The offset is stored in a translation table. The device driver is notified that the hold has been lifted. Accesses to the virtual address and by the device driver to memory of the second virtual function are routed based upon the offset in the translation table.

Abstract: An approach is provided that collects data from a multi-function adapter that is used by multiple functions. In the approach, a master function is dynamically selected from the group of functions. The approach further allows the master function to perform a disruptive adapter data collection while inhibiting performance of disruptive adapter data collection processes by the other (non-master) functions.

Abstract: Mechanisms are provided for generating a system dump data structure based on device state data. A system dump operation is initialized in a data processing system and a device dump is requested by a dump manager from a device coupled to the data processing system. A collection scope data structure and disruption vector corresponding to the device are retrieved. The collection scope data structure specifies a set of one or more functions in the device for which to collect state data. The disruption vector specifies, for each of the one or more functions, a corresponding level of disruption that will be caused by the device dump. The device dump data is collected from the device in accordance with the collection scope data structure and the disruption vector and the system dump data structure is generated based on the collected device dump data.

Abstract: There is set forth herein a computer program product, computing device, and method for displaying an email message. In one example, a computing device receives an input comprising at least one criterion for redacting email messages; stores the at least one criterion in a configuration of a client computer program; receives an email message having a field, the field comprising a first content; determines whether a condition of at least one of the email message and a current state of the computing device satisfies the at least one criterion stored in the configuration of the client computer program; and, in response to determining that the condition satisfies the at least one criterion, displays a second content in place of the first content in a user interface of the client computer program, wherein the second content is different than the first content.

Abstract: Page faults during partition migration from a source computing system to a destination computing system are reduced by assigning each page used by a process as being hot or cold according to their frequency of use by the process. During a live partition migration, the cold or coldest (least frequently used) pages are copied to the destination server first, followed copying the warmer (less frequently used) and concluded by copying the hottest (most frequently used) pages. After all dirtied pages have been refreshed, cutover from the instance on the source server to the destination server is made. By transferring the warm and hot pages last (or later) in the migration process, the number of dirtied pages is reduced, thereby reducing page faults subsequent to the cutover.

Abstract: Personal digital assistant devices are provided that query power subsystems to determine a level of battery power currently available for operating processes, and further determine a number of screen display changes that may be effected on a persistent display device at that determined level. If the determined number of screen display changes that may be effected at the determined level of available battery power fails to meet a specified minimum threshold number of images, the processing unit powers down subsystems of the personal digital assistant device and causes a highest listed image of a prioritized list of screen image instances to be displayed on the persistent display device, which persistently displays the image after a loss of power.

Abstract: A computer identifies a relationship among a subset of a set of data blocks, a basis of the relationship forming a context shared by the subset of data blocks. The computer selects a code data structure from a set of code data structures using the context. The context is associated with the code data structure, and the code data structure includes a set of codes. The computer computes, for a first data block in the subset of data blocks, a first code corresponding to a content of the first data block. The computer determines whether the first code matches a stored code in the code data structure. The computer replaces, responsive to the first code matching the stored code, the first data block with a reference to an instance of the first data block. The computer causes the reference to be stored in a target data processing system.

Abstract: Provided are techniques for the tracing of computer processes and, more specifically, to techniques that enable a work unit to be traced across multiple processing components. A data structure is created and associated with a work unit. The first time a unit of work is processed a tracing context is retrieved form a pool and associated with the data structure. As the unit of work is passed from component to component, the data structure is passed so that each component has access and is able to augment the same tracing context associated with the unit of work.

Abstract: A method and implementing computer system are provided which collects annotation information from users of a mapping site, associates the annotation with particular segments of a travel route, scores the annotations and constantly adjusts the scores of the annotations in determining preferred travel routes. When a user requests a route, the relationship between requestor and annotation provider is considered, and the requestor is provided with the highest-ranked annotations in accordance with the requestor's personal preferences for driving directions. The user can request updates to the annotations if their scoring changes after the route is provided. Current weather conditions and continuous weather condition updates are also provided at predetermined intervals for selected routes of travel.
