Apparatus and methods for performing computer system maintenance and notification activities in an opportunistic manner
The present invention concerns methods and apparatus for performing computer system maintenance and notification activities in an opportunistic manner during time periods identified by a user when the user expects not to be using the computer system. In methods and systems of the present invention, the user prioritizes computer system maintenance activities from high to low. When an opportunity arises to perform maintenance activities due to the user, for example, being away from the computer, the user specifies the length of time the user expects to be away from the computer using apparatus of the present invention. Methods of the present invention then initiate computer system maintenance activities beginning with the highest-priority maintenance activity that can be completed during the time period identified by the user. The method continues performing maintenance activities from highest to lowest priority for so long as there is enough time remaining to perform the next maintenance task. In the present invention notification activities using the computer system resource can be performed in an opportunistic manner. For example, in the present invention a user can specify a length of time the user expects to be away from the computer; during this period the computer system would automatically generate an “away from my desk” reply to anyone sending the user an e-mail.

A virtualization system includes an information handling system with a power detector that detects a power level of the information handling system and another power detector that detects another power level of the information handling system, a power status module, and a virtual machine manager that starts workloads on the information handling system. The power status module receives the power levels and sends the power levels to the virtual machine manager. The virtual machine manager apportions a first portion of the first power level to the first workload, apportions a second portion of the first power level to the second workload, apportions a first portion of the second power level to the first workload, and apportions a second portion of the second power level to the second workload.
Routing across a virtual network
A data center can share processing resources using virtual networks. A virtual machine manager (10) hosts one or more virtual machines (11, 411), the virtual machines forming part of a segmented virtual network (34). Outgoing messages from the virtual machines have an intermediate destination address of an intermediate node in a local segment of the segmented virtual network, and the virtual machine manager has a router (18) for determining a new intermediate destination address outside the local segment, for routing the given outgoing message. By having the router as part of the virtual machine manager rather than having only a switch in the virtual machine manager, the need for virtual machines for implementing gateways is avoided. This can reduce the number of “hops” for the message between virtual entities hosted, and thus improve performance. This can help a service provider to share physical processing resources of a data center between different clients having their own virtual networks.

Compiling techniques for providing limited accuracy and enhanced performance granularity
A programmable compiler detects from source code invocations of math functions that require reduced levels of accuracy, limited variable domains, or enhanced performance. The programmable compiler replaces such invocations with intrinsics from the compiler's own intrinsic library. The math function invocations are compiled into inline object code. The inline object can be subsequently optimized along with other object code through normal compiler optimization. If an accuracy requirement is beyond what any compiler intrinsic can provide, the programmable compiler preserves the invocation of the math function defined in a default library.
Optimizing scalar code executed on a SIMD engine by alignment of SIMD slots
A mechanism is provided for optimizing scalar code executed on a single instruction multiple data (SIMD) engine by aligning the slots of SIMD registers. With the mechanism, a compiler is provided that parses source code and, for each statement in the program, generates an expression tree. The compiler inspects all storage inputs to scalar operations in the expression tree to determine their alignment in the SIMD registers. This alignment is propagated up the expression tree from the leaves. When the alignments of two operands in the expression tree are the same, the resulting alignment is the shared value. When the alignments of two operands in the expression tree are different, one operand is shifted. For shifted operands, a shift operation is inserted in the expression tree. The executable code is then generated for the expression tree and shifts are inserted where indicated.

Image browsing device, image browsing method, image browsing program, and image browsing system
The present invention relates to an image browsing device that, in an amusement park, shoots a user who is riding a ride-on, and makes the user browse the shot image at a place where the user gets off the ride-on. Firstly, when plural users direct their ID cards to the ID readers (11) respectively, users ID, ride-on number, seat numbers are made to correspond to each other to be stored in an image management device (21). When an image photographing device (12) shoots an image including a ride-on (43) and the plural users, the image management device (21) stores the image shot by the image photographing device (12), and relates the ride-on number, users ID, seat numbers to the image to store thus related information as image information. When the user browses the image, the user sets the ID card close to radio communication units (52), and, in the previously shot image, the image of a seat position related to the ID card is highlighted to be displayed. Accordingly, it becomes possible to easily specify the user who is shot in the previously shot image.
Interface and method for extensible grouping of screen elements in real time
When a set of screen elements are identified as a family a bounded extent is placed around the identified elements. Items can be automatically grouped based on their association with a set of data defined in a DBMS as a family, for example. When one of the elements within the group is moved, the extent automatically resizes to a new geometry that fits around each of the elements within the group. If an element within the group is moved against the extent and then extended beyond the boundaries of the extent, the extent automatically resizes to cover a bigger area; if an element within the group that is against the extent is moved inside the boundary of the extent, the extent automatically resizes to cover a smaller area. It is possible to nest a set of these extensible groups within a single extensible group thereby providing maximum flexibility while still maintaining optimal flexibility. In addition, it is possible to “unlink” an item so that it maintains its association with the group but does not effect the extent.
Redirection of a message to an alternate address

System and method for backing up data
A hash-optimized backup system and method takes data blocks and generates a probabilistically unique digital fingerprint of the content of each data block using a substantially collision-free algorithm.

Only if the generated fingerprint does not match a stored fingerprint is the data block backed up, at which point the generated fingerprint is added to the database of stored fingerprints. Because the algorithm is substantially collision-free, there is no need to compare actual data content if there is a hash-value match. The process can also be used to audit software license compliance, inventory software, and detect computer-file tampering such as viruses and malware.
Multi-machine atomic seamless migration
A technique migrates data from source arrays to target arrays. The array devices operate in either active mode, passive mode, or stalled-active mode.

If so, the technique involves operating the target devices in active mode and transferring data from the source devices to the target devices to enable the host to access the host data from the target arrays using the MPIO software. However, if a source device remains passive, the technique involves providing passive-to-active instructions to transition the source devices back to active to enable the host to access the host data from the source arrays.
