Abstract:

Systems and methods for implementing a retail transaction at a digital image forming device are disclosed. Paper and blank electronic media may be purchased at the digital image forming device. The electronic media includes CD-ROMs, DVD-ROMs and floppy disks. A computer file may be transferred to the storage media as part of the transaction. The file may be transferred from any external electronic media. The file may be transferred from any storage media controlled by a portable digital device, such as a digital camera, a cell phone, a portable computer or a PDA. Alternately, the file may be transferred from a remote storage device accessible via the Internet to either media sold at or external to and in communication with the digital image forming device.

International Classification:

G06F 11/20
G06F 9/48
H04L 12/24

Abstract:

A plurality of tasks are executed on a plurality of central processing units (CPUs) of a computational device. In response to an occurrence of an event in the computational device, one or more CPUs that are executing tasks associated with an event category to which the event belongs are stopped within a first predetermined amount of time. In response to stopping the one or more CPUs, a data set indicative of a state of the computational device is collected, for at most a second predetermined amount of time.

Inventors:

- Armonk NY, US
Trung N. Nguyen - Vail AZ, US
Louis A. Rasor - Tucson AZ, US

International Classification:

G06F 9/50
G06F 9/48

Abstract:

A plurality of central processing units (CPUs) are allocated as a set of dedicated CPUs for processing tasks of an input/output (I/O) resource. In response to determining that a CPU utilization for the set of dedicated CPUs is less than a first predetermined threshold, at least one CPU of the set of dedicated CPUs is configured as a reserved CPU to execute tasks for one or more entities other than the I/O resource. In response to determining that a CPU utilization for the set of dedicated CPUs is greater than a second predetermined threshold, the reserved CPU is configured as a dedicated CPU to process tasks for the I/O resource.

International Classification:

G06F 9/48

Abstract:

A plurality of dispatch queues corresponding to a plurality of processing entities are maintained, wherein each dispatch queue includes one or more task control blocks or is empty, and wherein an ordered list of dispatch queues is maintained for each processing entity of the plurality of processing entities. A state for each of the plurality of dispatch queues is determined and the determined state is compared to a desired state for the plurality of dispatch queues. A task control block is moved from one dispatch queue to another dispatch queue, in response to the comparing of the determined state to the desired state for the plurality of dispatch queues.
