摘要:
An apparatus is equipped with a disk block allocation optimization function for generating, if possible, an alternative disk block allocation for a current disk block allocation that will yield improved overall access time for a sequence of file accesses. The function includes logic for tracing the sequence of logical file accesses, then mapping the traced logical file accesses to physical disk blocks to determine the current disk block allocation, logic for generating the alternative disk block allocation, if possible, using the physical trace results, and logic for effectuating the alternate disk block allocation, if generated. In one particular embodiment, the logic for generating the alternative disk block allocation employs a random search approach, while in another embodiment, the logic for generating the alternative disk block allocation employs a heuristic approach.

An apparatus is programmed with a plurality of programming instructions for generating, if possible, an alternative disk block allocation for a current disk block allocation that will yield reduced overall power consumption for a sequence of disk accesses. In some embodiments, the programming instructions include the logic for tracing the sequence of disk accesses to determine the current disk block allocation, the logic for generating the alternative disk block allocation, if possible, using the trace results, and the logic for effectuating the alternate disk block allocation, if generated. In one particular embodiment, the logic for generating the alternative disk block allocation employs a random search approach, while in another embodiment, the logic for generating the alternative disk block allocation employs a heuristic approach.

摘要:
A computer system is equipped with an operating system having a tracer driver for generating trace data including disk locations accessed for disk accesses made by various components of the operating system during system startup/boot time. The tracer driver is loaded at an initial phase of system start-up. The computer system is further equipped with a companion disk block relocation driver for generating, if possible, an alternative disk block allocation for a current disk block allocation that will yield improved overall access time for a sequence of disk accesses. In some embodiments, the disk block relocation driver includes logic for tracing the sequence of disk accesses to determine the current disk block allocation, logic for generating the alternative disk block allocation, if possible, using the trace results, and logic for effectuating the alternate disk block allocation, if generated. In one particular embodiment, the logic for generating the alternative disk block allocation employs a random search approach, while in another embodiment, the logic for generating the alternative disk block allocation employs a heuristic approach.

摘要:
Systems, methods, and apparatus to identify and prioritize application processes in one or more subsystems. Some embodiments identifying applications and processes associated with each application executing on a system, apply one or more priority rules to the identified applications and processes to generate priority information, and transmit the priority information to a subsystem. The subsystem then matches received requests with the priority information and services the processes according to the priority information.

In some embodiments an expected value is compared with a number of times a storage device has been powered up and/or spun up. A cache disassociation is detected in response to the comparing. Other embodiments are described and claimed.
摘要:
A method, device, and computer program to generate operation codes having a maximum hamming distance between them. Utilizing these operation codes it is possible to detect errors immediately upon receipt of a first byte of data in a packet to allow the receiver to immediately act on the received data. This reduces the need for buffer space on both the transmitting and receiving devices. Further, this method reduces the latency for the receiver acting on the incoming data.
摘要:
A computer system having a memory allocation function is further programmed with a service provider for performing on behalf of a peripheral device, functions for controlling the peripheral device, uploaded by the peripheral device. A number of data structures are employed to facilitate uploading of the functions, and returning of the function results to the peripheral device. The peripheral device is constituted with logic for uploading the functions, at the peripheral device initiative, and retrieving the function results, when they become available, through the data structures.
