Abstract: An approach is provided by a mobile information handling system that includes a processor, and a gyroscope, a gravity sensor, and a memory each accessible by the processor. The approach identifies, at the mobile device that is moving with a vehicle, when a rotation of the gyroscope is at a near-zero moment, and an acceleration, wherein the acceleration is detected as being on a plane that is near-perpendicular with a gravity sensed by the gravity sensor. Then the detection is made, the approach determines a direction of the vehicle as being parallel to a direction of the detected acceleration. The approach then aligns a coordinate system used in the mobile device based on the determined direction of the vehicle.

Each of the second Nodes is configured to access the GPFS using a part of the HDFS data structure received from the client.

Abstract: A technique for efficiently processing resource allocation requests in an on-demand environment. When a user logs into a resource allocation request manager, various resource requirements entered are immediately sent to a remote resource manager to allow for dynamic, real-time feedback to the user who is entering the resource requirements as to any issues or concerns regarding the requested resource(s) or plug-in element(s), such as lack of availability. The user can thus reconfigure or otherwise modify the various resource requests based on this feedback to optimize the overall resource allocation request. This also allows an organization providing services such as computer hosting services to re-allocate resources in advance if a new resource request would exceed a service level agreement outlined in advance with a customer, thereby improving resource planning in a data center environment.
