International Classification:

G06F015/16

US Classification:

709203, 709217

Abstract:

A system and method for testing server latencies using multiple concurrent users in a computer system is provided. A computer system may include a server and one or more clients. Multiple users may be created in the system such that each user may login to the server. The server may include a directory for each user and the directory for each user may be populated with a mix of files according to a user type for each user. An instance of a test program may be executed for each user on one or more clients concurrently. The server may authenticate each user using the same or different operating system protocols. Each instance of the test program may be configured to cause a series of accesses to one or more files in the directory of its respective user on the server and may be configured to cause a latency value to be measured and stored for each access that is performed. The latency values may be compiled by each instance of the test program and may be stored onto the server upon completion of each instance of the test program. The latency values measured by an instance of the test program may represent a first time portion that corresponds to the amount of time to perform a given access and a second time portion that corresponds to the server verifying that the user corresponding to this instance of the test program has permission to access the file.

US Classification:

Abstract:

A system and method for configuring a control plane within a network device. One of a pair of control processors is selected to act as the master of the control plane and the other control processor is specified as a standby control processor in normal operation. In the case of a failover or switchover event, the standby control processor assumes the role of the master of the control plane and updates configuration information within line cards in the network device as necessary. A state machine within the control processor is employed to manage state transitions for the control processor. Each control processor generates at least one signal that indicates whether it is capable of serving as the master of the control plane. Master selection logic selects one of the control processors as the master for the control plane and in one embodiment advertises the identification of the master control processor via triply redundant signals. Voting logic within the control processors and other cards within the network device is employed to identify the selected master unit for the control plane.

International Classification:

G06F 1324

US Classification:

395740

Abstract:

Postponing the interrupt for an I/O event can increase system throughput by amortizing the cost of the interrupt service routine over multiple I/O events. In current systems that provide interrupt postponement, the time parameter is fixed. Fixed values can lead to parameter configuration errors, excessive characterization work to generate parameter values, and a failure to automatically re-configure to system changes or to external load changes. The proposed mechanism measures actual system experience and eliminates the parameter configuration effort by filtering its own experience to derive a target value for interrupt postponement. A current postponement value with the potentially greater variance than the target is used to rapidly respond to abrupt change in offered load. The invention also benefits tasks with real-time deadlines to provide correct system operation.

International Classification:

H04J 324

US Classification:

370 84

Abstract:

In an interactive video-on-demand system, real-time programs are encoded as a transport stream including a plurality of transport stream packets. Some of the transport stream packets include timing signals indicating the real time of the program. The transport stream packets are formatted into transport cells for transport over an asynchronous transfer mode network from a source to a destination. The cells are transported at a transport rate which is determined by a network clock. The transport rate is chosen to deliver the transport stream faster than the real time of the program. While transporting the transport stream, it is determined if the transport stream is being transported ahead of the real time of the program. In this case, idle cells are injected into the transport stream to have the program arrive at the destination in the real time of the program.

International Classification:

US Classification:

395706

Abstract:

A language construct that allows a software programmer to use an intermediate or high-level language command to explicitly group operations or fuse loops in a group of statements operating on parallel arrays is disclosed. The command instructs a compiler, which would otherwise add temporary variables to avoid data dependencies or perform data dependency analysis, to translate the enclosed statements directly into machine language code without adding those temporary variables and without performing any data dependency analysis. Execution of the command results in the performance of the group of statements by all of the virtual processors.

Abstract:

An aerodynamics control system for a vehicle may include a repositionable aerodynamic device disposed at a portion of the vehicle, a controller operably coupled to components or sensors of the vehicle to receive information including vehicle performance data and position information for the aerodynamic device, and a vehicle location sensor determining location information for the vehicle. The controller stores the vehicle performance data and the position information in association with the location information for each of a plurality of locations. Responsive to detecting an approach of the vehicle to one of the locations, the controller provides a control instruction to position the aerodynamic device based on recorded vehicle performance data and recorded position information associated with the one of the locations.

Abstract:

Methods and apparatus for deodorization of steam from a waste treatment autoclave. A system includes an autoclave for sterilization of waste, the autoclave being fluidly linked or coupled to a bottom portion of a condensate tank to enable flow of steam from the autoclave to the condensate tank, and a deodorization tank containing a liquid deodorant. An upper portion of the condensate tank is fluidly linked or coupled to a bottom portion of the deodorization tank to enable steam/air from the condensate tank to bubble through the liquid deodorant and exit from a vent located on a top of the deodorization tank.
