Abstract: One embodiment of the present invention supports execution of a start transactional execution (STE) instruction, which marks the beginning of a block of instructions to be executed transactionally. Upon encountering the STE instruction during execution of a program, the system commences transactional execution of the block of instructions following the STE instruction. Changes made during this transactional execution are not committed to the architectural state of the processor until the transactional execution successfully completes.

Abstract: In a method for dynamic allocation of memory address space, an original version of a program is executed. This execution includes the execution of a request to use memory address space occupied by an optimized version of the program that is protected from modification. When this request is detected, execution control is passed to an optimization code that was used to define the optimized program. The optimization code copies a portion of the optimized program residing in the memory address space requested by the original program, writes the copied portion to unallocated memory address space, and adjusts the code of the optimized program. The protection of the copied portion of the optimized program is released, and execution control is returned to the original program. The request to use the memory address space occupied by the portion of the optimized for which the protection has been released is then re-executed.

Abstract: One embodiment of the present invention provides a system that determines a severity of degradation in a signal. During operation, the system receives signal values for the signal, wherein the signal values are received with a constant sampling interval. Next, for each received signal value, the system applies a Sequential Probability Ratio Test (SPRT) to the signal value. If the SPRT generates an alarm on the signal value, the system increments a cumulative counter which records a running total number of the SPRT alarms. Upon receiving each signal value, the system updates a cumulative function using a value in the cumulative counter. Next, the system determines the severity of degradation in the signal from the shape of the cumulative function.

Abstract: One embodiment of the present invention provides a system that selectively monitors load instructions to support transactional execution of a process, wherein changes made during the transactional execution are not committed to the architectural state of a processor until the transactional execution successfully completes. Upon encountering a load instruction during transactional execution of a block of instructions, the system determines whether the load instruction is a monitored load instruction or an unmonitored load instruction. If the load instruction is a monitored load instruction, the system performs the load operation, and load-marks a cache line associated with the load instruction to facilitate subsequent detection of an interfering data access to the cache line from another process. If the load instruction is an unmonitored load instruction, the system performs the load operation without load-marking the cache line.

Abstract: A method and device for managing a data buffer that stores packets for transmission. Packets are loaded into the data buffer, which is managed as a first-in-first-out (FIFO) circular queue, at the tail of the queue. Three sequence numbers index a pointer array addressing the buffer. These sequence numbers correspond to the tail of the queue, the point in the queue from which the next packet is to be transmitted and the head of the queue, corresponding to the last packet acknowledged as correctly received plus one. When a packet is negatively acknowledged, the sequence number corresponding to the next packet to be transmitted is reset to the head of the queue.

Abstract: A method is provided for safely editing a binary code to be executed on a computer system. The method allows the binary code to be directly edited without compromising its integrity. More specifically, a larger binary code is transformed into a number of smaller binary code segments having sizes within a reference range of a control transfer function such as a branch instruction. A branch slamming operation can then used to displace a binary instruction contained within a smaller binary code segment with a branch instruction referring to a binary patch that is appended to the smaller binary code segment. The binary instruction displaced by the branch instruction is preserved in the binary patch. Upon completion of the binary patch execution, the smaller binary code segment continues executing with a binary instruction immediately following the branch instruction.

Abstract: The present invention manages memory buffers in a computer network system. In one embodiment, a managing system on a thin client unit modifies an amount of central processing unit (CPU) resource on the thin client unit that is granted to a server application (e.g., a X server application). The modification is based on a function of how many network information packets are in a packet queue of the thin client unit. By dropping the amount of CPU resource granted lower and lower as the queue gets more and more full, the server application reduces the rate at which it sends commands, thus giving the thin client unit the opportunity to catch up in processing the commands already in the queue. When the number of packets in the queue passes a high critical threshold, the granted CPU resource is dropped to zero, effectively shutting off the server application.

Abstract: A method and system of deflecting air circulated in a data center room are disclosed. A method for controlling air circulation within a room having an aisle between racks with computer systems mounted thereon comprises supplying cooling air to computer systems in the racks via holes in a floor of the room and using a deflector to reduce flow of cooling air along the aisle toward an air intake of a cooling unit without passing the computer systems.

Abstract: A heat sink uses a pump assembly to generate a magnetic field. Flow directions of electrically and thermally conductive liquid flowing through multiple pipes that go through the pump assembly are dependent on an orientation of the magnetic field and/or the direction of electrical current induced across flowing fluid in the magnetic field. In such a manner, cool liquid may be directed toward a heat source and warmer liquid may be directed to flow away from the heat source, where heat transfer occurs between the liquid and the heat sink. Additional pump assemblies that generate separate magnetic fields may be used to increase fluid flow volume, thereby increasing heat transfer away from the heat source.

Abstract: A network collaboration system facilitates collaborations between network clients having access to a digital network. The system uses audio mixes to provide different levels of voice conferences between the meeting participants. When a virtual meeting space is created, each meeting participant is given certain access privileges. In a main collaboration, those participating in the main collaboration receive an audio output that includes audio inputs from the other participants. A separate group of participants may be sequestered in a waiting room, unable to receive audio inputs from participants in the main collaboration. Certain participants in the main collaboration have the ability to grant access to the waiting room participants to join the main meeting, depending on the access privileges of the participant granting access. Main collaboration participants may also exit the main collaboration and enter the waiting room.

Abstract: A computer-based method for generating a Web service. The method includes identifying first and second service components for inclusion in the Web service, which includes locating available services using service detectors that use differing search techniques and displaying the located services to the user to allow the user to make a selection to identify the first and second service components. The method continues with generating a description or contract for the Web service defining service behavior including invoking rules. A transport structure is then created for accessing the new Web service such as a transmission envelope. The Web service is advertised as being available on the communications network including registering the Web service with a services registry linked to the communications network.

Abstract: Methods and systems thereof for providing security of information in a computer system are described. The information is received in the user space defined according to the operating system executed by the computer system. An encode system call is used to copy the information to the kernel space defined according to the operating system. The information may also be encrypted in response to the encode system call. The information can then be cleared from user space. A decode system call causes the information to be returned to user space. If the information is encrypted, the information is also decoded in response to the decode system call. As a result, the amount of time that the information is accessible outside of kernel space is reduced.
