Abstract: One embodiment of the present invention provides a processor that supports multiple-issue execution. This processor includes a register file, which contains an array of memory cells, wherein the memory cells contain bits for architectural registers of the processor. The register file also includes multiple read ports and multiple write ports to support multiple-issue execution. During operation, if multiple read ports simultaneously read from a given register, the register file is configured to: read each bit of the given register out of the array of memory cells through a single bitline associated with the bit; and to use a driver located outside of the array of memory cells to drive the bit to the multiple read ports. In this way, each memory cell only has to drive a single bitline (instead of multiple bitlines) during a multiple-port read operation, thereby allowing memory cells to use smaller and more power-efficient drivers for read operations.

Abstract: A challenge string is sent from a server to an authentication card. The challenge string is encrypted using a private key on the authentication card. Then, the encrypted challenge string is sent as a response from the authentication card to the server. A unique identifier of the authentication card is correlated to a user record residing at the server to obtain an authentication certificate from within the user record. The authentication certificate includes a public key. The public key from the authentication certificate is used to decrypt the response at the server. A determination is then made as to whether the decrypted response matches the challenge string as originally sent from the server to the authentication card. If the decrypted response matches the original challenge string, the authentication is successful. Otherwise, the authentication fails.

Abstract: A method for identifying a degraded fan measures acoustic data from an operating datacenter fan. A motor rotation frequency and a vane passing frequency are determined from the acoustic data. Amplitudes of the frequencies are determined from the acoustic data. If the amplitude of the motor rotation frequency is greater than the amplitude of the vane passing frequency, then it is determined that the fan is degraded.

Abstract: Disclosed are systems and methods for reclaiming posted buffers during a direct memory access (DMA) operation executed by an input/output device (I/O device) in connection with data transfer across a network. During the data transfer, the I/O device may cancel a buffer provided by a device driver thereby relinquishing ownership of the buffer. A condition for the I/O device relinquishing ownership of a buffer may be provided by a distance vector that may be associated with the buffer. The distance vector may specify a maximum allowable distance between the buffer and a buffer that is currently fetched by the I/O device. Alternatively, a condition for the I/O device relinquishing ownership of a buffer may be provided by a timer. The timer may specify a maximum time that the I/O device may maintain ownership of a particular buffer. In other implementations, a mechanism is provided to force the I/O device to relinquish some or all of the buffers that it controls.

Abstract: Various embodiments herein include one or more of systems, methods, software, and/or data structures to implement a multi-way branch statement in a computer programming language. The multi-way branch statement may include a plurality of case labels each having a non-primitive data type (e.g., strings) and being associated with a block of code to be executed dependent upon a control variable that also has a non-primitive data type. The implementation may include encoding the case labels for the multi-way branch statement as a binary decision diagram (BDD), such as a zero-suppressed binary decision diagram (ZDD), wherein the control variable for the multi-way branch statement may be compared with the case labels by stepping through the BDD. The BDD may include identifiers that provide information regarding which of the case labels is matched by the control variable, such that an appropriate code block may be executed.

Abstract: During a method, a modulus circuit determines a modulus base p of a first number and a modulus base p of a second number. Also, the modulus circuit performs the operation using the modulus base p of the first number and the modulus base p of the second number, and calculates a modulus base p of the result of the operation involving the first number and the second number. Next, the modulus circuit compares the result of the operation carried out on the modulus base p of the first number and the modulus base p of the second number with the modulus base p of the operation performed on the first number and the second number to identify potential errors associated with the operation. Moreover, the modulus circuit repeats the method to identify additional potential errors associated with the operation, where the determining and calculating operations are repeated using moduli base q.

Abstract: A mechanism is disclosed for enabling a set of code intended to be executed on a first platform (intended platform) to be executed on another platform (target platform). In one implementation, this mechanism takes a significantly different approach than that taken by current techniques. Rather than duplicating, augmenting, or changing a platform to accommodate the set of code, this mechanism alters the set of code to accommodate the platform. By altering the set of code, the mechanism causes the set of code to compensate for the difference(s) between the intended platform and the target platform. By compensating for the difference(s) in the two platforms, the set of code, when executed on the target platform, is able to produce the same result or results as it would have produced had it been executed on the intended platform. Thus, the set of code is able to execute properly on the target platform.

The first processor node may include a first local arbiter, which may be configured to perform one or more of a memory node decode or a coherency check on the first local memory. The processor node may also include a switch coupled to the first local arbiter for enabling and/or disabling the first local arbiter. Thus one or more processor nodes may be coupled together in various distributed shared memory configurations, depending on the configuration of their respective switches.

Abstract: Techniques for handling dependency conditions, including evil twin conditions, are disclosed herein. An instruction may designate a source register comprising two portions. The source register may be a double-precision register and its two portions may be single-precision portions, each specified as destinations by two other single-precision instructions. Execution of these two single-precision instructions, especially on a register renaming machine, may result in the appropriate values for the two portions of the source register being stored in different physical locations, which can complicate execution of an instruction stream. In response to detecting a potential dependency, one or more instructions may be inserted in an instruction stream to enable the appropriate values to be stored within one physical double precision register, eliminating an actual or potential evil twin dependency.
