摘要： A computer readable medium that includes computer readable program code embodied therein. The computer readable medium causes the computer system to receive, by a data link rule enforcer, a packet from a packet source of the packets, and obtain a data link rule applying to a data link. The data link is operatively connected to the packet source, and the data link is associated with a media access control (MAC) address. The computer readable medium further causes the computer system to determine, by the data link rule enforcer, whether the packet complies with the data link rule, and drop, by the data link rule enforcer, the packet when the packet fails to comply with the data link rule.

摘要： A computer readable storage medium including executable instructions for heuristics-based task scheduling. Instructions include receiving a first event notification associated with a first event, where the first event is determined from the first event notification. Instructions further include determining whether a predicate for an action is satisfied by the first event, where the action predicate, the action, and an action parameter are associated with a task object in a task pool. Instructions further include obtaining the action parameter when the action predicate is satisfied by the first event, where a priority is assigned using a heuristics policy to the task object based on the action parameter. Instructions further include inserting the task object into a task queue using the assigned priority. The action associated with the task object is performed by an execution thread. The performance of the action is a second event associated with a second event notification.

摘要： One embodiment provides a system that facilitates the execution of a transaction for a program in a hardware-supported transactional memory system. During operation, the system records a misspeculation indicator of the transaction during execution of the transaction using hardware transactional memory mechanisms. Next, the system detects a transaction failure associated with the transaction. Finally, the system provides the recorded misspeculation indicator to the program to facilitate a response to the transaction failure by the program.

摘要： Some embodiments provide a system to assure enhanced security, e.g., by assuring that information is not revealed over a covert channel. All communications between a source system and a destination system may pass through an intermediate system. In some embodiments, the intermediate system may perform an additional level of blinding to ensure that the source system does not covertly reveal information to the destination system. In some embodiments, the intermediate system may request the source system to perform a modification operation, and then check if the source system performed the modification operation. Examples of the modification operation include a blinding operation and a cryptographic hashing operation.

摘要： Some embodiments of the present invention provide a processor, which includes a set of general-purpose registers and at least one execution unit. Each general-purpose register in the set of general-purpose registers is at least 64 bits wide, and the execution unit supports one or more Data Encryption Standard (DES) instructions. Specifically, the execution unit may support a permutation-rotation instruction for performing DES permutation operations and DES rotation operations. The execution unit may also support a round instruction to perform a DES round operation. Since the DES instructions use general-purpose registers instead of special-purpose registers to perform DES-specific operations, the processor's circuit complexity and area are reduced. Furthermore, in some embodiments, since the DES instructions require at most two operands, the number of bits required to specify the location of the operands are reduced, thereby enabling a larger number of instructions to be supported by the processor.
摘要翻译：本发明的一些实施例提供一种处理器，其包括一组通用寄存器和至少一个执行单元。通用寄存器组中的每个通用寄存器至少为64位宽，执行单元支持一个或多个数据加密标准（DES）指令。具体地，执行单元可以支持用于执行DES置换操作和DES旋转操作的置换旋转指令。执行单元还可以支持执行DES循环操作的循环指令。由于DES指令使用通用寄存器而不是专用寄存器来执行DES特定操作，所以处理器的电路复杂度和面积减少。此外，在一些实施例中，由于DES指令需要至多两个操作数，所以指定操作数的位置所需的位数减少，从而使更多数量的指令由处理器支持。

摘要： Some embodiments of the present invention provide a system for packet classification and spreading in a virtualized system. The system can use information in a packet's header to determine a destination system-image in the virtualized system, and a packet-spreading policy for the destination system-image. The system can determine a key using the information in a packet's header. Alternatively, the system can hash the information in the packet's header to obtain an index value. Next, the system can use the key or the index value to perform a lookup in a table which associates keys or index values with system images and/or packet-spreading policies. Once the destination system-image and the packet-spreading policy are determined, the system can deliver the packet to a thread on the destination system-image according to the packet-spreading policy.

摘要： A compilation method is provided for correcting compiler errors that include compiler internal errors and errors produced by running a validation suite. The method includes running a compiler on a computer and storing a set of optimization levels in memory accessible by the compiler. The method includes receiving a source file with the compiler that includes a user-defined optimization level to be used in compiling the source file. The method includes identifying a set of functions within the source file and using compiler components to compile these functions using the original optimization level. When the compiling results in an internal error occurring and being reported for one or more of the functions, the method includes using an optimization adjustment module to process the internal error and assign an adjusted or lower optimization level to the one or more functions and recompiling of these functions again with the lower optimization level.
