摘要： A method of converting an original code sequence to a modified code sequence where the original code sequence includes a procedure call that is prior to a load instruction to one of a first plurality of registers is provided. The method includes inserting the load instruction into the modified code sequence and inserting the procedure call into the modified code sequence subsequent to the load instruction. The method further includes inserting an advanced load instruction to one of a second plurality of registers into the modified code sequence prior to the procedure call and inserting a checking instruction associated with the advanced load instruction into the modified code sequence subsequent to the procedure call.

摘要： Atomic sixteen-byte memory accesses are provided in a 64-bit system in which eight of the bytes are stored in a 64-bit general-purpose register and eight of the bytes are stored in a 64-bit special-purpose register. A 16-byte load instruction transfers the low eight bytes to an explicitly specified general-purpose register, while the high eight bytes are transferred to the special-purpose register. Likewise, a 16-byte store instruction transfers data from a general-purpose register and the special-purpose register. Also provided is an 8-byte compare conditioning a 16-byte exchange semaphore instruction that can be used to accelerate algorithms that use multiple processors to simultaneously read and update large databases.

摘要： An event calling for a migration of a workload from a source processor set of processing units to a target processor set of processing units is detected. Processes of the workload are allocated to a second processor set of processing units so that some workload processes are executed on the source processor set and some workload processes are executed on a second processor set of processor units. Then, some workload processes are allocated to the second processor set so that no workload process is executing on the source processor set and at least some of said processes are executing on the second process set. The second processor set can be the target processor set or an intermediate processor set from which the workload is migrated to the target processor set.

摘要： A secure promotion mechanism promotes a current privilege level of a processor in a computer system. The current privilege level controls application instruction execution in the computer system by controlling accessibility to system resources. An operating system performs a privilege promotion instruction, which is stored in a first page of memory not writeable by an application instructions at a first privilege level. The privilege promotion instruction reads a stored previous privilege level state, compares the read previous privilege level state to the current privilege level, and if the previous privilege level state is equal to or less privileged than the current privilege level, promotes the current privilege level to a second privilege level which is higher than the first privilege level.

摘要： A chassis is configured to hold at least one horizontal row of node modules and a fabric module. The fabric module can be positioned above or below the row so that it can communicatively couple two or more node modules. Each of the node modules and the fabric modules can be inserted into and removed from the chassis longitudinally.

摘要： A multiprocessor computer system comprises multiple data processors, each with an internal clock for providing time stamps to application software. The processors take turns as synchronization masters. The present master transmits a “request” time stamp (indicating the time of transmission according to the local clock) to the other (“slave”) processors. Each slave processor responds by returning a “response” time stamp (indicating the time of transmission of the response according to the local slave clock) of its own along with the received request time stamp. The master calculates clock adjustment values from the time of receipt of the responses and the included time stamps. This allows asynchronous clocks to be synchronized so that application time stamps can be validly compared across processors.

摘要： A processor comprising a feature indicator associated with at least one of a first sequence of one or more instructions, a first register, a second register, and an execution core is provided. The execution core is configured to execute a second instruction to cause the first register to be set to a first value using the feature indicator and to cause the second register to be set to a second value using the feature indicator. The execution core is configured to execute the first sequence of one or more instructions to cause a function to be performed in response to the first value in the first register indicating a true condition, and the execution core is configured to execute a second sequence of one or more instructions to cause the function to be performed in response to the second value in the second register indicating the true condition.

摘要： A computer system includes physical registers holding data for compiled programs and a portion of the physical registers form a register stack which wraps around when full. An N-bit current wraparound count state tracks physical register remapping events which cause the register stack to wraparound or unwrap. An advanced load address table (ALAT) has entries corresponding to load instructions, each entry has at least one memory range field defining a range of memory locations accessed by a corresponding load instruction, a physical register number field corresponding to a physical register accessed in the corresponding load instruction, and an N-bit register wraparound field which corresponds to the N-bit current wraparound count state for the corresponding load instruction. A check instruction accesses the ALAT to determine whether a store instruction and an advanced load instruction, which is scheduled before the store instruction, potentially accessed a common memory location. After the execution of the store instruction, an absence of an entry corresponding to the load instruction in the ALAT indicates that a common memory location may have been accessed by the store and load instructions.

摘要： A method and apparatus for controlling groups of registers includes a pluity of registers of the same type logically separated into a plurality of groups and a plurality of indicators corresponding to the plurality of groups of registers, each of the plurality of indicators identifying whether a corresponding group of registers has been modified by a task currently being executed by the processor. A control logic is also included, coupled to the plurality of registers, to selectively control the plurality of registers by group based at least in part on the plurality of indicators.
