  • System and method for performing incremental initialization of a master runtime system process
    Patent number: 7343603
    Abstract: A system and method for performing incremental initialization of a master runtime system process is presented. A set of one or more warmup actions is defined from a source definition provided as object-oriented program code. A master runtime system process is executed. Each warmup action is executed to refine a memory space of the master runtime system process. The memory space is cloned as a child runtime system process responsive to a process request and the child runtime system process is executed. Initialization is incremental, such that the warmup actions are interleaved with potential requests for cloning child runtime system processes. The interleaving allows a user to interact with the master runtime system process before the full set of warmup actions are completed by the master runtime system process.

  • System and method for interleaving infiniband sends and RDMA read responses in a single receive queue
    Patent number: 7342934
    Abstract: A system and method for processing interleaved Sends of encapsulated communications and responses to RDMA Reads in a single InfiniBand queue pair receive queue. The queue is implemented as one or more linked lists of memory buckets, and stores Send commands (containing encapsulated communications or RDMA Read descriptors for retrieving a communication) until their associated communications are assembled and forwarded to a transmit module. The queue grows as new InfiniBand packets are received, and shrinks as communications (e.g., Ethernet packets) are forwarded. A next packet pointer identifies the next Send command whose communication should be assembled. If it is an encapsulated communication, the communication is forwarded. Otherwise, RDMA Read requests are issued and the responses bypass the tail of the queue and are assembled in an assembly area at the head of the queue.

  • Efficient read after write bypass
    Patent number: 7343477
    Abstract: Predicting address matches between a read type operation and a write type operation based on address representations allows for efficient RAW bypass. The spatial locality characteristic of code allows for address match prediction with address representations that are smaller than the actual addresses, thus allowing for faster comparison. Operations for performing the RAW bypass commence upon predicting an address match. While these operations are being performed, other operations for verifying the prediction are performed. If the address match prediction is verified, then the RAW bypass has been performed without hindrance. If the address match is proved incorrect, then the corresponding read type operation is reissued and/or re-executed.

  • Method and apparatus for achieving fair cache sharing on multi-threaded chip multiprocessors
    Publication number: 20080059712
    Abstract: In a computer system with a multi-core processor having a shared cache memory level, an operating system scheduler adjusts the CPU latency of a thread running on one of the cores to be equal to the fair CPU latency which that thread would experience when the cache memory was equally shared by adjusting the CPU time quantum of the thread. In particular, during a reconnaissance time period, the operating system scheduler gathers information regarding the threads via conventional hardware counters and uses an analytical model to estimate a fair cache miss rate that the thread would experience if the cache memory was equally shared. During a subsequent calibration period, the operating system scheduler computes the fair CPU latency using runtime statistics and the previously computed fair cache miss rate value to determine the fair CPI value.

  • Updating profile frequency for procedure inlining
    Patent number: 7340732
    Abstract: A method and apparatus for frequency-updating for procedure inlining. The frequency-updating scheme assumes the call graph of a program has no cycles. It keeps the frequency for each procedure as accurate as that before inlining. Using the present invention, the runtime performance of a source program by a compiler is improved. A source program is analyzed to generate a call graph of the source program, wherein each of the procedures has a first known execution frequency. The call graph is used in conjunction with inlining plans by an inlining algorithm to generate an inlined version of the source program wherein selected call sites have been inlines. An updated execution frequency is generated for each of the procedures and the updated execution frequency for each of the procedures is used to generate optimized executable code for the source program.

  • Value prediction for missing read operations instances
    Patent number: 7340567
    Abstract: Typically, missing read operations instances account for a small fraction of the operations instances of an application, but for nearly all of the performance degradation due to access latency. Hence, a small predictor structure maintains sufficient information for performing value prediction for the small fraction of operations (the missing instances of read operations) that account for nearly all of the access latency performance degradation. With such a small predictor structure, a processor value predicts for selective instances of read operations, those selective instances being read operations that are unavailable in a first memory (e.g., those instances of read operations that miss in L2 cache). Respective actual values for prior missing instances of the read operations are stored and used for value predictions of respective subsequent instances of the read operations.
