摘要： Providing for multi-tiered RAM control is provided herein. As an example, a RAM access management system can include multiple input controllers each having a request buffer and request scheduler. Furthermore, a request buffer associated with a controller can vary in size with respect to other buffers. Additionally, request schedulers can vary in complexity and can be optimized at least for a particular request buffer size. As a further example, a first controller can have a large memory buffer and simple scheduling algorithm optimized for scalability. A second controller can have a small memory buffer and a complex scheduler, optimized for efficiency and high RAM performance. Generally, RAM management systems described herein can increase memory system scalability for multi-core parallel processing devices while providing an efficient and high bandwidth RAM interface.

摘要： Architecture for a multi-threaded system that applies fairness to thread memory request scheduling such that access to the shared memory is fair among different threads and applications. A fairness scheduling algorithm provides fair memory access to different threads in multi-core systems, thereby avoiding unfair treatment of individual threads, thread starvation, and performance loss caused by a memory performance hog (MPH) application. The thread slowdown is determined by considering the thread's inherent memory-access characteristics, computed as the ratio of the real latency that the thread experiences and the latency (ideal latency) that the thread would have experienced if it had run as the only thread in the same system. The highest and lowest slowdown values are then used to generate an unfairness parameter which when compared to a threshold value provides a measure of fairness/unfairness currently occurring in the request scheduling process. The architecture provides a balance between fairness and throughput.

摘要： Some implementations provide techniques and arrangements for distance measurements between computing devices. Some examples determine a distance between devices based at least in part on a propagation time of audio tones between the devices. Further, some examples determine the arrival time of the audio tones by performing autocorrelation on streaming data corresponding to recorded sound to determine a timing of an autocorrelation peak indicative of a detection of an audio tone in the streaming data. In some cases, cross correlation may be performed on the streaming data in a search window to determine a timing of a cross correlation peak indicative of the detection of the audio tone in the streaming data. The location of the search window in time may be determined based at least in part on the timing of the detected autocorrelation peak.

摘要： The subject disclosure relates to a method and apparatus for routing data in a network-based computer game via proxy computers. The method and system includes a set of techniques that utilizes the proxy computers to thwart traffic analysis in high-speed games while continuing to satisfy the games' latency requirements. The method and apparatus facilitates thwarting multiple classes of traffic analysis, including inspection of unencrypted header fields, observation of packet size, correlation of packet timing, and collusion among players. A matchmaking system for matching players in a network-based computer game in a manner that resists traffic analysis is also provided.

摘要： In a participatory system, a reward is distributed to participants based on their contributions to the system and the contributions of direct and indirect referrals of the participant (descendant referrals). A convex function is applied to the effective contribution of each participant to determine the weighted contribution of the participant, and the participant's reward is based on the participant's weighted contribution less the weighted contributions of child participants referred by the participant.

摘要： The described implementations relate to collaborative speed determination in distributed systems. One method estimates upload speeds of a plurality of hosts. The method sends a first bandwidth probe from a first host to a second host. The method receives, at the first host, a second bandwidth probe sent from the second host. The method determines which of the first and second bandwidth probes was relatively slower. The method designates either of the first or second hosts that sent the relatively slower bandwidth probe as a loser and takes a speed of the bandwidth probe of the loser as a first estimate of the loser's upload speed.

摘要： Power management functionality is described for implementing an application in an energy-efficient manner, without substantially degrading overall performance of the application. The functionality operates by identifying at least first data and second data associated with the application. The first data is considered to have a greater potential impact on performance of the application compared to the second data. The functionality then instructs a first set of hardware-level resources to handle the first data and a second set of hardware-level resources to handle the second data. The first set of hardware-level resources has a higher reliability compared to the second set of hardware-level resources. In one case, the first and second hardware-level resources comprise DRAM memory units. Here, the first set of hardware-level resources achieves greater reliability than the second set of hardware-level resources by being refreshed at a higher rate than the second set of hardware-level resources.

摘要： Dynamically replicated memory is usable to allocate new memory space from failed memory pages by pairing compatible failed memory pages to reuse otherwise unusable failed memory pages. Dynamically replicating memory involves detecting and recording memory faults, reclaiming failed memory pages for later use, recovering from detected memory faults, and scheduling access to replicated memory pages.
