Software Activation Using Multithreading

Software Activation Using Multithreading

Software activation is an anti-piracy technology designed to verify that software products have been legitimately licensed. Activation should be quick and simple while simultaneously being secure and protecting customer privacy. The most common form of software activation is for the user to enter a legitimate product serial number. However, software activation based on serial numbers appears to...

Software-Controlled Multithreading Using Informing Memory Operations

Memory latency is becoming an increasingly important performance bottleneck, especially in multiprocessors. One technique for tolerating memory latency is multithreading, whereby we switch between threads upon expensive cache misses. In contrast with previous work on multithreading, we explore a new approach that is software-controlled rather than hardware-controlled. To implement software-cont...

Using Software-extended Architectures for Software Simultaneous Multithreading

A software-extended architecture (SEA) enhances a hardware architecture by placing a high-performance dynamic instruction-set translator between the application binary and the processor, improving processor utilization and enabling new functionality with no changes to either the processor or the binaries. Our prototype implementation of a software-extended Alpha 21164 can provide new system fun...

Using Multicast and Multithreading to Reduce Communication in Software DSM Systems

This paper examines the performance benefits of employing multicast communication and application-level multithreading in the Brazos software distributed shared memory (DSM) system. Application-level multithreading in Brazos allows programs to transparently take advantage of available local multiprocessing. Brazos uses multicast communication to reduce the number of consistency-related messages...
