High speed microtribology with quartz crystal resonators.
Quartz resonators in contact with metal-covered spheres have been used to study the tribology of micron-sized metal-metal contacts at high speed (1 m/sec and high frequency (12 MHz), while maintaining a shear amplitude in the nanometer range. The data aquisition is based on ring-down experiments, where the electrical excitation is periodically interrupted and the free decay of the oscillation i...
متن کاملEfficient Memory Mapped File I/O for In-Memory File Systems
Recently, with the emergence of low-latency NVM storage, software overhead has become a greater bottleneck than storage latency, and memory mapped file I/O has gained attention as a means to avoid software overhead. However, according to our analysis, memory mapped file I/O incurs a significant amount of additional overhead. To utilize memory mapped file I/O to its true potential, such overhead...
متن کاملA Flash-Memory Based File System
A flash memory device driver that supports a conventional UNIX file system transparently was designed. To avoid the limitations due to flash memory's restricted number of write cycles and its inability to be overwritten, this driver writes data to the flash memory system sequentially as a Log-structured File System (LFS) does and uses a cleaner to collect valid data blocks and reclaim invalid o...
متن کاملSupporting File Operations in Transactional Memory
Researchers have proposed transactional memory as a concurrency primitive to simplify the development of multithreaded programs. In this paper we present a new approach for supporting I/O operations in the context of transactional memory. Our approach provides isolation between the file operations of different transactions while allowing multiple transactions to concurrently perform I/O. To eas...
متن کاملIntegrating file operations into transactional memory
Researchers have proposed transactional memory as a concurrency primitive to simplify the development of multithreaded programs. In this paper we present a new approach for supporting I/O operations in the context of transactional memory. Our approach provides isolation between the file operations of different transactions while allowing multiple transactions to concurrently perform I/O. To eas...
