Fast scalable deterministic consensus for crash failures
We study communication complexity of consensus in synchronous message-passing systems with processes prone to crashes. The goal in the consensus problem is to have all the nonfaul...

Impact of NVRAM write cache for file system metadata on I/O performance in embedded systems
File systems make use of part of DRAM as the buffer cache to enhance its performance in traditional systems. In this paper, we consider the use of Non-Volatile RAM (NVRAM) as a w...
