| 요약 | Fast non-volatile memories (NVMs) are appearing on the processor memory bus alongside DRAM, becoming non-volatile main memories (NVMMs). The resulting hybrid memory systems will provide software with low-latency, high-bandwidth access to persist |
| 요약 | This thesis first presents NOVA, a log-structured file system designed to maximize performance on hybrid memory systems while providing strong consistency guarantees. NOVA adapts conventional log-structured file system techniques to exploit the |
| 요약 | NOVA excels in metadata-intensive and write-intensive workloads. Experimental results show that NOVA provides 22% to 216x throughput improvement compared to state-of-the-art file systems, and 3.1x to 13.5x improvement compared to file systems th |
| 요약 | NVMM has different failure models from disks and SSDs. Disk I/O errors are not vital for the operating system, but memory errors can hang the entire OS. Persistent memory makes the issue worse: the error is durable and system reboot cannot remov |
| 요약 | Finally, the thesis evaluates existing applications and analyzes their access patterns to the file system. It finds out that existing NVMM file systems such as ext4-DAX and xfs-DAX do not perform well under applications' typical access patterns, |
