ACM SIGOPS Operating Systems Review
Preserved Fulltext
A study has been done analyzing the effect of decreased memory size on disk activity and based on the study, a threshold based policy is proposed which is found to settle in the operating point for a simple ...
Based on the profiled information, the BOS daemon decides about powering down/up chips. Powering down is emulated within the kernel using mechanisms such as page migration and invisible buddy. ...

The algorithms respond in an online manner to maintain a dynamically changing working set of disk-resident files, while providing a guaranteed degree of contiguity in the layout of each file on the device ...

Our current prototype file system incurs between a 1% and 6% overhead on the default native file system EXT3 for in-cache system workloads. ...
The modern file system is still implemented in the kernel, and is statically linked with other kernel components. ...
The buddy index acts like a buddy allocator tree, storing which blocks on the disk are free, and splitting or merging blocks as necessary. Actual blocks are allocated from the block store. ...

We compare the obtained results with theoretical expectations based on the bandwidth of participating disks. Mitra attains between 65% to 100% of the theoretical expectations. ...
First, the EVEREST file system allows different files (corresponding to objects of different media types) to be retrieved at different block size granularities. ...
The final approach, and the one used by Mitra, employs the buddy algorithm to approximate a contiguous layout of a file on the disk without wasting disk space. ...

Their storage subsystems are expected to be hierarchical, consisting of memory, magnetic disk drives, optical disk drives, and tape libraries. The database itself resides permanently on the tape. ...
Similarly, we have avoided file systems that support extent-based allocation (e.g., WiSS (Chou et al., 1985) ) because their design targets files that are allowed to grow and shrink dynamically; the objects ...
