Modify the cache code (H5C) to support automatic cache resizing to adapt to the work load at run time. Description: Different applications require different sized caches to maintain an acceptable hit rate. This set of changes attempts to provide the ability to adjust to circumstances automatically. Solution: Added highly configurable code to allow the user to either set a fixed cache size, or allow the cache to grow and shrink according to conditions. If enabled, cache size increases are triggered when the hit rate drops below a user specified threshold in a user specified interval. Cache size reductions (if enabled) are triggered when either the hit rate exceeds some user specified threshold over a user specified interval, when the cache contains "enough" entries that haven't been accessed for a user specified interval, or some mix of the above. See the header comments on the H5C_auto_size_ctl_t structure in H5Cprivate.h for further details. At present, the cache resize configuration options are not accessible via the user API. Must add this. Platforms tested: h5committested, heping (serial), and copper (parallel) Misc. update: |
