* Fri Dec 21 2018 Christopher M. Cantalupo <[email protected]> v1.0.0-rc1
- Release overview:
- This is the first candidate for the v1.0.0 release of the GEOPM package.
- The version 1.0 is significant in that semantic versioning https://semver.org/ is intended for all subsequent releases.
- The APIs defined by all installed header files and the documented behavior of those interfaces shall remain compatible with linking applications until version 2.0.
- The documented definition for all built in signals and controls supported by PlatformIO is not intended to change prior to version 2.0.
- Expected changes prior to v1.0.0 release:
- The documentation included in this release candidate will be improved upon prior to the actual v1.0.0 release.
- Man pages which currently link to doxygen will be filled in.
- The definition of the high order bits in the REGION_ID# signal supported by PlatformIO may be changed in the way documented in the PlatformIO(3) man page to split into two signals (REGION_ID AND REGION_HINT).
- It is possible that interface classes currently prefixed with "I" may be renamed to exclude the "I" (e.g. IPlatformIO -> PlatformIO).
- In this case the concrete implementation would be appended with "Imp" (e.g. PlatformIO -> PlatformIOImp).
- The appearance of the epoch signal in the REGION_ID column of the trace will be removed.
- The EPOCH_COUNT signal will be added to the default set of traced signals to enable tracking of epoch calls.
- High level summary of changes since v0.6.1:

- These have been replaced by the PlatformIO / IOGroup / Agent class interactions.
- The Kontroller object which was supporting the new code path has been renamed Controller.

- GEOPM no longer depends on the hwloc library, and is relying on running lscpu on compute node instead.
- Modified implementations and interfaces:
