Fri Dec 21 2018 Christopher M. Cantalupo christopher.m.cantalupo@intel.com 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:
With this release we have removed all references to the Policy, Decider, Platform and PlatformImp objects.
These have been replaced by the PlatformIO / IOGroup / Agent class interactions.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.
The legacy Controller implementation has been removed.
GEOPM no longer depends on the hwloc library, and is relying on running lscpu on compute node instead.
Modified implementations and interfaces:
Rename launcher to geopmlaunch.
Do not install geopmanalysis and geopmplotter command line utilities.
The command line interfaces for these tools will be changing.
Once they are committed, we will begin installing them again.
Remove unused error codes from geopm_error.h.
Remove some deprecated interfaces and files.
Remove legacy artifacts from Reporter and Tracer.
Remove legacy structures from geopm_message.h.
Remove deprecated API headers.
Remove CtlConf Python object.
Remove region ID memory from derivative for power signals, this is a feature for agent to implement.
Remove unused arguments from the geopmctl_main.
Remove push_combined_signal() from PlatformIO interface.
Remove NAN check for policy in Controller. Agents are responsible for handling NAN.
Remove IPlatformTopo::define_cpu_group(). This method is not implemented and not used.
Remove MPI bit from region ID in report.
Remove install of geopm_message.h and geopm_plugin.h.
Remove environment variables for min/max frequency used by EnergyEfficientAgent: this functionality is provided through the policy as documented.
Fixes for online mode of EnergyEfficientAgent: ignore 0.0 when sampling runtime, fix min/max frequency range in analysis.py, fix final requested frequency printed in report.
EnergyEfficientAgent no longer considers DRAM energy in its optimization.
Change default frequency for hints from min to max in EnergyEfficientAgent.
Implement EnergyEfficientAgent analysis using hints only.
Change meaning of EPOCH_RUNTIME signal: MPI and ignore time reported explicitly and a separately.
Install many C++ headers into /usr/include/geopm.
Move geopmbench source files files from tutorial directory into src.
Don't copy any files from src into tutorials.
Update tutorials to use Agent code path.
Throw if multiple hints given to geopm_prof_region.
Allow writing controls for containing domains: the same value will be written to every subdomain.
Update EpochRuntimeRegulator accounting: PKG and DRAM energy dissociated from rank.

GEOPM beta release!
Community updates:
New landing page https://geopm.github.io
New Slack channel https://geopm.slack.com
New Code of Conduct
New pull request template
Contributing instructions updated with details of gerrit review process.
Modified implementations and interfaces:
Major refactor of the controller and plugin architecture is provided as an optional new code path.
Most of the changes made to the implementation for this release modify the new code path.
The old code path is still available for users as long as the controller is run without the GEOPM_AGENT environment variable set.
The new code path will be active if the user selects an agent by name with the GEOPM_AGENT environment variable when launching the controller.
The old code path is maintained in the current Controller object along with the the Decider / Platform / PlatformImp plugins.
The new code path is maintained in a replacement for the Controller which has been temporarily named the Kontroller.
The Kontroller will be renamed the Controller after this release, and the old code path will no longer be available.
Similar to the Kontroller/Controller replacement, the KprofileIOGroup KprofileIOSample and KruntimeRegulator are temporary replacements for their non-K counterparts and will be renamed.
The beta release enables a new set of plugin interfaces named the IOGroup, Agent, and Comm.
It is through the IOGroup, Agent and Comm plugins that the GEOPM runtime can be extended.
The Decider / Platform / PlatformImp plugin extensions are deprecated and will be removed after this release.
The IOGroup plugin enables a user to add new signal and control mechanisms for an Agent to read and write.
The Agent plugin enables a user to add new monitor and control algorithms to the GEOPM runtime.
MPI use by the GEOPM runtime which is not linked by application has been completely encapsulated in the Comm object.
The tutorial has been extended with two new directories: tutorial/agent and tutorial/iogroup.
The tutorial/iogroup directory documents how to write an IOGroup plugin.
The tutorial/agent directory documents how to write an Agent plugin.
The interface to the resource manager has been made much more flexible for supporting the new Agent interfaces.
The resource manager interface is documented in the geopm_agent_c(3) and geopm_endpoint_c(3) man pages.
Additionally command line tools have been proposed and partially implemented to support the interfaces documented in those man pages.
The geopm_agent_c(3) APIs and geopmagent(1) CLI has software support.
The endpoint interfaces are a work in progress that has not yet been integrated into the mainline source.
The PlatformIO object provides the interface to the IOGroups.
The PlatformIO C++ object will soon have an associated C interface documented as geopm_platformio_c(3).
The geopmread and geopmwrite provide a CLI to the PlatformIO features.
Introducing the MSRIOGroup which provides an implementation of the IOGroup for MSRs.
Introducing the TimeIOGroup which provides an IOGroup for the time signal.
Introducing the CpuinfoIOGroup which provides data from /proc/cpuinfo as signals.
Introducing the ProfileIOGroup which provides profile data collected from the main compute application through the geopm_prof_c(3) APIs.
The release includes three new installed binaries: geopmread, geopmwrite, and geopmagent.
Each of these command line interfaces is documented with a man page and there is a man page for a future command line tool called geopmendpoint.
Deprecated geopm_policy_() interfaces that have been replaced with the geopm_agent_() and geopm_endpoint_*() APIs.
Introducing the first three Agent implementations: MonitorAgent, PowerBalancerAgent, and EnergyEfficientAgent.
Introducing PlatformTopo, replacement for PlatformTopology.
Introducing DefaultProfile singleton which supports geopm_prof_c(3) APIs for profiling.
Added documentation for monitor, energy_efficient, and power_balancer Agents, but the implementation is not currently aligned.
The monitor agent is implemented and fully featured.
The energy_efficient agent will soon be extended to match the man page, and currently use of the network is not enabled.
The existing implementation of the energy_efficient agent does currently provide similar functionality to the efficient_freq Decider.
The power_balancer agent is a work in progress that is not well aligned with the man page, but will be feature complete soon.
Reports and traces generated by Agent code path are designed to be backward compatible with reports and traces generated with the Decider code path.
New environment variables documented in geopm(7): GEOPM_ENDPOINT, GEOPM_AGENT, GEOPM_TRACE_SIGNALS, and GEOPM_DISABLE_HYPERTHREADS.
Remove GEOPM_ERROR_AFFINITY_IGNORE environment variable, no longer required for testing.
New plugin registration mechanism has been put in place and new factory has been implemented.
Replace independent factories with single templated class the PluginFactory.
No longer register a plugin using a half instantiated object.
Removed call to dlsym, and plugins now use attribute((constructor)) to specify a callback target used when plugin is loaded.
In this callback the plugin should register with its respective factory.
Each plugin type has a make_plugin() static method that creates the plugin object and returns a pointer to the base class.
The make_plugin() function pointer is what is registered with the factory.
Extend the PluginFactory to require a the registration of a dictionary (map<string,string>) to enable queries of plugin capabilities.
Use stricter criterion for selecting plugin files to load, name must be of the form libgeopmpi*.so.0.0.0 where 0.0.0 is the GEOPM ABI version.
Moved geopm_plugin_description_s definition to geopm.h.
Add a configure option to enable use of the msr-safe ioctl interface for writing with PlatformIO.
The msr-safe ioctl interface should not be used for writing unless the system has an msr-safe installation that has fixed LLNL/msr-safe#38.
Added APIs for manipulating hint bits in region id hash.
Many changes were made to modernize the use of C++.

Standardize the IOGroup signal and control names so that they are prefixed by the IOGroup name and two colons.
Agents should generally use high level aliases rather than these low level signals and controls.
Introduce functions for converting between signals and bit-fields to allow for PlatformIO to provide full 64 bit integer signals like the region ID.
Add overflow function type to MSR class.
Change frequency APIs to use Hz to enforce uniform use of SI units.
Use instruction offset in OMPT derived region name; this resolves a name ambiguity when more than one OpenMP region is discovered within the same function.
Use gmock archive uploaded to the geopm organization on github.
PlatformTopo is built on top of lscpu and does not require hwloc.
Throw on GlobalPolicy misconfiguration earlier in the runtime execution.
Rename SimpleFreqDecider to EfficientFreqDecider which will be replaced by EnergyEfficientAgent.
Update to efficient Decider and Agent related environment variables according to above name changes.
The json-c library is no longer a dependency, all references have been removed.
