-* Refine key abstractions and their definition
+We talked about breaking the runtime into a set of services that need to be available to the applications codes both explicitly and implicitly. These services can be placed anywhere in the system and accessible to any node in the system either directly or through communication with a node that supports that service.
-* Using refined key abstractions, define runtime services
+==== Runtime Services ====
-* Create a matrix for mapping on what current investments (including Charm++ runtime) provide these services and a brief description on how the services are provided.
+All the services can have a runtime, just in time or ahead of time component. We could write up what these behaviors are  under each service
