Also included is a fix to the attribute problem for singletons.
Short explanation:
The prior system placed triggers and subscriptions on the registry for each process - approximately eight/process. Each of these had to be checked every time there was a registry operation such as a "put" or "increment-value". For large numbers of processes, this repetitive checking consumed some significant time.
The new system allows processes to "attach" to existing triggers and subscriptions, without creating a new one. Thus, there are now only eight triggers and five subscriptions on a job - *regardless of how many processes are being run*. This means that the registry now takes the same amount of time (which is pretty darn short) to process an operation regardless of how many processes are in a job.
I'll provide some startup times from scalability tests shortly - need to complete the commit so I can move the system to an appropriate cluster.
This commit was SVN r6164.
1. Added pid_t to the dps
2. Processes now "register" their local pid and update their location (i.e., nodename) on the registry during mpi_init
3. Added a new error code for values that exceed maximum for their data type (useful when transitioning a value from one variable to another of different size)
4. Fixed a few places where size_t was being incorrectly handled
5. Updated dps_test to cover pid_t types
This should now provide support for TotalView connection - which David is pursuing.
This commit was SVN r5623.
1. *correctly* fix the printing of size_t variables. Need to do this through a #define, not just typecast things. Thanks to Jeff/Brian for suggesting a cleaner way to do it (as opposed to just doing the #define at the print location). Note that not ALL of the prints have been "fixed" yet - will continue to identify them.
2. Add int64 and size_t to the pack/unpack unit tests.
3. Fix a bug in the int64 pack/unpack system.
