3 Changes between OASIS3-MCT_3.0 and OASIS3-MCT_2.0

The main evolution of OASIS3-MCT_3.0 with respect to OASIS3-MCT_2.0 is the support of coupling exchanges between parallel components deployed in much more diverse configurations than before, for example, within one same executable between components running concurrently on separate sets of tasks or between components running sequentially on overlapping sets of tasks. All details are provided in section 2.1.

This new version also includes:

• memory and performance upgrades
• a new LUCIA tool for load balancing analysis
• new memory tracking tool (gilt)
• improved error checking and error messages
• doxygen documentation
• expanded test cases and testing automation
• testing at high resolution (> 1M gridpoints), high processor counts (32k pes), and with large variable counts (> 1k coupling fields)
• many bug fixes
