source: XIOS/trunk/src/server_distribution_description.hpp @ 657

Last change on this file since 657 was 657, checked in by mhnguyen, 7 years ago

Making changes in domain to make sure unstructed grid work with new method of index distribution

+) Change the way define i_index and j_index of a domain
+) Remove some redundant attributes of domain
+) Adjust the way to calculate index distribution on server side

Test
+) Make some minor change to test_unstruct_complete to work with new XIOS
+) On Curie
+) All test pass and correct
