source: XIOS/trunk/src/transformation/axis_algorithm_transformation.hpp @ 829

Last change on this file since 829 was 829, checked in by mhnguyen, 8 years ago

Refactoring transformation code

+) On exchanging information during transformation, not only global index are sent but also local index
+) Correct a bug in distributed hash table (dht)
+) Add new type for dht
+) Clean up some redundant codes

Test
+) On Curie
+) Every test passes
+) Code runs faster in some cases (up to 30%)
