Detailed Description

Test

How the component of a process determines its trace output: the file name comes from the component name, and YAC_PAK_TRACE_STRIDE selects the writing ranks within the component. Both are only known at yac_cdef_comp. Must be run with 4 MPI ranks.

Tests 1-3 put "atm" on rank 0 and "ocn" on ranks 1-3. The sizes differ on purpose: with equal sizes the selection within the communicator and within the component coincide.

Tests:

1. YAC_PAK_TRACE_STRIDE=2: only the ranks selected within their component write and both write modes agree.
2. YAC_PAK_TRACE_STRIDE=1: nothing is filtered out.
3. Setup-only traces (YAC_PAK_TRACE_LEVEL=0) are named after the component, although no coupling event carries a component name.
4. A process defining two components of equal size picks the same one on all ranks, independent of the order it defined them in.
5. A process defining a subcomponent is attributed to the larger one.
