Communicator List

Key:
-l [--communicators_list]
-E [--internal_communicators]
These reports provide information about all communicators used in the application. The reports are sorted by time to identify the most important communicator in the application.

Example 1: List of Communicators

To generate this report, run:
aps-report aps_result/--communicators_list
| Communicators used in the application |--------------------------------------------------------------------------------------------------------- | Communicator Id  Communicator Size   Time(Rank Average)(sec)       Ranks |---------------------------------------------------------------------------------------------------------          1                4                    6.51(1.63)           0,1,2,3 |---------------------------------------------------------------------------------------------------------          0                2                    3.52(1.76)             0,1 |---------------------------------------------------------------------------------------------------------

Example 2: List of Communicators with Internal IDs

To generate this report, run:
aps-report aps_result/--communicators_list --internal_communicators
| Communicators used in the application |--------------------------------------------------------------------------------------------------------- | Communicator Id   Communicator Size   Time(Rank Average)(sec)        Ranks |---------------------------------------------------------------------------------------------------------  4611686018431582208           4                    2.44(0.61)            0,1,2,3 |---------------------------------------------------------------------------------------------------------  4611686018431582656           4                    1.80(0.45)             0,1,2,3           |--------------------------------------------------------------------------------------------------------- 4611686018429485456 2 1.77 (0.89) 0,1 |--------------------------------------------------------------------------------------------------------- 4611686018431582608 4 1.40 (0.35) 0,1,2,3 |--------------------------------------------------------------------------------------------------------- 4611686018429485552 2 1.24 (0.62) 0,1 |--------------------------------------------------------------------------------------------------------- 4611686018431582704 4 0.86 (0.21) 0,1,2,3 |--------------------------------------------------------------------------------------------------------- 4611686018429485520 2 0.50 (0.25) 0,1 |--------------------------------------------------------------------------------------------------------- 4611686018429485536 2 0.01 (0.00) 0,1 |--------------------------------------------------------------------------------------------------------- 4611686018431582688 4 0.00 (0.00) 0,1,2,3 |---------------------------------------------------------------------------------------------------------- 4611686018429485472 2 0.00 (0.00) 0,1 |---------------------------------------------------------------------------------------------------------- 4611686018429485488 2 0.00 (0.00) 0,1 |----------------------------------------------------------------------------------------------------------

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
