Updating release notes, making debug_cols option configurable

parent 39ef9691
0.6.0 (July 03, 2017)
C++ models can now be built and integrated with CODES. The new dragonfly model
has been implemented in C++.
support has been added for building CODES with CoRTex -- a library for translating collectives
to point to point operations. For details see:
CODES wiki with details on model development, networking, MPI simulation and
more has been added at:
Test suite has been extended -- tests for DUMPI trace replay have been added.
Unused variable warnings have been fixed.
dragonfly network model based on Cray XC topology has been added. The model can
use the network configurations of Theta and Edison systems. Custom network
configurations can be generated using C scripts. For details see:
fat tree network model with support for adaptive and static routing has been
added. The model can support both full and pruned fat tree configurations. For
details, refer to the wiki:
memory consumption has been reduced by doing lazy allocation of hash memory.
MPI trace replay:
MPI rendezvous protocol can now be replayed in addition to the eager protocol.
The transition point for switching between the two protocols is configurable.
Background network communication using uniform random workload can now be
generated. The traffic generation gets automatically shut off when the main workload
Collectives can now be translated into point to point using the CoRTex library.
Performance of MPI_AllReduce is reported when debug_cols option is enabled.
Aggregate and average performance of different message size is reported when
message tracking is enabled (this option is for debugging, works in sequential
mode only).
