ChangeLog

EZTrace now generates OTF2 traces
Many changes to EZTrace internals
Added an IOTracer module for tracing kernel IO events.
Added an OMPT module. It traces OpenMP events using the OMPT interface.
Some EZTrace modules or features are temporarily unavailable: CUDA, StarPU, PAPI, eztrace plugin creator. We will port them to the new OTF2 format soon

Add support for CUDA applications
Add a script that generates an EZTrace plugin directly from an executable program
EZTrace now relies on LiTL (instead of FxT) for recording events
EZTrace can now track the CPU on which a thread run
Add a sampling interface that allows to call a function every x ms
EZTrace is now under the CeCILL-B license

EZTrace now supports MPI3 application that use non-blocking collective communications.
Fix EZTrace handling of MPI communicators in collective communications
Add options in eztrace and eztrace.old to manipulate various environment variables (EZTRACE_TRACE, EZTRACE_OUTPUT_DIR, etc.)

EZTrace now relies on Opari2. Thus, OpenMP 3.0 programs can be analyzed
EZTrace provides two trace flush policies: the trace is written to disk only at the end of the program (thus, some events may be lost, but there is no overhead) or when the event buffer is full (thus, no event lost, but there's an overhead when the trace is being written to disk)
EZTrace now implements a trace synchronisation mechanism
EZTrace can now instrument functions located inside the application or in a statically-linked library(it does not require to be dynamically linked anymore)

EZTrace can now use PAPI (Performance Application Programming Interface) for extracting hardware counters
Update the OpenMP module. It can now use Opari for instrumenting OpenMP program and extract precise informations
Fix the generation of OTF traces
Improve statistics on MPI messages

Add a module for standard IO primitives (read, write, select, ...)
Add a module for tracking memory consumption (malloc, free, ...)
EZTrace can now rely on DynInst for instrumenting programs/static libraries.
Add a source-to-source compiler (eztrace_create) for converting simple scripts into eztrace plugins
FxT and GTG (with OTF support) are now included in eztrace. Thus, you don't need to download/install them separately.

EZTrace now relies on modules (plugins).
EZTrace now supports user-defined plugins.
EZTrace now works on Mac OS X. However, since mac os pthread interface is limited compared to the linux one, the pthread module is not available on macos.
The Coreblas module has been removed. It is now part of the Plasma project.
eztrace_stats is now available. Instead of merging traces, it computes statistics on the traces (number of events, average size of MPI messages, etc.)
Fix various bugs in PThread and MPI modules.

Add full support for MPI communication operations (for both C and Fortran bindings)
Add support for OpenMP scheduling strategies (static, dynamic, guided and runtime)
Fix various bugs in PThread, OpenMP and MPI modules
