[lttng-dev] [RELEASE] Workload-kit 0.1.13

[Francis Giraldeau]

Workload-kit is a set of utilities to generate various kind of workloads on
a system, aimed at generating traces that presents recognizable features.
The generated trace set could be used as a basis to validate trace analysis
algorithms. Workload-kit makes it easy to generate the trace set on any
architecture in a reproducible way.

Changelog:
2013-05-31 Workload-kit 0.1.13
* Add cputemp utility to trace sensor temperature with UST (contribution of
Suchakra Sharma)
* Add wk-pipette to show producer and consumer behavior on pipe full/empty
conditions
* Add 3 programs involving synchronization
 * wk-mutex: simple mutex hold
 * wk-imbalance: one thread limits the computation at a barrier
* wk-pipeline: 3 stages pipeline controlled with semaphores
* Modified do_hog function to be closer to the behavior of the counter
function (contribution of Francois Rajotte)
* lttng-simple: new option --enable-libc-wrapper
* lttng-simple: increase UST buffer size to 16MB
* New option to make UST optional (--disable-ust)

The traceset has been generated with the following configuration:
* Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
* LTTng master (2.2.0-rc2)
* Linux 3.8.0-22-generic
* Includes lttng-modules add-ons

allocations with UST:
