When no files are listed for one the specified directoris, the
instrument checks whether there are any files in that directory on the
device. If that directory itself does not exist; that will result in an
error. This is now handled correctly.
The warning refers to trace.bin, which is not the extension that we use
for it. Instead, use the variable with the default trace
name (trace.dat) for the warning.
- fixed_before_start is a fixed time period equivalent to
temperature_before_start
- Changed existing *_between_specs and *_between_iterations callbacks to
be very_slow, as they should always run after everything else.
A quadratic is now fitted to single and two-core power measured across
frequencies. This quadratic is then used in projection of cluster power.
This mitigates issues with cluster powers going negative or "crossing
over".
Added -p option to the list command. This alows filtering results by
supported platforms, e.g.
wa list workloads -p linux
Also adding missing supported_platforms attribute to various extensions.
If an extension does not have this attribute, the assumption is that it
is supported by all available platforms.
- updated energy_model to accept dhrystone as well as sysbench as
the workload
- added "threads" parameter to sysbench (basically, an alias for
"num_threads") to be consistent with dhrystone
- added "taskset_mask" parameter to dhrystone to allow pinning
it to specific cores.
- Now works with earlier versions of the DAQmx driver. This is needed to
be able to run the server on Linux systems, which support older
verisions of the driver only.
- DAQ error messages are now properly propaged to the client (PyDAQmx
uses "mess" rather than "message" attribute to store the message in
the Exception obejects).
- pylint and pep8 fixes
Some options in config_example.py are not reachable. It makes users
confused. So make the options in the file as gobal_alias.

list_or_* functions (e.g. list_or_string) will now always return a list,
however will accept lists or indivitual values. Also added a list_or()
generator function, similar to what already exists for list_of().
As instrumentation can be enabled/disabled for a specfic workload
execution, it is sometimes not enough to verify that an instrument has
been installed for the run; one might need to check whether it is
currently enabled.
np.vectorize was being unconditionally invoked at top level. On an
ImportError, np as set to None, so this was resuling in an
AttributeError when loading the module if one of the dependent libraries
was not present on the host system. This moves the invocation into the
try block with the imports to avoid an error when energy_model module is
loaded by the extension is not used.
Make sure when migrating sshd to root cgroup also migrate their
children, including the bash for the wa session. So the subsequent
processes kicked off from that shell can be taskset to any cluster.
Matplotlib defautls to the GTK backend. This can cause problems when
running in a headless session (e.g. over SSH). Since energy_model
istrument generates PNG plots, rather than rendering directly to UI, it
doesn't actually need GTK; set backend to AGG so that energy_model works
in headless environments.
This instrument can be used to generate an energy model for a device
based on collected power and performance measurments. The instrument
produces a C file with an energy model and an accompanying HTML report.
This instrument is very different from other instrumentation, as it
actually generates the run queue on the fly based on the operating
frequencies and idle states it discovers on the device. The agenda needs
only to contain the single "base" spec that defines the workload to be
used for performance measurement.
