[jira] [Created] (SINGA-138) Performance profiling

wangwei created SINGA-138:
-----------------------------

             Summary: Performance profiling
                 Key: SINGA-138
                 URL: https://issues.apache.org/jira/browse/SINGA-138
             Project: Singa
          Issue Type: New Feature
            Reporter: wangwei


Performance profiling is useful for analyzing the bottleneck of a system, e.g., by measuring the time cost of each component (or function), the memory footprint, etc.. It is also necessary for SINGA-132.

Particularly, we first need a class (e.g., Timer/Ticker/etc) for measuring the time spent for calling a function. Second, we need to determine the functions for profiling, e.g., Layer::ComputeFeature() and Layer::ComputeGradient. Third, how to display or log the result should also be considered. Pretty printing would help for later analysis.
