# CUDA Profiling Library

This library provides an API for collecting CUDA profiling metrics and events

from within a CUDA application. Programmers specify what metrics and events

they want, and start the profiler before calling one or more CUDA kernels. The library

sets up the appropriate CUPTI callbacks, calculates the number of

kernel passes required, gathers values for the specified

metrics and events, and returns them to the programmer on a per-kernel basis.

**Example Usage:**

``` c++

  vector event_names {

                              "active_warps",

                              "gst_inst_32bit",

                              "active_cycles"

                             };

  vector metric_names {

                               "flop_count_dp",

                               "flop_count_sp",

                               "inst_executed"

                              };

  cupti_profiler::profiler profiler(event_names, metric_names);

  // Get #passes required to compute all metrics and events

  const int passes = profiler.get_passes();

  profiler.start();

  for(int i=0; i
