(The -profiling is done via a sampling method, where by default we take 100 -samples a second. Therefor one unit of time in the output corresponds -to about 10 milliseconds of execution time.) The "local" time is the -time spent executing the instructions directly contained in the -procedure (and in any other procedures that were inlined into the -procedure). The "cumulative" time is the sum of the "local" time and -the time spent in any callees. If the cumulative time is the same as -the local time, it is not printed.</p> - -<p>For instance, the timing information for test_main_thread() -indicates that 155 units (about 1.55 seconds) were spent executing the -code in <code>test_main_thread()</code> and 200 units were spent while -executing <code>test_main_thread()</code> and its callees such as -<code>snprintf()</code>.</p> - -<p>The size of the node is proportional to the local count. The -percentage displayed in the node corresponds to the count divided by -the total run time of the program (that is, the cumulative count for -<code>main()</code>).</p> - -<h3>Edge Information</h3> - -<p>An edge from one node to another indicates a caller to callee -relationship. Each edge is labelled with the time spent by the callee -on behalf of the caller. E.g, the edge from -<code>test_main_thread()</code> to <code>snprintf()</code> indicates -that of the 200 samples in <code>test_main_thread()</code>, 37 are -because of calls to <code>snprintf()</code>.</p> - -<p>Note that <code>test_main_thread()</code> has an edge to -<code>vsnprintf()</code>, even though <code>test_main_thread()</code> -doesn't call that function directly. This is because the code was -compiled with <code>-O2</code>; the profile reflects the optimized -control flow.</p> - -<h3>Meta Information</h3> - -<p>The top of the display should contain some meta information -like:</p> -<pre> - /tmp/profiler2_unittest - Total samples: 202 - Focusing on: 202 - Dropped nodes with <= 1 abs(samples) - Dropped edges with <= 0 samples -</pre> - -<p>This section contains the name of the program, and the total -samples collected during the profiling run. If the -<code>--focus</code> option is on (see the <a href="#focus">Focus</a> -section below), the legend also contains the number of samples being -shown in the focused display. Furthermore, some unimportant nodes and -edges are dropped to reduce clutter. The characteristics of the -dropped nodes and edges are also displayed in the legend.</p> - -<h3><a name=focus>Focus and Ignore</a></h3> - -<p>You can ask pprof to generate a display focused on a particular -piece of the program. You specify a regular expression. Any portion -of the call-graph that is on a path which contains at least one node -matching the regular expression is preserved. The rest of the -call-graph is dropped on the floor. For example, you can focus on the -<code>vsnprintf()</code> libc call in <code>profiler2_unittest</code> -as follows:</p> - -<pre> -% pprof --gv --focus=vsnprintf /tmp/profiler2_unittest test.prof -</pre> -<A HREF="pprof-vsnprintf-big.gif"> -<center><table><tr><td> - <img src="pprof-vsnprintf.gif"> -</td></tr></table></center> -</A> - -<p>Similarly, you can supply the <code>--ignore</code> option to -ignore samples that match a specified regular expression. E.g., if -you are interested in everything except calls to -<code>snprintf()</code>, you can say:</p> -<pre> -% pprof --gv --ignore=snprintf /tmp/profiler2_unittest test.prof -</pre> - - -<h3>Interactive mode</a></h3> - -<p>By default -- if you don't specify any flags to the contrary -- -pprof runs in interactive mode.

This will artificially - inflate the count for that symbol. - <li> If you run the program on one machine, and profile it on - another, and the shared libraries are different on the two - machines, the profiling output may be confusing: samples that - fall within shared libaries may be assigned to arbitrary - procedures. - <li> If your program forks, the children will also be profiled - (since they inherit the same CPUPROFILE setting). Each process - is profiled separately; to distinguish the child profiles from - the parent profile and from each other, all children will have - their process-id appended to the CPUPROFILE name. - <li> Due to a hack we make to work around a possible gcc bug, your - profiles may end up named strangely if the first character of - your CPUPROFILE variable has ascii value greater than 127. - This should be exceedingly rare, but if you need to use such a - name, just set prepend <code>./</code> to your filename: - <code>CPUPROFILE=./Ägypten</code>. -</ul> - - -<hr> -<address>Sanjay Ghemawat<br> -<!-- Created: Tue Dec 19 10:43:14 PST 2000 --> -<!-- hhmts start --> -Last modified: Fri May 9 14:41:29 PDT 2008 -<!-- hhmts end --> -</address> -</BODY> -</HTML> http://git-wip-us.apache.org/repos/asf/incubator-quickstep/blob/9661f956/third_party/gperftools/doc/designstyle.css ---------------------------------------------------------------------- diff --git a/third_party/gperftools/doc/designstyle.css b/third_party/gperftools/doc/designstyle.css deleted file mode 100644 index 29299af..0000000 --- a/third_party/gperftools/doc/designstyle.css +++ /dev/null @@ -1,109 +0,0 @@ -body { - background-color: #ffffff; - color: black; - margin-right: 1in; - margin-left: 1in; -} - - -h1, h2, h3, h4, h5, h6 { - color: #3366ff; - font-family: sans-serif; -} -@media print { - /* Darker version for printing */ - h1, h2, h3, h4, h5, h6 { - color: #000080; - font-family: helvetica, sans-serif; - } -} - -h1 { - text-align: center; - font-size: 18pt; -} -h2 { - margin-left: -0.5in; -} -h3 { - margin-left: -0.25in; -} -h4 { - margin-left: -0.125in; -} -hr { - margin-left: -1in; -} - -/* Definition lists: definition term bold */ -dt { - font-weight: bold; -} - -address { - text-align: right; -} -/* Use the <code> tag for bits of code and <var> for variables and objects. */ -code,pre,samp,var { - color: #006000; -} -/* Use the <file> tag for file and directory paths and names. */ -file { - color: #905050; - font-family: monospace; -} -/* Use the <kbd> tag for stuff the user should type. */ -kbd { - color: #600000; -} -div.note p { - float: right; - width: 3in; - margin-right: 0%; - padding: 1px; - border: 2px solid #6060a0; - background-color: #fffff0; -} - -UL.nobullets { - list-style-type: none; - list-style-image: none; - margin-left: -1em; -} - -/* pretty printing styles.
