A preliminary warm-up pass is used before timing the first loop in order to ensure that the CPU is brought out of power-saving modes and that system caches are warmed up. Most modern CPUs provide a "turbo" mode where the CPU clock speed is increased (e.g. by a factor of two) when only one or two cores are active. If the CPU grows excessively hot (due to insufficient cooling), then it may dial back its clock rates as a form of thermal management. These factors result in an under-reporting of speedup compared to if "turbo" mode was disabled and the CPU does not need to worry about thermal management. The <strong>powertop</strong> utility available under Linux and Solaris provides a way to observe CPU core clock rates while a benchmark is running.</em> </td></tr></table> <p> <i><a href="#top">Back to Contents</a></i> </p> <table BORDER=0 WIDTH="100%"> <tr> <td ALIGN=LEFT bgcolor="#FFFFFF"><img SRC="images/right_triangle.png" ALT=">" BORDER=0 height=14 width=15><b><font face="Helvetica, Arial"><font color="#00B04F"><font size="+1"> <a NAME="bench-opti"></a>Options </font></font></font></b></td></tr></table> <table width="94%" border="0" cellspacing="0" cellpadding="8"> <tr><td width="3%"><br></td><td> <p> Options are processed from left to right and must appear before any argument. <table BORDER=0 WIDTH="94%"> <tr> <td width="3%"><br></td> <td ALIGN=LEFT BGCOLOR="#FFFFFF"> <img SRC="images/right_triangle_option.png" ALT=">" BORDER=0 height=14 width=15><b><font face="Helvetica, Arial" ><font color="#00B04F"><font size="+1"> -duration <i>duration</i> </font></font></font></b></td></tr></table> <table width="90%" border="0" cellspacing="0" cellpadding="8"> <tr><td width="6%"><br></td><td>duration to run benchmark</td></tr></table> <table width="90%" border="0" cellspacing="0" cellpadding="8"> <tr><td width="6%"><br></td><td><font size="-1">Specify the number of seconds to run the benchmark.
