- <modulesummary>An Overload Regulation Process</modulesummary>
- <description>
- <p><c>overload</c> is a process that indirectly regulates the CPU
- usage in the system. The idea is that a main application calls
- function
- <seealso marker="#request/0"><c>request/0</c></seealso>
- before starting a major job and
- proceeds with the job if the return value is positive; otherwise
- the job must not be started.</p>
- <p><c>overload</c> is part of the <c>SASL</c> application and all
- configuration parameters are defined there.</p>
- <p>A set of two intensities are maintained, the <c>total intensity</c>
- and the <c>accept intensity</c>. For that purpose,
- there are two configuration parameters, <c>MaxIntensity</c>
- and <c>Weight</c>; both are measured in 1/second.</p>
- <p>Then total and accept intensities are calculated as
- follows. Assume that the time of the current call to
- <c>request/0</c> is <c>T(n)</c> and that the time of the
- previous call was <c>T(n-1)</c>.</p>
- <list type="bulleted">
- <item>
- <p>The current <c>total intensity</c>, denoted
- <c>TI(n)</c>, is calculated according to the formula</p>
- <p><c>TI(n) = exp(-Weight*(T(n) - T(n-1)) * TI(n-1) + Weight</c>,</p>
- <p>where <c>TI(n-1)</c> is the previous <c>total intensity</c>.</p>
- </item>
- <item>
- <p>The current <c>accept intensity</c>, denoted
- <c>AI(n)</c>, is determined by the formula</p>
- <p><c>AI(n) = exp(-Weight*(T(n) - T(n-1)) * AI(n-1) + Weight</c>,</p>
- <p>where <c>AI(n-1)</c> is the previous <c>accept intensity</c>,
- if the value of <c>exp(-Weight*(T(n) - T(n-1)) * AI(n-1)</c>
- is less than <c>MaxIntensity</c>. Otherwise the value is</p>
- <p><c>AI(n) = exp(-Weight*(T(n) - T(n-1)) * AI(n-1)</c></p>
- </item>
- </list>
- <p>The value of configuration parameter <c>Weight</c> controls the
- speed with which the calculations of intensities react to
- changes in the underlying input intensity. The inverted value of
- <c>Weight</c>, <c>T = 1/Weight</c>, can be thought of as the
- "time constant" of the intensity calculation formulas. For example,
- if <c>Weight = 0.1</c>, a change in the underlying input intensity is
- reflected in <c>total intensity</c> and <c>accept intensity</c> within
- about 10 seconds.</p>
- <p>The overload process defines one alarm, which it sets using
- <c>alarm_handler:set_alarm(Alarm)</c>. <c>Alarm</c> is defined
- as follows:</p>
- <taglist>
- <tag><c>{overload, []}</c></tag>
- <item>
- <p>This alarm is set when the current <c>accept intensity</c> exceeds
- <c>MaxIntensity</c>.</p>
- </item>
- </taglist>
- <p>A new request is not accepted until the current <c>accept
- intensity</c> has fallen below <c>MaxIntensity</c>. To prevent the
- overload process from generating many set/reset alarms, the
- alarm is not reset until the current <c>accept intensity</c> has fallen
- below 75% of <c>MaxIntensity</c>; it is not until then that
- the alarm can be set again.</p>

- <fsummary>Requests to proceed with current job.</fsummary>
- <desc>
- <p>Returns <c>accept</c> or <c>reject</c> depending on the
