<div><p>At times, your application can benefit when a thread yields the
|
||
|
|
processor to another thread in the system.</p>
|
||
|
|
<div class="section"><p>When a thread yields the processor, it immediately allows another
|
||
|
|
equal or higher priority thread that is active in the system to run. If no
|
||
|
|
threads of at least equal priority are currently ready to run, yielding the
|
||
|
|
processor has no effect. Beyond the immediate action, yielding the processor
|
||
|
|
does not have any additional predictable behavior related to the scheduling
|
||
|
|
of the threads in the system.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><p>The iSeries™ server
|
||
|
|
provides a fully preemptive multitasking scheduling algorithm. A thread that
|
||
|
|
exists in a well-written application should seldom need to yield the processor
|
||
|
|
to other threads. This is because more predictable application programming
|
||
|
|
interfaces (APIs) for synchronizing threads are available.</p>
