<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I believe you are referring to the Scheduling Policy
described in section 3.4.7 of the Disksim 4.0 users manual and the table of
options listed on page 29.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This scheduling policy is handled in the file
disksim_ioqueue.c. When you set a value for “Scheduling Policy”,
it ends up in the member variable .sched_alg of the ioqueue struct. (Look
at the function DISKSIM_IOQUEUE_SCHEDULING_POLICY_loader in
disksim_ioqueue_param.c.)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Perhaps you could add your own scheduling algorithm to
disksim_ioqueue.c.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Once you have made your edits, rebuilding the source is as
simple as running “make”. Note: I have found it necessary to
run “make clean” before rebuilding when I make updates to an
included module such as the ssd module.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Hope that helps,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
