Hi, <div><br></div><div>It really works!! Including Number of parallel units = 1,2,4</div><div>But original should be "tmp->blkno = blkno"; not "tmp->blkno = tmp->blkno;" Thanks anyway. :D </div>
<div>Now I have a new problem about saturation msg while Plane block mapping = simple concatenation in postmark trace</div><div>I will try first, thank you very much.</div><div><div><br><div class="gmail_quote">2011/5/25 <span dir="ltr"><<a href="mailto:disksim-users-request@ece.cmu.edu">disksim-users-request@ece.cmu.edu</a>></span><br>

Hi all,<br>
I have some question about using ssd-add-on.<br>
I have made it work properly in default setting while<br>
runvalid(/ssdmodel/runvalid)<br>
but while I modified the parameter in ssd spec, "Plane block mapping"<br>
and "Number of parallel units", there is something wrong.<br>
when I set Plane block mapping = 1 and Number of parallel units = 2,<br>
synthetic workload "rw5m" and real traces "iozone" will generate<br>
segmentation fault.<br>
moreover, Plane block mapping = 3 and Number of parallel units = 2<br>
Plane block mapping = 1 and Number of parallel units = 4<br>
Plane block mapping = 3 and Number of parallel units = 4<br>
these parameter has same result.<br>
<br>
All I did is modified this two parameter, I can't figure out why there<br>
is a segmentation fault<br>
Is there anything I missed?<br>
Please help me, I will appreciate your help<br>
<br>
Best Regards<br>
<br>
<br>

hi~<br>
<br>
maybe try to add a line in the function of " ssd_media_access_request_element<br>
"<br>
original:<br>
tmp->blkno = tmp->blkno;<br>
<br>
modified:<br>
tmp->blkno = tmp->blkno;<br>
tmp->opid = curr->opid;<br>
<br>
good luck<br>
<br>
