Dear All,<br>I use the disksim && ssdsim for two months. I try to use them at the same time. But there is something weired. I use 10'000 traces or synthetic trace generator to test the system. Only a few traces at the beginning of trace file, more or less 200, were handled when the simulator stopped. I don't know why. Does anybody have similar experience? Please let me know. So appreciate.<br>
<br>I attach the relevant files so that some helper could take a look. Also, here is the link to my project: <span id="bc_0_58b+seedFuoD"><a href="https://www.dropbox.com/sh/nhavksi2jx5zfdg/Y8OFYsO4ux">https://www.dropbox.com/sh/nhavksi2jx5zfdg/Y8OFYsO4ux</a></span><br>
<br><br><span id="bc_0_58b+seedFuoD">I write down all the problems on
the "readme at first.txt". It is too long, so I put them into one file
according to your suggestion. The folder HybridDiskSim is the project I
am using. And my host operating system is Ubuntu 12.04 LTS.<br>link to dropbox:<br><a href="https://www.dropbox.com/sh/nhavksi2jx5zfdg/Y8OFYsO4ux">https://www.dropbox.com/sh/nhavksi2jx5zfdg/Y8OFYsO4ux</a></span><br><br><br>
<br> (1) When I use the synthetic trace for SSD, the number of maximum traces handled is 244. I don't know why.<br> the command I used like:<br> ./src/disksim example_ssd.parv example_ssd.outv ascii 0 1<br> <br>
I record the synthetic trace into the file synthetic_ssd.trace. The last item in this trace seems weird(Both SSD and HDD).<br> It should be 0 or 1, but the value is 400000003<br> <br> 0.000000 1 31853640 8 3<br>

0.662520 1 31853680 8 40000003<br> ...........................<br> <br> <br> <br> also, the ssd statistics is weird. Only 43 requests handled. Furthermore, all of 43 requests are read. No one write.<br>
