Hi,
Like Lei, when I runvalid DiskSim 4.0, I am getting mismatching results. I have
tried this on a OS 10.4 with gcc version 4.0.1. Also tried it on a linux box and
got the same mismatching outputs.
Any ideas on what the problem might be?
Thanks,
Cagdas
Hi,
I compiled the source code of disksim 4.0 successfully on my virtual machine
(Fedora Core 4), and ran runvalid and memsvalid files under the valid directory.
The results are as follows, and it seems that,
1) for runvalid, some simulation results are not the same as expected, please
see the results marked in red.
2) for memsvalid, it looks like there is no mems.g3.parv file under the valid
directory.
Thanks,
Lei
