I would appreciate if someone knows the work around and take some time to answer this question. Thanks!
Hi,
I am using TPC-C trace but I am not able to make it work.
LBA in TPC-C trace is very large than the range of the unsigned long
int. How can I make this trace environment suitable to simulation
environment? I tried changing the value of 'locScale' in I/O mappings
block in parameter file but it doesn't work for me.
For example:
Request 1: 3247.201 0 276996096 3 0
It gives following error:
unexpected request location: devno 0, blkno 276996096, bcount 3
Assertion failed:
simtime = 3247.201000
totalreqs = 1
disksim: disksim_logorg.c:763: logorg_maprequest: Assertion `logorgno != -1' failed.
Aborted
Request 2: 5288.554 0 3201773568 16 0
It gives the following error:
unexpected request location: devno 0, blkno 2147483647, bcount 16
Assertion failed:
simtime = 5288.554000
totalreqs = 1
disksim: disksim_logorg.c:763: logorg_maprequest: Assertion `logorgno != -1' failed.
Aborted
In the second request, LBA value gets rounded in the range of long int. How can I fix this problem?
Thank you!
Janak
