[Disksim-users] Having problem using TPC-C trace with Disksim

[janak patel]

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!
