[Disksim-users] Why is SysSim time negative value?

[Wang Min]

hi, all:
     Maybe I didn't describe the question clearly. I run the runvalid script 
in DiskSim, and the last two validations are  about system-level simulation 
with DiskSim. I am confused on this results: IOdriver response time is 
19.56ms, but the total system response time is -39163.54.  Would you please 
explain it to me? Thank you very much.

The results is :
syssim: externally-controlled DiskSim (avg. resp should be about 19.6ms)
  response time: n=1000 average=-39163.548316 std. deviation=22560.393800
IOdriver Response time average:         19.561833

yours  MinWang
