[Disksim-users] Using Parameter overrides on General inter-arrival time / Parameters with LIST type input

[Kwan Yann Howe]

Hello one and all,

I've to change this parameter (General inter-arrival time) quite alot and I
noted from over here that disksim 3.0 is unable to override this parameter

https://sos.ece.cmu.edu/pipermail/disksim-users/2006-February/000019.html

I'd just like to know if that has been changed in 4.0? I can't seem to
override i from the command line. Here is what I tried,

nice ../src/disksim 'Seagate-Cheetah15k5-10Hz.parv' output-FCFS-10Hz.outv
ascii 0 1 disk0 "Scheduler:Scheduling policy" 1 disksim_synthgen "General
inter-arrival times"  "[exponential, 0.1, 0.0]"

Here are my generator parameters.

disksim_synthio Synthio {
  Number of I/O requests to generate =  10000,
  Maximum time of trace generated  = 100000.0,
  System call/return with each request = 0,
  Think time from call to request =  0.0,
  Think time from request to return =  0.0,
