[Disksim-users] Problem about stopping simulation because of saturation

[cq25062030]

Hi all,

I'm a freshman  of using DiskSim. Recently, I try to implement a simply Garbage Collection algorithm based on the ssd model source code provide by Microsoft, I only modify a part of  the ssd_clean.c file, and make a little change about the initialization function. The source code of DiskSim is kept the same as before. And I use the same test case as  Microsoft provided, but when I try to run the new code, the DiskSim give an error message like: Stopping simulation because of saturation..... 

This problem occurs when run the ssd-rw5m and ssd-postmark  test case.

I try to reduce the size of the request by modifying the configuration file as the website

https://sos.ece.cmu.edu/pipermail/disksim-users/2010-July/000516.html, 

the number of  simulated  request grows, but the problem occurs again at last. Also I try to debug the program, I find that the requests keep arriving, but little operation about issuing them, I can't find the reason that leads to generate this problem.

Could anyone give me some advice to solve  this problem? 

Thanks a lot.

Best wishes,

Qian Cheng.
