Message-ID: Hi, everybody, I need you help:-) When I set the "I/O Trace Time Scale" in disksim_iosim to 1, the simulator shows a saturation error before. But when I change "I/O Trace Time Scale" in disksim_iosim to 10, the error disappeared. I think that is because the "request arrival time" of the trace file is too small, which results that the number of the arriving requests in one second is more than ones that the simulator could deal with in one second. So I change the "I/O Trace Time Scale" in disksim_iosim to 10. Next, I run it again, but the weired result made me crazy. When I ran disksim using my ascii trace file, the overall response time, almost 20000, is too big to believable. Do anybody could tell me the reason and how to solve this problem. Thank you so much. I am so appreciated. I set the "request arrival time" like the following style. 0.5 0.75 1 1.2000 1.4000 1.5000 1.7000 2.0 ..... Hopefully, it could give some hints to find out my problem. Thanks.

Perhaps that will help the last person who asked about a libm issue. Also, there's a couple disksim projects on github. Maybe there are fixes there for everyone. :) Greetings, Michael.

Message-ID: Long, Michael is right. The original version works on 32-bit machines only. There is another option. It is easy for you to find tutorials as well as corresponding patches from the web or the maillist, to help you compile DiskSim on 64-bit machines. In my memory, There are at least two or three tutorials available on the web. Lei On Aug 26, 2012, at 2:02 PM, stroucki at ece.cmu.edu wrote: > Disksim is for 32 bit machines only.

I am new to DiskSim, and want to try it on Ubuntu 64bit. But when I compile it, I just get some compile errors. I find some solutions from internet, e.g., adding -m32 gcc flag. However, after adding -m32 flag I still encounter other problems, e.g., missing header files due to all header files that I owned are of 64bit version. Would simply coping header files of 32bit version to my /usr/include/ directory makes it work? Or is there a complete guide to help me compiling DiskSim in 64bit environment? Thanks.
