It took me some time to find out how to do so, and here it is.

To compile Disksim 3.0 on Ubuntu, you need to install following
packages:
sudo apt-get install flex-old
sudo apt-get install gcc-2.95

then in the source directory, type:
make CC=gcc-2.95

I compiled Disksim 3.0 use gcc4.2 on  fedora 8 and successful.
Is there any problem useing gcc4.x ?

Message-ID: <614944.256871206492812688.JavaMail.coremail@bj126app85.126.com>

 I'm using disksim-3.0.
 
Run disksim as follows,it's OK!
/disksim ascii.parv ascii.outv ascii ascii.trace 0
 
//ascii.parv & ascii.trace are the files provided by the disksim itself( in  ../valid/)
 
Then I edit ascii.parv, change the scheduling policy into 8 (3 original)which represents SPTF_OPT.
Run it again,the result shows as follows:
/disksim ascii.parv ascii.outv ascii ascii.trace 0
RETURNING NULL!!
RETURNING NULL!!
RETURNING NULL!!
RETURNING NULL!!
RETURNING NULL!!
RETURNING NULL!!
RETURNING NULL!!
.....
 
Why? SPTF_OPT is widely used in real system ,disksim must have implemented it,but how does this happen...Looking forwards to your answers!!Thank you!!
 Best wishes!!

Subject: [Disksim-users] disk head position to logical block number and vice
	versa
Message-ID: <854da8df0803251949r3bc2b1cdw54c8ac69910b48fe@mail.gmail.com>

Hi, I was trying to find out how to get logical block number from given disk
head position by structure, currdisk->mech_state

i was using
currdisk->model->layout->dm_convert_atop(currdisk->model,&mech_state,&pbn);
to get the physical block number and then,
rval=currdisk->model->layout->dm_translate_ptol(currdisk->model, &pbn, 0);
to
get corresponding logical block number. Not sure, if this is the right thing
to do ?

Furthermore, i was looking at the disksim code, for disksim_diskctlr.c ,
line no. 3987 ( version 3),

 currdisk->model->mech->dm_latency(currdisk->model,
                          &startstate,
                          curr->cause,
                          curr->bcount,
                          immed,
                          0);

curr is current request event, and i think its cause field denotes the
starting sector from/to which data needs to read/written.
the conversion of this sector to angle uses dm_pbn_skew , but if i convert
this angle to get pbn, its sector comes to be different.
Any suggestion, why this may happen?

thanks and regards,
ashok

Hi, all
In my simulation platform, disksim is set as a slave component. When system level program read I/O requests from I/O tracefile, the time interval between any two requests are the actual time. However, the time dimension in disksim is not equal to the actual time. What i should do to coordinate these two time dimensions when i issue external requests into disksim ?

I believe that the manual talks about how to do this, and that there is
also example code in the distribution.  In a nutshell, you need to have
disksim time advance with simulation time (and the master simulator should
be reading the tracefile and feeding requests to disksim, if disksim is
part of a larger simulator).

Good luck!

Hi,

I figured the conversion from angle to physical ( The manual does talk about
it at end :) ).. Now I am trying to find out in the disksim code, where
calculation for rotational latency take place, and where actually statistics
gets updated for the corresponding rotation.. Any quick pointer to this,
would be quite useful!

Thanks,
ashok

Subject: [Disksim-users] asynchronous callback
Message-ID: <200803270839542186095@gmail.com>

In syssim_driver.c, there are N requests issued into disksim. However, they are synchronous, the second request is issued when main() the first request completed. In my implementation,  i want to issue requests from iotracefile according to their actual time interval. 
 
In other words, the example in syssim_driver.c is synchronous and i want to implement asynchronous. 
 
( I want to issue the second request got from iotracefile before the completion of the first request )

How can i accomplish this purpose?




Best regards!
Yinliang
