good evening.
I just guessed that your setting of the path of gridsim.jar and simjava.jar
may be not done. (or other path of java library.)
I am uesing A soft named NetBeans IDE 5.0, you can set library easily when
using it. You can get if for free.
Hope to help you.
good luck,
yours,

Hello, In the web site of GridSim (http://www.gridbus.org/gridsim/) there are instructions on how to use GridSim with Eclipse <http://www.gridbus.org/gridsim/paper/eclipse.pdf> or JBuilder <http://www.gridbus.org/gridsim/paper/jbuilder.pdf> or JCreator <http://www.gridbus.org/gridsim/paper/jcreator.pdf>. I think all of them have free versions. Regards, Agustin yangyu escribió: > good evening. > I just guessed that your setting of the path of gridsim.jar and > simjava.jar may be not done.

Good morning Agustin,
Good morning everyone,
=20
Thank you very much for the information you gave to me.
I am happy to hear that the speed of PEs can be changed when the =
simulation is running.
I just tried one way to change the speed of PEs. It seems that it does =
not work .(Forgive me if I chose a wrong way to write the code) I am not =
sure the method I used is right or not.
Can you tell me why I can not change the speed(rating) of PEs when you =
are not busy?
=20
Thank you very much.
PS. I found that in the Class ResourceCharacteristics, the method =
setResourceID(int id) does not work.(I can not make resources ID as I =
want them to be.)
=20
=20
bestwishes,
yang,
---------the code--------------------------------------------------
_/*I ran this program step by step to see "rate"and "rate_change".I =
found that they were same*/
public void changePE(){
int rate=3D0;
int rate_changed=3D0;
PEList pelist=3Dresource.getMachineList().getMachine(0).getPEList();
int num=3Dresource.getNumPE();
=20
/*to see the rate of PEs before change them. there were 6PEs and each =
PE~s speed is 200*/
for(int i=3D0;i<num;i++){
rate=3Dpelist.getMIPSRating(i);
}
=20
/* try to change speed to 1000 using the method that I know*/
for(int i=3D0;i<num;i++) {
pelist.add(new PE(i,1000));
// PE pe=3Dnew PE(i,1000);
// pe.setMIPSRating(1000);
}
MachineList mList =3D new MachineList();
mList.add( new Machine(0, pelist) );
String arch =3D "Sun Ultra"; // system architecture
String os =3D "Solaris"; // operating system
double time_zone =3D 0.0; // time zone this resource =
located
ResourceCharacteristics resource =3D new ResourceCharacteristics(
arch, os, mList, =
ResourceCharacteristics.SPACE_SHARED, time_zone, 1);
// PEList pelist1=3Dresource.getMachineList().getMachine(0).getPEList();
/* to check that they are changed or not*/ =20
for(int i=3D0;i<num;i++)
{
// rate_changed=3Dpelist1.getMIPSRating(i)
rate_changed=3Dpelist.getMIPSRating(i); =
//rate_changed is same as rate.=20
}
}

Hello YangYu,
Sorry for the late reply, but I've been busy these days.
I think that what you say can be done in a similar way as the resource=20
failure functionality.
This is, computing resources could change the speed of their PEs in=20
response to an event.
If you do this, you should consider the allocation policy in place, as=20
in the body function of the space-shared allocation policy the rating of =
the PEs of the resource are retrieved.
So, more concretely, the GridResource class should receive the event=20
(perhaps the event could be sent by the GIS, as in the resource=20
failure). Then, update the PE class with the new rating by going through =
the ResourceCharacteristics class, to the MachineList, to the PEList=20
until you get to the actual PE you want to modify. If you use=20
SpaceShared policy, update the PEs rating also in this class.
Normally, allocation policies consider that all the PEs of the same=20
machine are identical, so you should take it into account when changing=20
the PE rating, and keep it always like that.
Hope that this is useful. Do not hesitate to ask again if you still have =
doubts.
Regards,
Agustin

Hello,
I am not using any kind of IDE's I m just compiling directly in the
shell. Is dat i need to use any special IDE's to work with this gridsim tool
and if so please help get me the exact steps of how to work with this tool.
I m using Centos 4. I ve also installed JSDK as said by Srikumar Venugopal.

Hi,
You dont need to use IDEs however it would help a lot if you did.
If you have downloaded and installed Sun JSDK, ensure that :
1. GCJ is not in the path
$ which java
should return the path of Sun's Java binary.
2. Your classpath is set.
Like an earlier email said, ensure that the two jars (gridsim and
simjava) are in your classpath.
$ export CLASSPATH=<path>/gridsim.jar:<path>/simjava.jar
where <path> is the directory in which you have put the jar files
Run again. Go over the instructions provided in the GridSim
distribution. They are pretty detailed.
On an unrelated note, I noticed earlier that you are running java in
the root account. While this has *no effect* on GridSim's performance,
it is generally a good idea (security-wise) to execute *all* programs
from a user account.
Cheers
Sri.
