Fwd: Re: New Metrics to measure Load average

Hi Balbir Singh,

I have done changes to the load average inside current functions.
This means without introducing any new function.

Please go through our previous correspondence in this regard.

Also I had discused this fact with Peter Williams who had introduced some new functions in the same area.

Would do you be able to test my code?

Kind regards

Dear Balbir Singh,

This is one of the e-mails probably the last.
By this time I have finshed 2.4.19 kernel.

Dear Balbir Singh,

Thanks for your reply and for your time.

Then I will have to transfer from 2.4.18 to 2.6.18

Ok Balbir I will do that.

Dear Balbir Singh,
Thanks for your valuable reply.
Balbir It looks like that there is a general project where we all can incorporate our work.


Yes it is. It is currently in -mm and we hope that it makes it into
2.6.18. The folder Documentation/accounting contains all the necessary
details for you to build on top of delay stats.


--How do you calculate disk load? Is it the
---number of uninterruptible tasks in the system? Yes I started at that point

Few years ago the few additions I have explained, have been implemented in linux 2.4.18 kernel at the Sydney Uni as part of a large research project.
Also few years ago I have posted many posts about this topic to this forum. Few very experience hands were advising me in coding at that time. To prove this I have all the e-mails with me. Yet then I had not explained to this forum about the research project which involved prediction algorithm as then it had not been published.
Thereafter few research papers have been published with regard to this. 1 in US.
Currently I am preparing the changes to a more recent linux patch. In fact this is not hard as I have already changed the previous linux 2.4.18.

Please cc us when you post the patches.

Before coming to do research I had worked as a Senior software engineer in few companies and my last was LogicaCMG. Yet as far as the kernel programming is concerned I will ask for your comments and advice.

Let us know if you need any help for coding on top of taskstats.

Thanks
