CPU throttling

noreply@blogger.com (Md. Aliullah) — Fri, 27 May 2022 12:48:00 +0530

Sometime we come across situation where we need to throttle or degrade CPU performance.

Suppose there is a situation you deploy your application in low performance system but development is done on high performance system.

To simulate lower performance system you need to do CPU throttling.

Here I am discussing how we can do this using Windows 11 OS. Similar feature should be available in Linux or other operating systems as well.

Assuming we are using Windows 11 OS as super user, open Performance Monitor application tool. In Windows you can open this by invoking perfmon.exe /res from search or run option. Using this tool open CPU performance monitor to monitor current CPU(s). In the GUI there are two panes. From left pane, tree view choose Performance -> Monitoring Tools -> Performance Monitor view.

In the right pane, you should see two sub-view one graph view on the top and one selected counters view on the bottom. Right click on the the bottom view and choose Add Counters.

In the pop up window choose Computer and Counters (Processor Information in our example) and target processor instances (you may choose All instances of processor or a specific instance). Right side of the pop up Window the selected counter are shown. An illustration is shown below.

Now press OK to complete the Counter and Computer selection.

In the Performance Monitor view now you should see the values of the selected counters and the current counter values in Time (X-axis) vs Counter value (Y-axis) graph. There are quite a few Processor Performance related counter. We can choose only Processor Frequency of one of CPU instance to have a simple and easy to understand graph view. An illustration added.

Now we will perform CPU throttling using power option and see the impact via the graph view. Open Control Panel > Hardware and Sound > Power Options. Click on the advanced power settings. An illustration added.

Now in the advanced power settings window, choose processor power management. Choose maximum and minimum power state. Note down your current settings before modifying the values. An illustration added.

Now change maximum processor state and apply and check in the Performance Monitor Window, the CPU the %Maximum of Frequency values getting reflected.

You can write simple script to do some computation and run the application with before and and after changing maximum processor state and to see the impact.

When done, revert your settings using noted down values.

Invest directly and earn more

Nowadays many people are interested to do investment in stock market.
Mutual Fund (MF) investment is one of the easiest way into the market to begin with.
You do not need to manage it in constant basis.

However few things you need to keep in mind while investing in MF.

Do investment online. It will empower you to buy and sell whenever you wish.

Its better to have single account to do all the transaction and track their values.

Do some research and make a list of preferred funds.Few sites to help you is
https://www.valueresearchonline.com/funds , http://www.moneycontrol.com/mutualfundindia
etc.

You will see lots fund.You need to choose as per your criteria.
You will see for each fund there is another Direct Plan. You may wonder why two name.
It has a history. Whenever you buy a fund there are 3 charges
a)Direct brokerage: Standard charge you pay to broker. Its normally 100 for investing Rs. 10,000 INR. There are broker like fundsindia.com which does not charge this brokerage.
b)Indirect Brokerage: The Fund house (say SBI MF ) gives some commission called trailing commission to the broker/agent.
c) Fund management charge.

So broker getting money directly from you as well as from the Fund House.

In 2013 SEBI instructed the Fund Houses to give customer option of direct investment so that customer can get rid of at least the brokerage. After this the so called Direct Plans came into life.

However the brokers will not offer you these funds as they will not be able to earn the trailing commission. So to buy Direct Plan you need to have account with each of the fund houses. But this is very cumbersome to manage multiple accounts with multiple fund houses.
Fortunately there is a solution as well. Use www.mfuindia.com to open a single account. Send them the documents required and get the account activated.

Now you can invest directly, and save the two brokerages a) direct brokerage you pay and b) indirect brokerage fund house pay out of your money.

Interestingly almost all of the Direct Plan shows around 1% better return than Regular plans.

Online shopping can silently help underpriviledged children

Friends,

I am associated with an NGO named Pratyush. Its a centre for downtrodden children and women.To know more about Pratyush please visit http://pratyush.org.in.

We are helping them in our capacity. And now you can help them without pinching your pocket.

Here is the mechanism.

Now a days we do lots of online shopping from online portal. These shopping portal pay very good amount of advertising fee/affiliate fee to the advertisers.

We have created one affiliate account for Pratyush in following websites:

flipkart.com, snapdeal.com, amazon.in, infibeam.com.

All the affiliate fee collected are directly going to Pratyush C D C W account via NEFT to Pratyush C D C W .

How can you help?

Whenever you wish to buy some product from any of these shopping sites, please copy the url of the product from the browser. Example http://www.flipkart.com/asus-zenfone-4-a400cxg/p/itmeygpv4uxt4gjx?pid=MOBEY2ZCDHRXUZFW&icmpid=reco_pp_hsame_mobile_mobile_6&ppid=MOBDSGU2ZMDYENQA
Now goto http://www.linkdir4u.com/pratyush/aff.php
Paste the the url you copied from the shopping website in the textbox and click on Generate link. A new link will be generated with our affiliate code added in the link.
You will automatically be redirected to site with new generated link and buy the product.

Whenever you buy the product some affiliate fee will automatically go to Pratyush account (some time even 15% ,sometime less).

So in a nutshell when your are buying a product of Rs 100 you are buying it at Rs 100 and still giving Rs 15 to Pratyush C D C W silently.

Fee free to share this knowledge with your family, friends and colleagues. And bookmark to the url http://www.linkdir4u.com/pratyush/aff.php.

An encounter with destiny - beyond patterned life

An encounter with destiny

It was Friday evening 27th Nov 2009. Next day is Eid. People were in mood for returning home for weekend as well as for Eid festival. I was one of the people intending to rejoin my family on Eid occasion. I reached Sealdah around 5.45 pm.Sealdah rail station complex was not as crowded as I expected. I was walking lazily along with my friend Bashir to catch Bhagirathi Express scheduled for 6.25 pm departure. We still had more than half an hour in our hand. Suddenly few people rushed from behind and from right side and somehow I get pushed down to ground. Usually I can take reflex action whenever I fall or about to fall. But this time it was so sharp that I could not take any action. I even fall unconscious for few moment. Bashir and People around helped me to recover from ground. When I again got my crutches in place and ready to move forward I felt acute pain in my right leg. I thought of waiting few moments before proceeding again. But the pain was showing no sign of recession. I tried to get a feel and perhaps to rub off the dust from my jeans pant. Only then I realized something serious happened. Perhaps the right femur got broken. Bashir helped me to nearby railing to stand there for few minutes before we can decide what to do next.

I again tried to get a feel of my leg. This time I became certain it indeed broken into two pieces. Luckily it was my polio affected right leg. I informed my family and office colleague who gleefully wished Eid Mubarak few minutes back. I called my nephew Dicken who was waiting for me in Sealdah complex. Dicken went to call a cab but surprisingly he could not manage to get a cab. Bashir went and finally managed to get one. Getting into the cab was really painful. Now I already knew that leg is broken so pain increased – perhaps consciousness increased pain. The driver carefully drove us to city’s famous Apollo Gleneagles Hospital. To our surprise we found emergency section did not have any orthopedic doctor at that time and they also have first pay, then admission and after that medical care policy.

The admission process was slow. Anyway when they make an X-ray I could see the broken femur. Officially I got at least 207 bones. Then they make a temporary plaster on my leg as I may have to wait for my operation slot for at least one more day .They had to use knife to remove the jeans pant I was wearing.Though we booked a private cabin I got admitted in a twin shared cabin. I was finally got into my bed at around 10.30 pm. I was placed in bed no 478 to accompany another patient at bed number 479.

Night 1 - 27th Nov Friday:

The other patient peeped out of the screen separating the two beds. He did not ask me any question neither did I. The nurse and other staff were very helpful. They got me introduced to the basic things. The senior doctor gave me a visit late at night. After having food I tried to sleep. I discovered the room is too noisy for me .Patient at 479 was snoring, sound was coming from lobby. The light was enough to keep me off the sleeping zone. I was feeling frustrated. I discovered the room had another person – employed as aya (fulltime nurse) for my fellow patient. The lady (K. Kumari) was at 22 (I came to know about her age later from the conversion I overheard) and had a female child baby of age 3 at home. She had a love marriage. I also came came to know about relative monetary benefits of diamond work in Surat to ayagiri in Kolkata. She had sacrificed the lucrative jewelery career for love and marriage. She used to earn 7 thousand to 8 thousand as jewelry worker and as aya she managed to get only around 3 thousand. She was really fatigued and working for last five days uninterruptedly – 3 duty per day each of 8 hours. She perhaps fell asleep and near her patient’s bed. A rotating almost caught her sleeping with her patient.The 479 came defended her. At around 4 am just after I get off mild sleep I saw blood was coming into the saline tube as saline water finished .The aya stopped the saline tube and perhaps any further damage. I did not know that patient needs to keep track of saline status and inform nurse accordingly for change. The night passed eventless except I had to hear the all the heroics of neighbor patient from his conversation with his aya.

To be contd:

Changing the system from within the system.

noreply@blogger.com (Md. Aliullah) — Sun, 30 Nov 2008 15:53:00 +0530

Do we need an emergency situation to awake?

Yes we do need one most of the time.

We only get awake when a Parliament attack, Mumbai attack, Samjhouta express attack, Mumbai local Train attack etc do occur. The problem is not that we get awake when the crisis occurs. But the problem is we fall back to sleep when the crisis is over.

Let’s stop doing falling back to sleep.

Whenever a crisis occurs the first thing we think is that we need change the system.

We essentially first point our finger to the corrupt politics system, intelligence system, police system etc. The more we can name the more points we score as if we are in a mission only to find who the culprits are.

I have a problem with this notion of only fault finding and essentially taking no action based on the finding. Who comprises the system? None but us. The collective individuals comprise the system. It’s we who give birth to a corrupted system and continue to feed the system with corruption in everyday. How?

Let me give some example?

A teacher needs to teach and to evaluate how much he was able to teach through the evaluation process. We sometime shamelessly devalue the evaluation process to hide the root problem that’s we fared badly as teacher.
A leader who needs to lead and formulate guideline and go by the rules forgets the importance of the guidelines and rule and very reason of creating those rules and take decision which suits the short-term purpose.
A subordinate worker rues about the leadership in company of his co-worker but seldom take things where it matters.
A driver defies the rules of the road and blames the traffic system.

The example grows. We ourselves play all these roles in everyday life. Whenever we are breaking a rule however insignificant that may sound, we basically weakening the very nation we are part of. Every time we are lighting a cigarette in a public place we are weakening our very national hood. Every time we are throwing plastic tea cup here and there we are breaking the rules. Every time we are complaining for over checking of our luggage we are expecting the system to get corrupted to spare us.

We need a healthy system where every actor plays their part and whenever we feel some of the rules needs change let’s play our part of changing the rules in the appropriate forum but let’s not start breaking the rules and also not allow other to break. We must own them. This we must practice to make our nation a developed nation and a nation with pride.

Climb up and also learn to come down gracfully if needs be

noreply@blogger.com (Md. Aliullah) — Tue, 30 Oct 2007 19:55:00 +0530

People find it quite easy to climb up - not just rock or careerer ladder rather I will say all sort of upward activity.
But when comes the term to go back to where we started from or say somewhere down the line some of us do fare terribly. It's sort of tumbling down .
Why this happen ? May be I do not have the answer to the question or rather there is nothing called tailored made answer to all our queries .
Recently I have some kind of upward movement and the movement was very quick.
To be more specific I had an climbing experience that took just 2 weeks to go up and reach the peak. And I had to come down in just 3 days. I was not ready either for the quick climbing up or the trembling down.

After a few days I started analyzing the events and came up with my own explanation about the eventuality and I how reacted.

When I started climbing up I did never set out my destination and my primary aim was to to reach the goal. As if the journey only involves a call to start and reaching the tip point. In the path I never felt about the incremental upwards effect I was undergoing. But the incremental ups were making me reach there. And when I reach the peak and was told to reverse back I was upset. After reaching the peak I found myself really far away from I where began. It took incremental effort to reach the point. And from the decision point I never anticipated about reversing back or say about the failure. I thought only about further up. The sudden reverse gear made me feel bad. I knew only about incremental upward movement but not about graceful climbing down in a rather less time. And that's why we people overreact.

The lesson I learnt is be ready to face all the possibility. And when you reach your current goal you may need to think about further upward movement or may be reverse back but not beforehand. But if you really need to reverse back just take it as a new path and forget about the direction. That will save you from overreacting. And frankly speaking this idea helped me to a great extent to climb down gracefully.
