Graphic Cards and GPU

It all started with a transistor, capacitor and  logic gate when I was in school.
There were no Printed Circuit Boards, then.
I tried a one transistor radio then (not a valve). It did not work and needed a high antenna.
I have up and did medicine.
Did not give up learning transitotor technology and mose code and many circuits and a radio.
I bought a set up with 3 transistors from RadiShack in UK.
I still have it and it is still working.
Duodes were not able then.


Belore is and array of technological terms used in Video Games.

GPU is the actual chip.
Graphic Processing Unit

SLI


Multi Processor GPU
Crossfire


Redeon

GeForce 

Built by 

AMD


NVIDIA

Memory
4GB VRAM is the minimum specification for gaming.

More the better 32 to 64 VRAM

Core Clock and Boost Clock 

Thermal Throttling 
Performance drops when graphic card gets heated up.

Good cooling system is mandatory.

Memory clock and Bus clock.


CUDA is the NVIDIA Language 

DDR 4 were 24 nanometer chips.

DDR 5 are 14 in AMD for and 16 in NVIDIA 

AMD are built in UK slightly cheaper 
NVDIA are built in Taiwan  not China are bit expensive.

Manufactured in 
TSMC
Taiwan Semiconductor Manufacturing Company
Samsung
Global Founderis.

How Graphic Cards work?
36 trillions calculations a second.
Video Games
Bit Coin Mining
Neural Net Working 
AI

CPU has 24 Cores
Graphic Card had 10,000 cores.

PCB
Printed Circuit Board where all the components are mounted on.

The components are

Memory is GDDR 4 and 5

GPU

CUDA cores
Simple algebraical calculations

Tensor Cores for 3 point matrixes

Ray tracing algorithms  completely new terminology to me.
I started with 512 MB RAM and worked with 1GB RAM for over 2 decades.

My NUC with integrated graphic card has 8GB RAM and runs Debian Gnome 12.7.0.

What a turn around for an old guy like me.
Now elections are over I am back to computer logics and my books.

My book on "Linux Fundamentals" will have a chapter on current technology.

Other components are

Power Supply
In put is 12 volts but out put is 1 volt or zero.
Computers works on 1 one and 0 zeros.

Various ports

Graphic slot that mounts on the motherboard

GPU

GDDR 6 and 7 Memory Chips feed in the calculations to the GPU in Embarrassingly Parallel Computations which are necessary for Video gaming.

Why I do not use a Mobile

Why I do not use a Mobile

Why I do not use a Mobile

 
Mind you I have a land phone.

Read this in tandem with attention deficit (new syndrome defined by me) below.
 
This is something I posted elsewhere.

I have 100 or more reasons why I do not have or use a cellphone.

I will list them as they come to my mind but not in any order of priority.
 
As an intern I hated all calls mobile included since it meant, a batch of new arrival of small kids who have arrived in absolutely appalling condition.

Some of them fitting due to low blood sugar nearing zero.
 
In fact, I had 8 to 10 kids whose blood sugar and CSF sugar levels were down to zero.
 
The government at that time told the public it was due to encephalitis and I proved them wrong even without my medical registration completed. 
I used to take blood samples to Medical Reaserch Laboratory in Borella and come the next week to collect the reports.

This is during Sirima and NM and Covinn time.

Then in 6 months later when I went to collect my own data they had disappeared mysteriously from, medical records.
 
Then, what I did subsequently, I have to pen down on a latter date of my life, nearing my death.

One thing was sure, leaving this messy Health Service and I decided to leave the Public Health Service for good and I was glad I did that and if you read Dengue Dilemma elsewhere, in my writings, one can easily guess it.
 
It has deteriorated in quality even though, it has expanded.
 
As a doctor, I hated bad news by telephone.
 
We rarely hear good news when on duty.
 
Later in life when cellphone came, I believed in CPP (Calling Party Pays) and flatly refused a cellphone.

It is a public nuisance.
 
It is a nuisance when the cellphone owner has switched it off when one really need him / her.
 
When you travel on a public transport one cannot have a snooze to drown the inconvenience with frequent telephone interruptions. 
 
I love silence in public places
 
Even though, I don’t use it, I have to foot the bill (kid's telephone bills).
 
 No work get done in public officers.
 
They are busy answering their private calls of nature and it is more frequent than the real call of nature.
 
It is cheaper to redirect a message by email that should end up as a junk or a piece of gossip.
 
We use it for gossip not for creative work. 
 
It is private enemy number one when you own the bank or telephone company a small sum in arrears and the reminders by them costs more than the amount you actually own them.

I think you got the picture correct. 

I think it is enough for today but I will add more on future date when I run short of a topic to write. 
 
Memory and Gadgets
Attention Deficit Related (Mundane gadgets like tablets) to Technology Addiction.

Many years ago, I posted an article on the web regarding memory specially in reference to Buddhist Monks of yesteryear (
not today´s TV acting MahaMewna Type) and all the points except my assertion on Mediation Practice (focused attention on the present moment) was copied by an Author of the Scientific American Publication and most recently by another author.

This is one reason, I thought of writing a few books before my memory fails by default and due to old age.

It is rather loss of short term memory and now I have coined a fancy Medical Term.

Few years ago (I still do not take a note or reminder but devised a 24 hour simple protocol to enhance day to day activity), I noticed lapses in my memory and got activated.

1. I won´t use the telephone but buy a cheapest cellphone when I go abroad and drop it to a bin at the airport (this is the biggest handicap and in the middle of your work, one may give a call with a low priority-gossip related call). 

When I tried to do that long time ago, one of my relatives in Singapore asked for it and duly obliged. Another one I used for sometime gave it free to a classmate of mine. 
His son had lost his expensive cellphone when travelling to Colombo by bus.

Who Cares for an expensive cellphone
.

Thank God, one can switch off the cell, then what is the use of a telephone, if it is not doing it's job, simply transfer a message.

I use my land phone at my discretion since I pay the bill.
Not even the Telecom (delay in payment) or the a bank officer can break that law and break into my freedom.
 
2. Won´t sit in front of the TV and watch web videos unless it is related to animals, especially Elephants.

One Baby Elephant dead was trapped in a tree in this country
.

There is a video of an elephant mum protecting its young baby from hyenas (we have to protect the young one's from political hyenas and some
rabid monks in saffron cloth).

3. I live with living things, the dog, fish, and plants, including water plants.

All three will die if I do not have some simple protocol, not so rigid but to remind me that there are other lifes on this planet, 
in relation to me.

Fortunately fish can go on for 10 days without food
.

If neglected any longer toxic algae will kill them.

A dog will die within three days without water, if there is no care giver.

Believe it or not Dogs never use telephones even in an emergency.
They only BARK.

My dog in particular will start barking for no reason when I am on the phone.
 
He wants me to stop talking quickly and he has not got a degree in economics but he knows how to cut my telephone bill.
 
The garden will go to wilderness in no time.

All these little things one has to be mindful, however busy one is in day to day life, even if one has servants to look after these odd jobs.

They will never do them right in my experience.
 
4. Use the computer and the email productively.

5. Keep in touch with family and family friends in person.
When one sees a friend, just stop for a few minutes and greet them and have some empathy.
You may not see them again could even be run over by a vehicle driven by a fast track lumpen with a cellphone in hand.
 
I am predicting now with Facebook and low priority web videos, the present young generation will hit a very low point, in their middle age with Attention Deficit and I am going to coin the Medical Term, Attention Deficit Related to (Mundane gadgets like tablets) Technology Addiction (AD-R-TA- RTA stands for Road Traffic Accidents and some of these gadgets may trigger an accident on the road too).

How to become a Successful Politician

How to become a Successful Politician
 
I was getting totally fed up of all politics both local and global, mainly because it effected my writing habits, especially books.
I was particularly interested in Election in USA.
Local election, I knew the outcome well in advance and the total lack of political will of the opposition.
They were all geared up for the big post and spent all their money, resources and time, on that post.

Burnt out Syndrome.

They forgot that in parliamentary democracy what is important is vibrant opposition.
I say our citizen's are stupid enough to give 2/3rd majority.

I was particularly interested in ousting corrupt War Mongering Democrats.
It has come good but very soon MIC with it's might will turn Donald Trump into War Footing, starting from Israel to begin with.

Ukraine has become a dead end for Americans but EU guys with twisted tounge will continue to carry the War Flames.

This was of course a dream 
This is the Topic of my next book, too.
It has some caveats.
Book won't be published but only on digital form.
If any body wants a copy FREE, he or she has to read one of my old books and send me an email to the email address given, in that book in the last page of the book.

Let me say, it is a Yahoo Mail opened well before Gmail.
 
I have never got an email in respond to any of my books published, either due to nobody has read it/ them at all or s/he has not read the last few pages.

Then they have to find this blog site (I have not given any clues) and quote the latest blog piece to qualify for free book.
Idea is to promote this site and not my books.

Let me say a few words to the guys who were selected to the Parliament I Ceylon.
 
1. Will they pass a bill to cancel pensions for MPs?
 
This is to save money for the coffers to begin with.
This has to be done before they take over the official residences of past presidents.

I bet that they cannot get this piece passed in the present parliament.
 
Reasons are many.
 
a) The privileges for a MP far exceed any CEO in America.
 
b) When they see the comforts provided to the MPs in the present parliament, no one would blame Pxxxxx Nanayakkara (who lost his seat for the first time and he was a List MP not answerable to any average citizen. He brought filth to the parliament for the first time) his crave and stamina to last so long without repugnance.

c) They will never get 2/3rd majority for this bill.
At worst they would say they would introduce that this  "no pension for MPs" in the next constitution.
I will leave at that.

To read about my dream one has to read my digital book.

This book is given free to anybody including present parliamentarians to promote Total Digitization of Government Activities. 

This government promised digitization and I want to see how they would do it, successfully.

I will not dish out or volunteer how it can be done being a fully digital man for ages.
