#5 the feelings i need to remember everyday

How do i wake up early in the morning ?

Okay, here’s the truth.

5:30 AM,

I opened up my eyes lying in bed,looking at ceiling. No, strictly not because of Alarm went off ten times.And surely not because i had to take dump or pee.Honestly, i opened my eyes in panic.

5:40 AM,

I went on terrace to fade away these panic situation out off my head and started listening to hard music.

Linkin Park,

Breaking Benjamin,

3 Doors Down,

Skillet,

”it’s not working”,i felt and tuned to motivational speech.

5:50 AM,

All the while listening to how jobs did achieve his goals, how gates become successful,what message did abdul kalam gave to youngsters,how they lead their ways out of from nothing to something worth remembering made blood rush within my body with the lightning speed.

I started throwing punches, moving my body in all possible directions.After few minutes of vigorous jumping,squeezing i calmed down myself.I was breathing heavily.

I was facing the horizon and breathing like i was gonna die, i whispered to myself,”Now i’m feeling alive”.

I was facing the horizon like the king of jungle who had won the fight.I started feeling better.

“Not just better but like a Ferrari started its engine to all of its limits, like a Mercedes is standing and showcasing her beauty and roaring or like a Tesla is encouraging her uniqueness.”

5:55 AM,

Horizon started to glow.

“ the sun is rising, it’s getting started “,i murmured to myself again.

I wore my shoes and went on running.

Everyday, while i’m in deep sleep i dream of my goals, knowing getting everything is the best feeling but i know it’s just a dream, not an actual reality.

Realising, it’s just a dream makes me panic.

And to make my dreams come true, i have to wake up even before the sun rises.

#4 Research problem statement

Current problem statement i am working on is as follows:

I will give an example of graph dataset to understand problem statement.

Graph has V (vertices) and E(set of edges).

ex. livejournal has  #V = 4.8M, #E=57.7M (M stands for Million) Size=597MB/1.1GB (unweighted/weighted)

1GiB = 1024^3 B

1GB = 1000^3

Now fastest supercomputer today as of 2022 is Japnese Fugaku by Fujitsu.

It is exascale that means it can compute 10^18 FLOPS (1 exaFLOPS).

It has around  158k nodes and 32GiB per node of SDRAM memory. (roughly 34.35GB)

Now these implies cache will be lot less than memory capcity. L1-d=64KiB, L2=8MiB.

Point is CPU needs data in cache hierarchy and memory. Farther away the data, more time will be spent on bringing requested data closer to CPU. To compute any graph algorithm on given dataset size, in no way it will always present in cache hierarhcy at the same time (untill now these is our regular problem in computer architecture).

Now, Graphs are interesting and adds more complexity here. Graph accesses are very random. Let's say your cache can hold only 100 nodes currently, upon request to 10^5 node number, you will have to make space to accomodate memory block containing these requested node number. And lets say you evicted cache line containing node 1. And at very next request from cpu, node 1 is requested. But right now it is not in cache. May be it is not even in DRAM. We will have to request it from storage. Hence adds extra latency. So these randomness is not predictable to make use of prefetched data. And these is the problem, graph computation becomes more costly. 

Hope you enjoyed it.

I will try to post it more. If you find information in blog to be impricise please help me improve.

That's it for today.

I am looking for research position in computer architecture in industrial/academic labs.

Please let me know if you or someone in your contact is hiring.

Thank you,

#3 songs i like

1.Feeling of being by Songwriters: Lucy Schwartz / Sally Mary Seltmann
"Bet you if you sink
You'd swim a little further
And I bet you if you cried
You'd understand me better
So I take a little time just sailing down the river
And I'm throwing out my line to see 
if I can catch the feeling of being"
2.Shape Of My Heart by Sting / Dominic Miller
Well for these song, i loved music. 
It is silent, makes me feel calm.
3.Simple Man by Shinedown 
"Mama told me when I was young
Come sit beside me my only son
And listen closely to what I say
And if you do this it'll help you
Some sunny day oh yeah"

4.Crossfire by Stephan songwriters: Grahm Andrem Muron, Stehpen Michael Swartz
"Can I trust what I'm given
When faith still needs a gun
Whose ammunition
Justifies the wrong?
And I can't see
From the backseat
So I'm asking from above
Can I trust what I'm given
Even when it cuts?"
5. Never too late by Three Days Grace songwriters Adam Gontier, Brad Walst, Gavin Brown, Naomi Brewer, Neil Sanderson
"This world will never be
What I expected
And if I don't belong
Who would have guessed it?
I will not leave alone
Everything that I own
To make you feel like it's not too late
It's never too late"
6. Make a move by Icon for hire songwriters: Jump Arief, Bloomer Ariel
"Cause everybody's so scared
We don't wanna go there
We don't wanna make a move
We got all our lives to lose
Screaming in the dark while we just play our part
I'll play right along like I don't know what's going on
Somebody make a move
Somebody make a move
Please, somebody make a move
We all know, we all know what's going on"
7. For the glory by All good things songwriters: Jordon Kristopher Terrel, George Aruthur Regan, Elizabeth Hooper, Randall Brent Cooke, Andrew Bojanic, Dan Murphy, Phoebe Ogan
"You're the tracer, I'm the eraser, I'll ruin your record
I'm back here to break ya
I cut like a razor so call the trophy engraver
I'm gonna get it, wait 'til I win it, God I'm so glad to be in it
Can't wait to say that we did it, this is my life and I live it
Ready to give it my all when you
Fall back, taking advantage of all that
Game is on average, you're so bad
Playing shorthanded, your team scratched
Time to assess all the damages, I know that you couldn't handle this
It takes a man to stand up to the king
And unfortunately you're in bandages"

#2 Career Challenge

 These is about career decision i took a year ago. It was to join for MS by Research program through GATE 21 exam. Score wasnt good enough to get into top instituion. Thought i will go for second attempt. But then doing that without job at hand wasnt good. I gave lot of interviews went on to final talks, but then never received anything from organization. It was very difficult phase. Yet with some valid GATE score i realized i could go for research fellow position at any institute for research project. Thankfully i got that. At the same time i received good news from very good companies but then i was already onboard and denied those mails. So far, research work is going well, here and there few roadblocks i faced but eventually is going well. Problem is now timelimit. I have like 5 months in hand before funding would be cut. (challenge)

Plan was to based on these exprience go for MS/Phd abroad. I need to work up my ass off. Side by side find a research potential area while doing relevent courses. Its been 5 months now already.

Oh and before that i was bitten by startup bug in final year of my bachelors, and worked for 2 years with a startup orgnization at end i felt not working in the potential domain to learn market gap and have my own thing to start, also found myself very limitted with expertise on stuff i did worked on. Hence idea of MS by Research to develop that expertise.

#1 First Post: Introduction

 Hi, I am Pravesh S. Jamgade. I am a Software Engineer by profession. Through these blog i want to keep myself winded up for my me time. I intended to post on every week on any topic say from hobby, books, mediation, politics, jokes, stories, project ideas, learning journey, career decision etc.

I want to use labels for such topic wise post. Intially i was thinking to post on technical stuff i am learning.

so why not just label as tech or non-tech. but i also want to write politics,meditation,exercise etc.

ok, i will use following tags.

tech : computer-architecture, problem-solving, ideas, 

non-tech:  story, books,  politics, self-improvement (for meditation, exercise), lyrics

i will see, thats it for today on indtroduction.
