Karakteristik Thread

Karakteristik Thread
Proses merupakan lingkungan eksekusi bagi thread-thread yang dimilikinya. Thread-thread di satu proses memakai bersama sumber daya yang dimiliki proses, yaitu :
· Ruang alamat.
· Himpunan berkas yang dibuka.
· Proses-proses anak.
· Timer-timer.
· Snyal-sinyal.
· Sumber daya-sumber daya lain milik proses.
Tiap thread mempunyai property independen berikut seperti :
· Keadaan (state) eksekusi thread (running, ready dan sebagainya).
· Konteks pemroses. Thread dapat dipandang sebagai satu PC (program counter) tersendiri independen di satu proses.
· Beberapa penyimpan static per-thread untuk variable-variabel local.

Struktur Sistem Operasi Multiprocessor

System operasi serupa multiprogrammed uniprocessor. System operasi multiprocessor lebih kompleks karena terdapat banyak pemroses yang mengeksekusi task-task secara kongkuren. System operasi multiprocessor harus dapat mendukung eksekusi banyak task dan mengeksploitasi banyak pemroses untuk meningkatkan kinerja.
Struktur system operasi multiprocessing, antara lain :
1. Separate supervisor
Semua pemroses mempunyai kopian kernel, supervisor dan struktur data sendiri, menanggapi interupsi-interupsi pemakai yang berjalan di pemroses itu. Terdapat struktur data bersama untuk interaksi di antara pemroses-pemroses. Pengaksesan diproteksi menggunakan mekanisme sinkronisasi :
· Tiap pemroses mempunyai perangkat I/O dan system file sendiri.
· Terdapat sedikit coupling diantara pemroses-pemroses.
· Tiap pemroses bertindak sebagai system otonom dan independen.
> Keunggulan :
· Dapat degradasi secara perlahan dalam menghadapi kegagalan pemroses karena hanya terdapat sedikit coupling diantara pemroses-pemroses.
> Kelemahan :
· System sulit melakukan eksekusi pararel satu task tunggal (yang dipecah menjadi subtask-subtask dan menjadwalkan subtask-subtask di banyak pemroses secra kongkuren).
· Tidak efisien karena supervisor, kernel dan struktur data direplikasi di tiap pemroses.
2. Master-slave
Satu pemroses disebut master, bertugas memonitor status dan memberikan kerja ke pemroses-pemroses lain, slave. Slave-slave dipandang sebagai pool sumber daya yang dijadwalkan master. Pemroses-pemrose slave mengeksekusi program-program aplikasi.
> Keungulan :
· Efisien.
· Implementasi (sinkronisasi pengaksesan variable, dan sebagainya) mudah karena system operasi dieksekusi di satu pemroses tunggal.
> Kelemahan :
· Sangat bergantung pada pemroses master.
· Master dapat mengalami botlencek dan berkonsekuensi tidak menggunakan pemroses-pemroses slave secara penuh.
3. Symmetric
Semua proses otonom dan dipandang identik. Terdapt satu kopian supervisor atau kernel yang dapat dieksekusi semua pemroses secara kongkuren.
> Masalah :
· Pengaksesan kongkuren struktur data bersama perlu dikendalikan agar terjaga intergritasnya.
> Solusi :
· Cara paling sederhana adalah memandang seluruh system operasi sebagai satu critical section dan hanya memungkinkan satu pemroses mengeksekusi system operasi di satu waktu. Metode ini disebut floating master karena dapat dipandang sebagai konfigurasi master-slave dimana master di-apungkan/diangkat dari satu pemroses ke pemroses lain.
> Keunggulan :
· Paling fleksibel dan berdaya tahan tinggi.
· Memungkinkan eksekusi satu task tunggal secara pararel.
· Dapat mendegradasi secara perlahan dalam menghadapi kegagalan.
· Penggunaan sumberdaya sangat efisien.
> Kelemahan :
· Perancangan dan implementasi paling sulit.

IN ACTION THE DIVA'S

lirik the saturday - issues

Ohhh Yeah

Sometimes
I Feel like I’m going out of
My mind,

Boy the way you do me is a
damn crime,

But then you smile at me
and its all right,

With you there aint nothin' in between,

Every time that I walk out the door,
Tell myself I can't take it no more,

There’s a part of me won't let you go
Keep saying yes when my minds saying no,

Chorus:
Me and my heart we got issues,
Don’t know if I should hate you or miss you,
Damn, I wish that I could resist you,
Can't decide if I should slap you or kiss you.
Me and my heart we got issues, issues, issues.
We got issues, issues, issues.

Its so wrong, boy you leave me hangin' for so long,
You empty out my love until its all gone,
You change the words but still it's the same song,
I’m tired of the melody.

Change my number and throw out your clothes,
But my feelings for you, it still shows,
I keep building the walls round my heart,
But then I see you, and it all falls apart...

Chorus:
Me and my heart we got issues,
Don’t know if I should hate you or miss you,
Damn, I wish that I could resist you,
Can't decide if I should slap you or kiss you.
Me and my heart we got issues, issues, issues.
We got issues, issues, issues.

Why fight it, cant hide it
Truth is I think I like it,
Confusion, illusions
Still I don’t know which way to go….


Chorus: (x2)
Me and my heart we got issues,
Don’t know if I should hate you or miss you,
Damn, I wish that I could resist you,
Can't decide if I should slap you or kiss you.

Me and my heart we got issues, issues, issues.
We got issues, issues, issues.

Me and my heart we got issues, issues, issues
We got issues, issues, issues,
We got issues, issues, issues
We got issues, issues, issues

Me and my heart we got issues
Don’t know whether I should hate you or miss you.

All you have to do is only believe in me
I like you a lot, I can't let you slip

From those fixed images, it's okay

[Onew] Break out (Hey!) (x4)
Ring ding ding ding ding
Dong dong dong dong

[Jonghyun] Honestly, I'm nervous
About how you see me
[Taemin] Maybe, maybe
I don't know if you have a good impression of me
[Onew] If it's like this, I can only be restless
[Jonghyun] I can't turn back

[Onew] Complicate girl
([Minho] Never answer with a no)
[Jonghyun] I'm a decent guy
([Taemin] I don't know if I'll go crazy)

[Key] Don't be silly, girl

I don't need anything else

lirik lagu Shinee - lucifer

Shinee -LUCIFER

Even if I try to avoid you, I can't find a place to hide
I'm trapped by you, who I can't even deny
If it was love, if you really loved me, don't do this to me
Her whisper is the Lucifer

*If you tie me down and trap me
Then the love is also tied down
The future is also tied down
It can't grow anymore
Freely empty yourself and look at me
I'll fill you only, I'll completely fill you only

Your undeniable spell is the Lucifer
Your undeniable magic is the Lucifer
When I approach you
With your angelic face
Say the reason you live is for me
Say it

When I first saw you, I stopped for a short time
As if someone was tightly seizing my heart, not letting it go (Still)
You took all, all, all, all, all, all of my heart just like that
You make my heart burn out when you're not here

*If you tie me down and trap me
Then the love is also tied down
The future is also tied down
It can't grow anymore
Freely empty yourself and look at me
I'll fill you only, I'll completely fill you only

Loverholic, robotronic, loverholic, robotronic

The love stories I shared with you
You look towards the same places I do
When we feel that we can't get any more perfect
Only stare at me, you want me more, more, more, more, more, more
Only look at me, you're the center of everything, thing, thing, thing, thing, thing

Since before, something has been wrong, you've been weird
The love I knew left my side, one by one
All I have is you

*If you tie me down and trap me
Then the love is also tied down
The future is also tied down
It can't grow anymore
Freely empty yourself and look at me
I'll fill you only, I'll completely fill you only

I feel like I've become a clown trapped in a glass castle
I dance for you, who will never be satisfied
You look into me openly, touching my brain
I think I've become a fool
I think I'm only getting more and more attracted to you

Loverholic, robotronic, loverholic, robotronic

It's not that I hate you or that I dislike you
It's just that kind of stare is a burden is all
I'm not going anywhere
I've waited like this by only looking at you

Your stare captures me
As the days went by, it became sharper
I'm tired of your obsession
I've been cut a lot, my heart is bleeding
When it's about time for me to pass out
She comes to me like an angel, saying "I love you"
Even though I knew it was really you
You really confused me

*If you tie me down and trap me
Then the love is also tied down
The future is also tied down
It can't grow anymore
Freely empty yourself and look at me
I'll fill you only, I'll completely fill you only

I feel like I've become a clown trapped in a glass castle
Leave me alone, when I'm free, I'll be able to truly love you
Leave me alone, don't make me sick of you
So I can truly look at you

If you tie me down and trap me
Then love is also tied down
The future is also tied down
It can't grow anymore
Loverholic, robotronic, loverholic, robotronic
Your undeniable spell is the Lucifer
