parallel computer

Question 1

how to increase the rechner

Answer 1

cpu frequency
multi threading
2cpu on the same chip
coprozessoren
long pipeline

Question 2

What is Multithreading?
and what are the 3 types of multithreading

Answer 2

technique where multiple threads(light execution within a process) are used for parallel execution
with cycle
fine granular- every clock cycle it changes, reduce latency, switching
big granular- changes when instruction blocked or waiting recourses- lesss throughput

Question 3

multi processor system

Answer 3

-same memory
same betriebssysteminstanz.
good
easy to program
nachteil
doesnt scale well

Question 4

multi computer

Answer 4

ever< has its own memory, communicate over sent messages
all cpu has its own betriebsysteminstanz
vorteile
scalierbar , scientifical
nachteil
administration

Question 5

Common Mmemory

Answer 5

Problem-> access same bit.who writes last
strict consistence
synchronisation,
same order

Question 6

sequential consistance

Answer 6

keeps the order of operation with random choice of operating time
global reihenfolge
each cpu do its owhn befehl

it is random

Question 6

processor consistencx

Answer 6

Idea of Processor Consistency
Preserve Local Order:
Each processor maintains its local order of memory operations.
Different Global Orders:
Different processors can see different global interleavings of memory operations.
