Entanglement — QComputing, EPR, and Bell

Mycket bra o intressant om fysiken o matematiken bakom quantum entanglement samt hur en quantum dator fungerar och dess algoritmer. Från MIT opencourse Quantum Physics 1

To decrease the CPU demands for an application

Save the bash script below in a file called cpulimit.sh and give it executions rights with chmod.

-----CODE START----

#! /bin/bash

# Description:

# 

# Tested on Macos and Mac OS X.

# If you want to decrease the CPU demands for an application

# you can use this very simple and ugly "hack". 

# I use it when I e.g convert videos on my MacBook Pro, compiling things, ...

# to prevent it from getting to warm. Even if the CPU is IDLE this simple hack

# will prevent the application to use the CPU during Sleep Time

# (in contrast to renice/nice commands which will take all IDLE time). 

# 

# Hint: To get the PID (Process ID), first run command top -u in one Terminal window.

# 

# Usage: ./cpulimitrob.sh

# 

#

#

echo "Which process ID (PID)? "

read pid

echo "Sleep time in seconds? "

read sleeptime

echo "Run time in seconds (e.g 0.5 or 1 …)? "

read runtime

i=1

dot=.

while true

do

if [ $i -eq 1 ]

then

kill -SIGSTOP $pid

sleep $sleeptime

i=0

else

kill -SIGCONT $pid

sleep $runtime

i=1

fi

echo -n $dot

done
