TCP

Compile

> make

Server-side run

Lock file version
> ./server-lock <file-name>
No lock file version
> ./server-nolock <file-name>

file-name : Specify the file name to log

Client-side run

> ./client <server-name> <client-name> <repeat-count>

server-name : Server-side's name or IP
client-name : A name that can identify the client that is running this program
repeat-count : Number of times to repeat message sending and receiving

proccess

Compile

> make

Run

> ./prod2cons <buffer-size> <number-of-producer> <number-of-consumer> <repeat-count>
Can confirm parallel access of producer process and consumer process of ring buffer which is shared memory.

Do the time taken from process creation as the final output as follows.
<Real time>,<CPU time>

thread

Compile

> make

determinant

> ./determinant <matrix-size> <number-of-thread>

prod2cons

> ./prod2cons <buffer-size> <number-of-producer> <number-of-consumer> <repeat-count>

janken

Compile

> make

parent

> ./parent
Open port 20000

child

> ./child <server-name> <CPU-name>

server-name : Name of server on which parent program is running
