#cluster
cluster is template for creating serverfarm. This is allowing to communicate in between them. One can either broadcast the message or send to individual server lying within cluster.
#Usage
go get github.com/mgkanani/cluster
go install github.com/mgkanani/cluster
(go to cluster directory i.e. github.com/mgkanani/cluster and run below to see msgs' summary).
go test
#To customise parameters ###Modify config.json
To add more servers with different port and pids. Pids must be in strictly order means 1,2,3,4 but not 1,2,4,7. The order 1,4,3,2 will work perfectly.
###Modifying cluster_test.go
for Testing update values of variables total_servers count , and total_msgs.
for testing the msgs tranfer of size > 60000 bytes uncomment lines 48,57 and comment line 49.
#Default configurations:-
Total Servers :- 10
ipaddr:127.0.0.1
ports :-12345,12346,12347,12348 ... 12354
Pids:-1,2,3,4 ... 10
total_servers=10(linenum 18 in file cluster_test.go),
total_msgs=300(linenum 19 in file cluster_test.go)
#Experiments:-
totalnumber of servers:-10
total msgs each Server broadcasts :-300
msg_size:-65K bytes
###output
total msgs received at PID - 1 :- 2700 sent:- 300
total msgs received at PID - 2 :- 2700 sent:- 300
total msgs received at PID - 3 :- 2700 sent:- 300
total msgs received at PID - 4 :- 2700 sent:- 300
total msgs received at PID - 5 :- 2700 sent:- 300
total msgs received at PID - 6 :- 2700 sent:- 300
total msgs received at PID - 7 :- 2700 sent:- 300
total msgs received at PID - 8 :- 2700 sent:- 300
total msgs received at PID - 9 :- 2700 sent:- 300
total msgs received at PID - 10 :- 2700 sent:- 300
