from round robin to best-fit
Hi all,
I am trying to develop a mechanism to know which machine can handle a user job (by providing his Requirements) for now I wrote this method but it is a Round robin, I am trying to modify it to a best-fit algorithm can anybody give me tips about how should I begin?
publicstatic String canDo(Resources userReq,Hashtable hash){
//getResourceInfo() is a method that store the machine name
//and thier resources(cpu,memory,disk) in a hashtable
Hashtable resourceInfo = connectData.getResourcesInfo();
Enumeration en = resourceInfo.keys();
String status ="";
String machineName;
Resources machineRec;
while(en.hasMoreElements()){
machineName = (String)en.nextElement();
status ="the following machine has been allocated to you: "+machineName;
//resourc
machineRec = (Resources)resourceInfo.get(machineName);
if(machineRec.getCpu().getCpuIdle()>=userReq.getCpu().getCpuIdle())
if(machineRec.getMemory().getFreeMemory()>=userReq.getMemory().getFreeMemory())
if(machineRec.getDisk().getFreeSpace()>=userReq.getDisk().getFreeSpace()){
break;
}
}
return status;
}
