Load Balancing Dan Priece

What is Load Balancing? Distributed computing with multiple resources Need some way to distribute workload Discreet from the user Increase:  Reliability  Efficiency

Uses Internet Servers Distributed applications  Render Server By means of hardware or software

Strategies Static Balanced before parallel code execution Quasi-Dynamic  Infrequent changes to balance  Save computational time Dynamic  Frequent changes  Frequent recalculations of balance

Implementations Random  Simple  Does not guarantee even balance Round-Robin  Even balance  Does not work well with varying spec systems Weighted Round-Robin  Even balance  More overhead

Implementation in Render Server Use Weighted Round-Robin approach  Dynamic  Course-Grained  Weighted by system factors CPU Load System Specifications Network Speeds
