You Need the Absolute Highest Possible Network Performance for a Cluster

question 424

Multiple Choice

You need the absolute highest possible network performance for a cluster computing application. You already selected homogeneous instance types supporting 10 gigabit enhanced networking, made sure that your workload was network bound, and put the instances in a placement group. What is the last optimization you can make?

• A) Use 9001 MTU instead of 1500 for Jumbo Frames, to raise packet body to packet overhead ratios.
• B) Segregate the instances into different peered VPCs while keeping them all in a placement group, so each one has its own Internet Gateway.
• C) Bake an AMI for the instances and relaunch, so the instances are fresh in the placement group and do not have noisy neighbors.
• D) Turn off SYN/ACK on your TCP stack or begin using UDP for higher throughput.
