Dear Uri argaman, Our service(materials square) is providing user interface and cloud HPC for QE.
Our service uses the AWS EC2 instances(c5), and we’ve found that performance is similar or superior to the on-premise HPC. However, we also found that MPI performance dropped when we used c5.9xlarge instance. so I recommend to use top-level instance in the instance group(i. e. c5.18xlarge) Could you provide your AWS environments(compiler, instance type, AMI,..)?
