ABY inner product AMI: volume size

Hi, I cannot deploy instances for the ABY inner product protocol since the disk is too small (see below for a traceback). In deploy_instances() the disk image is fixed to a size of 20 G: https://github.com/cryptobiu/MATRIX/blob/92cc27b504d4e7fa48dedfe0194e2633b375bc8e/Deployment/aws_deploy.py#L144 The error message says that the snapshot for the AMI needs at least 100 G. Is an image that big necessary?
