AWS AMIs are either Para Virtual Machine (PVM) or Hardware Virtual Machine (HVM) images. All of the AMIs from Oracle are currently only PVM-based. Therefore, they will not run on cluster compute or i2 instance types.
More information on HVM-based instances types:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using_cluster_computing.html#concepts_cluster_compute_hvmAMI
http://aws.amazon.com/ec2/faqs/#Does_use_of_Cluster_Compute_Instances_differ_from_other_Amazon_EC2_instance_types
Currently, the new i2 instance types are HVM only:

If you are looking to run Oracle solutions on Oracle Enterprise Linux and require more then 68 GB of memory, you would have to run on hs1.8xlarge (117 GiB) as all other instance types with more then 68 GB are HVM. See more here: http://aws.amazon.com/amazon-linux-ami/instance-type-matrix/
