CFD Direct From the Cloud™ (CFDDFC®) — our established platform for running OpenFOAM, ParaView and supporting software in the cloud — is now available on C6i and M6i instances of AWS Elastic Cloud Compute (EC2).  All versions of the CFDDFC product from the AWS Marketplace support C6i and M6i instances, from 9.1 down to 5.3 (corresponding to OpenFOAM versions 9 and below).  Users who launch CFDDFC from the command line interface should update their installation of CFDDFC immediately.

C6i and M6i Instances

The C6i and M6i instances use the 32-core 2.9 GHz (3.5 GHz with turbo-boost) Intel Xeon Platinum 8375C (Ice Lake) processor. With 2 processors per socket, the largest single instances, c6i.32xlarge and m6i.32xlarge, includes 64 cores.  Each C6i instance comes with 4GiB memory per physical core, while the M6i instance has 8GiB.  Therefore, with 0.5 million cells per GiB, one C6i and M6i instance instance could run a simulation with 128 million cells and 256 million cells, respectively.

High Performance Networking and Storage

C6i and M6i instances run at up to 50 Gbps of network speed at the largest instance size, which also supports Elastic Fabric Adapter to provide high speed networking across a cluster of instances. Instances connect to the Amazon Elastic Block Store with speeds of up to 40 Gbps a the largest instance size.
