A small bio-technical company is interested in implementing a 32-node Linux cluster.They have developed their own software that allows all of the nodes to work on the same problem at the same time.The application requires messages to be passed between the nodes.Each node will require access to a shared storage pool of around 500GB. To identify the inter-process communication （IPC） networking requirements， which of the following is the most appropriate question to ask？（）

• A、Is the network capable of using 4x or 12x infiniband？
• B、Will remote shell （rsh） be enabled for remote process initiation？
• C、What are the data transfer requirements for inter-node message passing？
• D、What type of data is being sent across the inter-process communication network？
