You configured a Cisco usNIC connectivity policy, for a HPC environment.
Which action also must be completed?

A. B. C. D.Explanation.
The Cisco Unified Fabric (CUF) technology provides high-performance computing (HPC) environments with a fast and efficient communication infrastructure through the use of Cisco Universal Computing (UCS) adapters, such as the usNIC adapter.
To fully utilize the benefits of the usNIC adapter, a connectivity policy must be configured. This policy sets the parameters for the adapter's hardware and software configuration, including the maximum transmission unit (MTU) size, priority flow control (PFC), and enhanced transmission selection (ETS).
However, to enable HPC applications to communicate over the usNIC adapter, the appropriate Message Passing Interface (MPI) software must also be installed and configured on the operating system. MPI is a standardized library that provides a platform-independent interface for message passing between parallel processes running on a cluster of computers. It is a critical component of many HPC applications and must be installed and configured correctly for the usNIC adapter to work.
Therefore, the correct answer is D. Install the Intel MPI library environment. The Intel MPI library is a popular implementation of the MPI standard, and it supports the usNIC adapter. It provides high-performance and efficient communication between HPC applications and the usNIC adapter.
Option A, installing an MPI environment in the operating system, is partially correct but not enough to fully enable the usNIC adapter. Option B, downloading and compiling the ring_c application, is not relevant to the question since it does not provide any information about how to enable the usNIC adapter. Option C, mounting the MPI adapter in the operating system, is also not a relevant action since the usNIC adapter is already installed and configured as part of the Cisco UCS system.
