Supported APIs
This section describes the supported APIs and includes the following topics:
• MVAPICH MPI
• uDAPL
• Intel MPI
• HP MPI
API refers to software in the networking layer in user space.
MVAPICH MPI
MPI is a standard library functionality in C, C++, and Fortran that can be used to implement a
message-passing program. MPI allows the coordination of a program running as multiple processes in a
distributed memory environment. This document includes setup and configuration information for
MVAPICH MPI. For more information, see Chapter 7, “MVAPICH MPI.”
uDAPL
uDAPL defines a single set of user-level APIs for all RDMA-capable transports. The uDAPL mission is
to define a transport-independent and platform-standard set of APIs that exploits RDMA capabilities
such as those present in IB. For more information, see Chapter 6, “uDAPL.”
Intel MPI
Cisco tests and supports the SFS IB host drivers with Intel MPI. The Intel MPI implementation is
available for separate purchase from Intel. For more information, visit the following URL:

HP MPI
Cisco tests and supports the SFS IB host drivers with HP MPI for Linux. The HP MPI implementation
is available for separate purchase from Hewlett Packard. For more information, visit the following URL:
