+Sample Application Tests: Multi-Process
+=======================================
+
+Simple MP Application Test
+==========================
+
+Description
+-----------
+
+This test is a basic multi-process test which demonstrates the basics of sharing
+information between DPDK processes. The same application binary is run
+twice - once as a primary instance, and once as a secondary instance. Messages
+are sent from primary to secondary and vice versa, demonstrating the processes
+are sharing memory and can communicate using rte_ring structures.
+
+Prerequisites
+-------------
+
+If using vfio the kernel must be >= 3.6+ and VT-d must be enabled in bios.When
+using vfio, use the following commands to load the vfio driver and bind it
+to the device under test::
+
+ modprobe vfio
+ modprobe vfio-pci
+ usertools/dpdk-devbind.py --bind=vfio-pci device_bus_id
+
+Assuming that a DPDK build has been set up and the multi-process sample
+applications have been built.

+Client Server Multiprocess Tests
+================================
+
+Description
+-----------
+
+The client-server sample application demonstrates the ability of Intel� DPDK
+to use multiple processes in which a server process performs packet I/O and one
+or multiple client processes perform packet processing. The server process
+controls load balancing on the traffic received from a number of input ports to
+a user-specified number of clients. The client processes forward the received
+traffic, outputting the packets directly by writing them to the TX rings of the
+outgoing ports.
+
+Prerequisites
+-------------
+
+Assuming that an Intel� DPDK build has been set up and the multi-process
+sample application has been built.
+Also assuming a traffic generator is connected to the ports "0" and "1".
+
+It is important to run the server application before the client application,
+as the server application manages both the NIC ports with packet transmission
+and reception, as well as shared memory areas and client queues.
+
+Run the Server Application:
+
+- Provide the core mask on which the server process is to run using -c, e.g. -c 3 (bitmask number).
+- Set the number of ports to be engaged using -p, e.g. -p 3 refers to ports 0 & 1.
+- Define the maximum number of clients using -n, e.g. -n 8.
+
+The command line below is an example on how to start the server process on
+logical core 2 to handle a maximum of 8 client processes configured to
+run on socket 0 to handle traffic from NIC ports 0 and 1::
+
+ root@host:mp_server# ./x86_64-native-linuxapp-gcc/examples/dpdk-mp_server -c 2 -- -p 3 -n 8
+
+NOTE: If an additional second core is given in the coremask to the server process
+that second core will be used to print statistics. When benchmarking, only a
+single lcore is needed for the server process
+
+Run the Client application:
+
+- In another terminal run the client application.
+- Give each client a distinct core mask with -c.
+- Give each client a unique client-id with -n.
+
+An example commands to run 8 client processes is as follows::
+
+ root@host:mp_client# ./x86_64-native-linuxapp-gcc/examples/dpdk-mp_client -c 40 --proc-type=secondary -- -n 0 &
+ root@host:mp_client# ./x86_64-native-linuxapp-gcc/examples/dpdk-mp_client -c 100 --proc-type=secondary -- -n 1 &
+ root@host:mp_client# ./x86_64-native-linuxapp-gcc/examples/dpdk-mp_client -c 400 --proc-type=secondary -- -n 2 &
+ root@host:mp_client# ./x86_64-native-linuxapp-gcc/examples/dpdk-mp_client -c 1000 --proc-type=secondary -- -n 3 &
+ root@host:mp_client# ./x86_64-native-linuxapp-gcc/examples/dpdk-mp_client -c 4000 --proc-type=secondary -- -n 4 &
+ root@host:mp_client# ./x86_64-native-linuxapp-gcc/examples/dpdk-mp_client -c 10000 --proc-type=secondary -- -n 5 &
+ root@host:mp_client# ./x86_64-native-linuxapp-gcc/examples/dpdk-mp_client -c 40000 --proc-type=secondary -- -n 6 &
+ root@host:mp_client# ./x86_64-native-linuxapp-gcc/examples/dpdk-mp_client -c 100000 --proc-type=secondary -- -n 7 &
+
+Test Case: Performance Measurement
+----------------------------------
+
+- On the traffic generator set up a traffic flow in both directions specifying
+ IP traffic.
+- Run the server and client applications as above.
+- Start the traffic and record the throughput for transmitted and received packets.
