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. + +Test Case: Basic operation +-------------------------- + +1. To run the application, start one copy of the simple_mp binary in one terminal, + passing at least two cores in the coremask, as follows:: + + ./x86_64-native-linuxapp-gcc/examples/dpdk-simple_mp -c 3 --proc-type=primary + + The process should start successfully and display a command prompt as follows:: + + $ ./x86_64-native-linuxapp-gcc/examples/dpdk-simple_mp -c 3 --proc-type=primary + EAL: coremask set to 3 + EAL: Detected lcore 0 on socket 0 + EAL: Detected lcore 1 on socket 0 + EAL: Detected lcore 2 on socket 0 + EAL: Detected lcore 3 on socket 0 + ... + EAL: Requesting 2 pages of size 1073741824 + EAL: Requesting 768 pages of size 2097152 + EAL: Ask a virtual area of 0x40000000 bytes + EAL: Virtual area found at 0x7ff200000000 (size = 0x40000000) + ... + EAL: check igb_uio module + EAL: check module finished + EAL: Master core 0 is ready (tid=54e41820) + EAL: Core 1 is ready (tid=53b32700) + Starting core 1 + + simple_mp > + +2.

Start up the sample application using the commands outlined in steps 1 & 2 + above. + +2. To load test, send a large number of strings (>5000), from the primary instance + to the secondary instance, and then from the secondary instance to the primary. + [NOTE: A good source of strings to use is /usr/share/dict/words which contains + >400000 ascii strings on Fedora 14] + +Test Case: Test use of Auto for Application Startup +--------------------------------------------------- + +1. Start the primary application as in Test 1, Step 1, except replace + ``--proc-type=primary`` with ``--proc-type=auto`` + +2. Validate that the application prints the line: + ``EAL: Auto-detected process type: PRIMARY`` on startup. + +3. Start the secondary application as in Test 1, Step 2, except replace + ``--proc-type=secondary`` with ``--proc-type=auto``. + +4. Validate that the application prints the line: + ``EAL: Auto-detected process type: SECONDARY`` on startup. + +5. Verify that processes can communicate by sending strings, as in Test 1, + Step 3. + +Test Case: Test running multiple processes without "--proc-type" flag +--------------------------------------------------------------------- + +1. Start up the primary process as in Test 1, Step 1, except omit the + ``--proc-type`` flag completely. + +2. Validate that process starts up as normal, and returns the ``simple_mp>`` + prompt. + +3. Start up the secondary process as in Test 1, Step 2, except omit the + ``--proc-type`` flag. + +4. Verify that the process *fails* to start and prints an error message as + below:: + + "PANIC in rte_eal_config_create(): + Cannot create lock on '/path/to/.rte_config'. Is another primary process running?" + +Symmetric MP Application Test +============================= + +Description +----------- + +This test is a multi-process test which demonstrates how multiple processes can +work together to perform packet I/O and packet processing in parallel, much as +other example application work by using multiple threads. In this example, each +process reads packets from all network ports being used - though from a different +RX queue in each case. Those packets are then forwarded by each process which +sends them out by writing them directly to a suitable TX queue. + +Prerequisites +------------- + +Assuming that an Intel DPDK build has been set up and the multi-process sample +applications have been built. It is also assumed that a traffic generator has +been configured and plugged in to the NIC ports 0 and 1. + +Test Methodology +---------------- + +As with the simple_mp example, the first instance of the symmetric_mp process +must be run as the primary instance, though with a number of other application +specific parameters also provided after the EAL arguments. These additional +parameters are: + +* -p , where portmask is a hexadecimal bitmask of what ports on the + system are to be used. For example: -p 3 to use ports 0 and 1 only. +* --num-procs , where N is the total number of symmetric_mp instances that + will be run side-by-side to perform packet processing. This parameter is used to + configure the appropriate number of receive queues on each network port. +* --proc-id , where n is a numeric value in the range 0 <= n < N (number of + processes, specified above). This identifies which symmetric_mp instance is being + run, so that each process can read a unique receive queue on each network port. + +The secondary symmetric_mp instances must also have these parameters specified, +and the first two must be the same as those passed to the primary instance, or errors +result. + +For example, to run a set of four symmetric_mp instances, running on lcores 1-4, all +performing level-2 forwarding of packets between ports 0 and 1, the following +commands can be used (assuming run as root):: + + ./x86_64-native-linuxapp-gcc/examples/dpdk-symmetric_mp -c 2 --proc-type=auto -- -p 3 --num-procs=4 --proc-id=0 + ./x86_64-native-linuxapp-gcc/examples/dpdk-symmetric_mp -c 4 --proc-type=auto -- -p 3 --num-procs=4 --proc-id=1 + ./x86_64-native-linuxapp-gcc/examples/dpdk-symmetric_mp -c 8 --proc-type=auto -- -p 3 --num-procs=4 --proc-id=2 + ./x86_64-native-linuxapp-gcc/examples/dpdk-symmetric_mp -c 10 --proc-type=auto -- -p 3 --num-procs=4 --proc-id=3 + +To run only 1 or 2 instances, the above parameters to the 1 or 2 instances being +run should remain the same, except for the ``num-procs`` value, which should be +adjusted appropriately. + + +Test Case: Function Tests +------------------------- +start 2 symmetric_mp process, send some packets, the number of packets is a random value between 20 and 256. +summarize all received packets and check whether it is bigger than or equal to the number of sent packets + +1. start 2 process:: + + /dpdk-symmetric_mp -l 1 -n 4 --proc-type=auto -a 0000:05:01.0 -a 0000:05:01.1 -- -p 0x3 --num-procs=2 --proc-id=0 + /dpdk-symmetric_mp -l 2 -n 4 --proc-type=auto -a 0000:05:01.0 -a 0000:05:01.1 -- -p 0x3 --num-procs=2 --proc-id=1 + +2. send some packets,the number of packets is a random value between 20 and 256, packet type including IPV6/4,TCP/UDP, + refer to Random_Packet + +3. stop all process and check output:: + + the number of received packets for each process should bigger than 0. + summarize all received packets for all process should bigger than or equal to the number of sent packets + + +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.
