 Since these logical core numbers, and their mapping to specific cores on specific NUMA sockets, can vary from platform to platform,

+On initialization of the EAL layer by a DPDK application, the logical cores to be used and their socket location are displayed.
 This information can also be determined for all cores on the system by examining the ``/proc/cpuinfo`` file, for example, by running cat ``/proc/cpuinfo``.
 The physical id attribute listed for each processor indicates the CPU socket to which it belongs.
 This can be useful when using other processors to understand the mapping of the logical cores to the sockets.

+Additional sample applications are included in the DPDK examples directory.
 These sample applications may be built and run in a manner similar to that described in earlier sections in this manual.
 In addition, see the *DPDK Sample Applications User Guide* for a description of the application,
 specific instructions on compilation and execution and some explanation of the code.

-Additional Test Applications
-----------------------------
-
-In addition, there are two other applications that are built when the libraries are created.
-The source files for these are in the DPDK/app directory and are called test and testpmd.
-Once the libraries are created, they can be found in the build/app directory.
-
-*   The test application provides a variety of specific tests for the various functions in the DPDK.
-
-*   The testpmd application provides a number of different packet throughput tests and
-    examples of features such as how to use the Flow Director found in the Intel® 82599 10 Gigabit Ethernet Controller.
