Specifying CPU cores for floating licenses can be useful in cases such as high-tech computing and application virtualization. This license model enables you to base licensing on the customer's computing resource requirements, increasing the pricing depth for your software offerings. For example, since a 4-CPU machine is double the speed of a 2-CPU machine, licensing the 4-CPU machine would be double the cost of licensing the 2-CPU machine.

To base floating licenses on CPU cores (example made in Windows environment):

1. Start a new project in your IDE. Base your code on the example in LM-X root directory\examples\network\network.c.
   
   
2. Include the LM-X library into your application (see the LM-X Quick Start Guide for more information).
   
   
3. Generate a floating license file using xmllicgengui (for Windows only; use xmlilicgen for other platforms), located in LM-X root directory\platform-specific directory, for example, C:\LM-X\Win32_x86. The settings for the floating license are shown in the following screenshot:
   
   
   
   An example XML template for a floating license looks like the following:
   
   ‹?xml version="1.0" encoding="utf-8"?›
   ‹LICENSEFILE›
   ‹SETTING END="2010-01-01" /›
   ‹FEATURE NAME="F1" /›
   ‹SETTING MAJOR_VERSION="1" /›
   ‹SETTING MINOR_VERSION="0" /›
   ‹SETTING COUNT="5" /›
   ‹SERVER_HOSTID›
   ‹SETTING ETHERNET="C8A516AD01AFC9FA" /›
   ‹/SERVER_HOSTID›
   ‹/FEATURE›
   ‹/LICENSEFILE›
   
   
4. To take the number of cores into account in your code (based on network.c example), change the checkout parameter:
   
   LMX_Checkout(LmxHandle, LMX_GetFeatureChecksum("F1"), 1, 0, 1)
   
   For processor-based licensing that sets the count to the number of logical CPUs, change the checkout parameter to:
   
   LMX_Checkout(LmxHandle, LMX_GetFeatureChecksum("F1"), 1, 0, LMX_LOGICAL_CPU_COUNT)
   
   For processor-based licensing that sets the count to the number of physical CPUs, change the checkout parameter to:
   
   LMX_Checkout(LmxHandle, LMX_GetFeatureChecksum("F1"), 1, 0, LMX_PHYSICAL_CPU_COUNT)
   
   
5. Compile your application. To check how it works, remember to start the license server (refer to the LM-X Quick Start Guide for more information).
