One of the challenges with a floating license is determining just how many seats you need. With Intel® Software Development Products, knowing what constitutes checking out a license can help answer this question. Every unique user of a product will check out a license seat during usage of that product. The exact action that causes a check-out varies by product.
A common question is how multiple users and multiple machines count license seats. A single user on a single machine will use one seat, even with multiple instances of a product in use (for instance, compiling in parallel). If you have multiple users, each user will check-out their own license seat. If a single user is using multiple machines (virtual or physical), each machine will check-out a separate license seat.
For example, if you have 10 users using the product simultaneously from a single shared server, you will need a minimum of 10 license seats. If one user launches 10 parallel compiles on a single machine, this will only consume one license seat. However, if those 10 compiles are run on 5 different machines (2 per machine), then 5 license seats will be used.
The key point is the unique combination of user and machine. A single user on a single machine will only need one seat. If the user or the machine is different, then each needs to check out a separate license seat. However, remember that floating license seats are checked out, not permanently assigned, so it is a question of how many user-machine combinations are accessing the products concurrently, not in total.
Also keep in mind that runtime components (runtime libraries, analysis tool collections) do not consume a license seat. So the number of users running a particular code or collecting analysis data is irrelevant to the number of seats you need.
Additionally, if you have a license for a product suite, using any component of that suite will check out a license seat for the entire suite, as the components are bundled together in the license. For example, if you have a user viewing Intel® VTune™ Amplifier results, and you have a license for Intel® Parallel Studio XE Professional Edition, that user will consume a seat for the entire suite, leaving one less seat for other users to compile.
