Hi Kedi,

HPC licensing packs allow multiple cores to be used during an analysis.

By default, Ansys applications allow 4 CPU cores to be used without HPC licensing.
HPC Packs provide a method to expand beyond those 4 cores.
A single HPC Pack would allow 5-12 CPU cores, two HPC Packs 13-36 CPU cores, three HPC Packs 37-132 CPU cores.

Solving parametrics or GPU 

1. Regarding GPU's:

HPC licensing enables the use of cores and GPUs to accelerate simulations. In general, each core requires one unit of HPC, while each GPU requires eight units. The selected HPC license type determines which license is used, and how units of HPC are converted to license counts. For details, see the discussion of licensing under Options in Setting HPC and Analysis Options.
 
If the number of simulation jobs exceeds the number of GPUs in a system, the excessive jobs will fall back to CPUs and will be accelerated by up to 8 CPU cores for each job.
