HPC-X Licensing Cost

Hi,

I am new to using mellanox switches.

i want to use mellanox infiniband switches for my rocks cluster.

I want to know about the HPC-X softwares. do we need to purchase its license or it's free.

there are some packages are in HPC-X like FCA, HPC-X Toolkit, MXM, HPC-X MPI, HPC-X OPENSHMEM, HPC-X UPC

if we purchased HPC-X all of the packages are comes by default or do we need to purchase it separately.

Also if we need job scheduler for my cluster are it is in HPC-X if yes which one I can use.

Please let me know.
