wat acctually is a alpha software. how can it be utilized
"Alpha" software is software that is still under development. It may be incomplete and not tested sufficiently for productive usage.
On the "whatif" web site (whatif.intel.com), Intel provides such software free of charge, but without any warranty that it works as expected or will be supported in future. Nevertheless,this gives you the opportunityto experiment with new capabilities long before they become available as a commercial product.
