DESCRIPTION:We will discuss methods of computing instanton partition funct
 ions for arbitrary gauge groups including the exceptional ones. Even thoug
 h there is no explicit algebraic construction of instanton moduli space av
 ailable for the exceptional groups\, we're able to evaluate the partition 
 function using the blow-up recursion relations derived by Nakajima and Yos
 hioka. We compare this result with the proposal based on the superconforma
 l index of SCFTs with E6\, E7 global symmetry. We also compare our result 
 with the norm of certain coherent states of W-algebras and thereby extendi
 ng the AGT correspondence for pure YM theory to all gauge groups.
