We review the quiver matrix model (the ITEP model) in the light of the recent<br />
progress on 2d-4d connection of conformal field theories, in particular, on the<br />
relation between Toda field theories and a class of quiver superconformal gauge<br />
theories. On the basis of the CFT representation of the beta deformation of the<br />
model, a quantum spectral curve is introduced as &lt;&lt; det (x- i g_s \partial<br />
\phi(z)) &gt;&gt;=0 at finite N and for beta \neq 1. The planar loop equation in the<br />
large N limit follows with the aid of W_n constraints. Residue analysis is<br />
provided both for the curve of the matrix model with the &quot;multi-log&quot; potential<br />
and for the Seiberg-Witten curve in the case of SU(n) with 2n flavors, leading<br />
to the matching of the mass parameters. The isomorphism of the two curves is<br />
made manifest.
