  We study vacuum structure of N=1 supersymmetric quiver gauge theories which
can be realized geometrically by D brane probes wrapping cycles of local
Calabi-Yau three-folds. In particular, we show that the A_2 quiver theory with
gauge group U(N_1) \times U(N_2) with N_1 / 2 < N_2 < 2N_1 / 3 has a regime
with an infrared free description that is partially magnetic and partially
electric. Using this dual description, we show that the model has a landscape
of inequivalent meta-stable vacua where supersymmetry is dynamically broken and
all the moduli are stabilized. Each vacuum has distinct unbroken gauge
symmetry. B-terms generated by the supersymmetry breaking give rise to gaugino
masses at one-loop, and we are left with the bosonic pure Yang-Mills theory in
the infrared. We also identify the supersymmetric vacua in this model using
their infrared free descriptions and show that the decay rates of the
supersymmetry breaking vacua into the supersymmetric vacua can be made
parametrically small.
