  The two-dimensional supersymmetric Yang-Mills (SYM) theory with sixteen
supercharges at large $N$ and strong 't~Hooft coupling is conjectured to be
dual to certain supergravity solutions in the decoupling limit. We discretize
the gauge theory preserving a subset of supersymmetries on the lattice. Based
on the choice of a point in the moduli space for the expansion of the gauge
links to target the correct continuum theory, one ends up with different
lattice geometries. In our previous work, we explored the free energy and the
phase structure on a skewed torus corresponding to $A_{2}^{*}$ lattice
geometry. Here, we will consider square lattice and calculate the free energy,
equation of state and speed of sound in this strongly coupled supersymmetric
plasma. Since there is no shear viscosity in two dimensions, we comment on the
expectations for the bulk viscosity from the calculations on the dual
supergravity side, which unlike the conformal $\mathcal{N}=4$ SYM case does not
vanish and is proportional to the trace of energy-momentum tensor.
