Benchmarking and scaling studies of a pseudospectral code Tarang for   turbulence simulations
  Tarang is a general-purpose pseudospectral parallel code for simulating flows involving fluids, magnetohydrodynamics, and Rayleigh-B\'{e}nard convection in turbulence and instability regimes. In this paper we present code validation and benchmarking results of Tarang. We performed our simulations on $1024^3$, $2048^3$, and $4096^3$ grids using the {\em HPC system} of IIT Kanpur and {\em Shaheen} of KAUST. We observe good "weak" and "strong" scaling for Tarang on these systems.
