  An in-house large eddy simulation tool is developed in order to reproduce
high fidelity results of compressible jet flows. The large eddy simulation
formulation is written using the finite difference approach, with an explicit
time integration and using a second order spatial discretization. The energy
equation is carefully discretized in order to model the energy equation of the
filtered Navier-Stokes formulation. Such nu\-me\-ri\-cal studies are very
expensive and demand high performance computing. Message passage interface
protocols are implemented into the code in order to perform parallel
computations. The present work addresses the computational performance of the
solver running on up to 400 processors in parallel. Different mesh
configurations, whose size varies from approximately 5.9 million points to
approximately 1.0 billion points, are evaluate in the current paper. Speedup
and efficiency curves are evaluated in order to assess the strong scalability
of the solver.
