Advances and challenges in computational plasma science

Various advances and challenges in computational science such as microturbulence and magnetohydrodynamics are discussed. THe advances are mainly enabled by two key areas such as innovative advances in analytic and computational methods and access to powerful new computational resources. Excellent progress has been made in developing codes for which computer run-time and problem-size scale well with the number of processors on massively parallel processors (MPP). The advances in both particle and fluid simulations of fine-scale turbulence and large-scale dynamiccs have produced increasingly good agreement between experimental observations and computational modeling.
