High-performance simulations of continuously variable transmission dynamics
نویسندگان
چکیده
The paper describes a parallel computational model simulating continuously variable transmission (CVT) dynamics. A specific feature of the CVT model is the combination of relatively small problem sizes (about 1000 unknowns) and high computational costs (up to several weeks of sequential code computations for a thirty seconds simulation period). The main source of computational complexity here is the calculation of non-linear contact forces acting between transmission parts at each step of the explicit time integration procedure. Below we analyze simulation workflow and runtime load distribution among the application modules. Based on the profiling data, we present a task parallel multithreaded implementation of the model over shared memory and discuss steps towards further parallelization.
