One embodiment can provide a method and system for tuning parameters of a numerical model of a physical system. During operation, the system can obtain, using a machine-learning technique, a parameter-transform model for mapping parameters of the numerical model at a first resolution to parameters of the numerical model at a second resolution, the second resolution being higher than the first resolution. The system can perform a parameter-tuning operation on the numerical model at a first resolution to obtain a first set of tuned parameters and apply the parameter-transform model on the first set of tuned parameters to obtain a second set of tuned parameters at a second resolution. The system can then generate behavior information associated with the physical system by running the numerical model at the second resolution using the second set of tuned parameters.

System and method for model parameter optimization

A method and system for software emulation of hardware support for multi-threaded processing using virtual hardware threads is provided. A software threading system executes on a node that has one or more processors, each with one or more hardware threads. The node has access to local memory and access to remote memory. The software threading system manages the execution of tasks of a user program. The software threading system switches between the virtual hardware threads representing the tasks as the tasks issue remote memory access requests while in user privilege mode. Thus, the software threading system emulates more hardware threads than the underlying hardware supports and switches the virtual hardware threads without the overhead of a context switch to the operating system or change in privilege mode.
