neutron scattering and HPC

F. Bao, math depart

HPC, neutro scattering

I(Q,omega), Q is the 3D neutron wave vector transfer
omega is the energy transfer between neutron and material sample.

I = S*R (convolution).

S is modeled scattering function, interest from material science.

Partition all parameters into several subvectors.

Model: silicon crystal structure with first to fourth nearest neighbor interactions

hierarchical parameter space

latin hypertube sampling
