GPGPU for orbital function evaluation with a new updating scheme
GPGPU orbital function evaluation new updating scheme Computational Physics
2012/4/19
We accelerated an {\it ab-initio} QMC electronic structure calculation by using GPGPU. The bottleneck of the calculation for extended solid systems is replaced by CUDA-GPGPU subroutine kernels which b...
