Bloqade supports CUDA acceleration. To use CUDA acceleration, you will need a NVIDIA graphics processing unit (GPU).
To use CUDA accelerators, you need to install the CUDA package and the Adapt package:
pkg> add CUDA Adapt
This will automatically download all the needed dependencies of the CUDA toolkit. This functionality requires CUDA toolkit 11.6+ and CUSPARSE 11.4+. You can check your version via
Converting your CPU-based simulation to CUDA-based simulation is extremely simple: just use the
cu function from
CUDA on the register object, which will convert the CPU-based register to a CUDA-based register, e.g.:
using CUDA, Adapt reg = zero_state(5) dreg = adapt(CuArray, reg) # device register
For emulation, you can call
cu on your emulation object to convert everything (emulation intermediate memory, etc.) into the GPU memory, e.g.:
adapt(CuArray, KrylovEvolution(reg, clocks, h))
Other codes in Bloqade should work with CUDA automatically.
