Just-In-Time Compilation¶
JIT compilation in the nbackend is managed by subclasses of JitBase.
A JIT compiler may freely be created and configured by the user.
It can then be passed to create_kernel using the jit argument of
CreateKernelConfig, in which case it is hooked into the KernelFunction.compile method
of the generated kernel function:
my_jit = MyJit()
kernel = create_kernel(ast, CreateKernelConfig(jit=my_jit))
func = kernel.compile()
Otherwise, a JIT compiler may also be created free-standing, with the same effect:
my_jit = MyJit()
kernel = create_kernel(ast)
func = my_jit.compile(kernel)
Currently, only wrappers around the legacy JIT compilers are available.
Legacy Just-In-Time Compilation¶
Historically, pystencils provides two main pathways for just-in-time compilation:
The cpu.cpujit module for CPU kernels, and the gpu.gpujit module for device kernels.
Both are available here through LegacyCpuJit and LegacyGpuJit.
- class pystencils.backend.jit.JitBase¶
Base class for just-in-time compilation interfaces implemented in pystencils.
- abstract compile(kernel)¶
Compile a kernel function and return a callable object which invokes the kernel.
- Return type:
- Parameters:
kernel (KernelFunction) –
- class pystencils.backend.jit.LegacyCpuJit¶
Wrapper around
pystencils.cpu.cpujit- compile(kernel)¶
Compile a kernel function and return a callable object which invokes the kernel.
- Return type:
- Parameters:
kernel (KernelFunction) –
- class pystencils.backend.jit.NoJit¶
Not a JIT compiler: Used to explicitly disable JIT compilation on an AST.
- compile(kernel)¶
Compile a kernel function and return a callable object which invokes the kernel.
- Return type:
- Parameters:
kernel (KernelFunction) –
- pystencils.backend.jit.no_jit = <pystencils.backend.jit.jit.NoJit object>¶
Disables just-in-time compilation for a kernel.
