This is the development repository of Triton, a language and compiler for writing highly efficient custom Deep-Learning primitives. The aim of Triton is to provide an open-source environment to write fast code at higher productivity than CUDA, but also with higher flexibility than other existing DSLs.
# This is a GPU kernel in Triton.
# Different instances of this

def add(X, Y, Z, N):
# In Triton, each kernel instance
# executes block operations on a
# single thread: there is no construct
# analogous to threadIdx
pid = program_id(0)
# block of indices
idx = pid * BLOCK + arange(BLOCK)
mask = idx < N
# Triton uses pointer arithmetics
# rather than indexing operators
x = load(X + idx, mask=mask)
y = load(Y + idx, mask=mask)
