Mojo function

store_release

store_release[type: DType, //, scope: Scope = Scope(6), memory: Bool = True](ptr: UnsafePointer[SIMD[type, 1], address_space=address_space, alignment=alignment, mut=mut, origin=origin], value: SIMD[type, 1])

Performs an atomic store with release memory ordering semantics.

This function provides a memory barrier that ensures all previous memory operations from the calling thread are visible to other threads before this store is performed.

Note: - Only supported on NVIDIA GPUs. - Maps directly to PTX st.release instruction. - Ensures all previous memory operations complete before this store. - Critical for implementing synchronization primitives.

Parameters:

  • ​type (DType): The data type to store.
  • ​scope (Scope): Memory scope for the operation (default: Scope.SYSTEM).
  • ​memory (Bool): Whether to include memory side effects in constraints (default: True).

Args:

  • ​ptr (UnsafePointer[SIMD[type, 1], address_space=address_space, alignment=alignment, mut=mut, origin=origin]): Pointer to the memory location to store to.
  • ​value (SIMD[type, 1]): Value to store.
