GpuBlockIndex¶
The index of the running block within the grid.
Declaration¶
Syntax¶
GpuBlockIndex(int dim, ttype type, expr? value)
Arguments¶
Argument |
Description |
|---|---|
|
which dimension to report, counting from zero. |
|
the type of the expression. |
|
the compile time value of the expression, when the frontend could fold it; |
Return values¶
The value of the expression.
Description¶
The block index counts from zero, up to the grid_size the kernel was
launched with.
