triton.language.gt

triton.language.gt(x, y)

Element-wise greater-than comparison, the > operator on tensors.

• float — ordered greater-than (fcmp OGT)

• signed int — signed greater-than (icmp SGT)

• unsigned int — unsigned greater-than (icmp UGT)

The result is an int1 (boolean) tensor with the same shape.

参数:

• x (Block) -- the left operand

• y (Block) -- the right operand
