@swolchok you mentioned rsqrt was used since Llama2. I'm wondering how it would help the overall performance. Probably it's fine because it's not a performance bottleneck there. It's used in RMSNorm, where the sqrt is applied to a scalar of RMS(x), not on each element of x.

improve this test by adding dynamic_shape support

it's a pointwise operator, why does it care about the shape? Everything is the same as sqrt including the test

Yeah, just checking boxes, i.e. adding dynamic shape test for every operator.

@swolchok you mentioned rsqrt was used since Llama2. I'm wondering how it would help the overall performance. Probably it's fine because it's not a performance bottleneck there. It's used in RMSNorm, where the sqrt is applied to a scalar of RMS(x), not on each element of x.

it's a pointwise operator, why does it care about the shape? Everything is the same as sqrt including the test

Yeah, just checking boxes, i.e. adding dynamic shape test for every operator.

LGTM. Thanks @swolchok for this quick fix! @mcr229 and @digantdesai could you take a look?

@swolchok you mentioned rsqrt was used since Llama2. I'm wondering how it would help the overall performance. Probably it's fine because it's not a performance bottleneck there. It's used in RMSNorm, where the sqrt is applied to a scalar of RMS(x), not on each element of x.

Nit: Do you want to improve this test by adding dynamic_shape support like this?

improve this test by adding dynamic_shape support
it's a pointwise operator, why does it care about the shape? Everything is the same as sqrt including the test

Yeah, just checking boxes, i.e. adding dynamic shape test for every operator.
