Question about the dimension of head

[alihassanijr]

Hello,
Thank tou for your interest.

We fixed the dimension for our purposes to get a minor speed improvement. You can modify the line #define DIM 32 and change it to 64 and recompile if you're interested in doing that.
We plan to release either a separate version of the kernel with dynamic dims, or merge that into the kernel directly.

Hi, I want to double check that no matter the value of dim and num_heads, the dim of head is always 32?

[alihassanijr]

Hi,
No, we specifically kept the per-head dim at 32 for our 4 variants, and extended heads for larger variants. That's why we kept it fixed in the kernel.

Just an update,
You can now use arbitrary dims per head with v0.11 (PR #23 )

@PeiqinZhuang If that resolves your question, feel free to close the issue.

Hi, I have one question. Should I change the block size from 32 to 64, if I change the default dimension from 32 to 64.

Sorry, to what exactly are you referring by block size?
