triton-ascend-example-double-kernel

triton-ascend-example-double-kernel is a skill for Claude Code, Codex from mindspore-ai/akg. It costs 66 tokens per session (375 once invoked), scanned A, original, Apache-2.0.

A Triton Ascend example that runs two kernels in sequence, storing the first calculation in a temporary buffer before the second reads it.

In plain words
What is it for?
Use it when building staged Triton computations that need two dependent processing steps on Ascend hardware.
Why use it?
It provides a pattern for operations that cannot or should not be completed in one kernel, such as transforming data before reducing it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

triton-ascend-example-double-kernel scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Double Kernel(双内核调用)— Triton Ascend 示例

当一个算子需要分两步计算(如先做变换再做归约),可在 forward 中依次启动两个 kernel:

class ModelNew(torch.nn.Module):
    def __init__(self):
        super().__init__()
        try:
            self.VEC_CORE_NUM = torch_npu.npu.npu_config.get_device_limit(0).get("vector_core_num", 40)
        except:
            self.VEC_CORE_NUM = 40

    def forward(self, x):
        intermediate = torch.empty_like(x)
        output = torch.empty(out_shape, dtype=x.dtype, device=x.device)
        grid = (self.VEC_CORE_NUM,)

        kernel_stage1[grid](x, intermediate, ..., CORE_NUM=self.VEC_CORE_NUM)
        kernel_stage2[grid](intermediate, output, ..., CORE_NUM=self.VEC_CORE_NUM)

        return output

要点

  • 中间缓冲区用 torch.empty_like 或指定 shape 分配
  • 确保 stage1 写完后 stage2 再读(Triton Ascend 默认隐式同步)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
