Wouldn't the Nsight Systems suite provide coverage here? Are the tricky cases difficult to debug with the standard CUDA tooling stack?

Does anyone know how their KV cache sync mechanism compares to newer P2P communication layers like nixl, uccl p2p, etc.? The authors mention that NCCL and Ray initialization were too slow (see quote below), but from the description it sound

What kind of NCCL testing are you thinking about? Always curious what’s hardest to validate in people’s setups.

For Linux kernel dev, I found Linux Kernel Programming: A Comprehensive Guide to Kernel Internals to be a really helpful resource. For eBPF, the early chapters of Brendan Gregg’s BPF Performance Tools gave me the context I needed to get sta

For kernel dev and eBPF, what kinds of resources or tutorials have you tried in the past? Have you ever tried building something small or contributing to an existing project? Curious to hear what hurdles you ran into.

Even if you have experience with DWARF, I think you will learn something new from the book. I work on CNCF Pixie, which uses DWARF for eBPF uprobes and dynamic instrumentation. While I understood how our project uses DWARF, the book made ma

It covers version 4, but it explains differences with v5 as they come up.

Also second that the book is a fantastic read. I work in the eBPF profiling space (on CNCF Pixie) and this has helped me understand DWARF concepts that I previously took at face value in our project's implementation.

The approach you describe above is common for similar projects: - Pixie ( https://px.dev ) -- which I contribute to - Beyla ( https://github.com/grafana/beyla ) - Coroot ( https://github.com/coro

Definitely agree. As I've looked into instrumentation/tracing, it has helped me more fearlessly look at the kernel. Ftrace is another tool that's helped me level up as well ( https://blog.px.dev/ebpf-probes-and

Yep, that's correct. It uses eBPF upprobes to attach to the SSL_write/SSL_read functions.
