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 t…

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 B…

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? Curio…

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. Whi…

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 va…

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://…

Disclaimer: I'm a maintainer of the project Pixie [1] is a similar project and offers the self hosted model you are looking for. We also support 11 application protocols [2] with T…

Disclaimer: I'm a maintainer of the project Pixie ( https://px.dev ) can be installed in under 5 mins and gives this level of visibility across all applications. No need to change …

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…

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

Author here :). Happy to answer any questions on this TLS tracing stuff.
