Polar Signals

Dash0 welcomes Polar Signals to the team. They built the leading continuous profiler for cloud native workloads, with GPU and CUDA support, and created Parca, the open source profiling project behind it. Profiling will live natively in Dash0, next to traces, metrics and logs. eu1.hubs.ly/H0xG-d70

🚀 Incredibly excited to share: Polar Signals is joining Dash0! 🧊 www.polarsignals.com/blog/posts/2...

🔥Flame charts are now GA for all CPU profiles on Polar Signals Cloud. X-axis = wall-clock time, so periodic GC, phase shifts, and lock contention show up as patterns instead of getting averaged out. www.polarsignals.com/blog/posts/2...

The Polar Signals profiler got a major upgrade. New dashboard, and everything is faster and smoother 🚀 We can’t wait for you to try it out! Here's what's new and how we did it: www.polarsignals.com/blog/posts/2...

What if loading a data lake was as simple as writing a SQL query? In our latest engineering deep dive, we explain how we explored loading Great Lakes tables using DataFusion SQL queries in an effort to increase performance. 🚀 🧊 Read the full post: www.polarsignals.com/blog/posts/2...

Less context, better answers. 🔥 The new @polarsignals.com MCP makes smaller, more effective tool calls and iterates on what's actually worth querying. www.polarsignals.com/blog/posts/2...

Two of our favorite things on the blog today: 1) Experimenting with cutting-edge GPU-accelerated columnar storage. 🚀 2) Dogfooding our GPU Profiler. 📊 Let us know what you think! www.polarsignals.com/blog/posts/2...

Ever wondered how a profiler knows which JavaScript function is hot when V8 compiles your code three different ways? Brennan went deep on unwinding and symbolizing V8 stacks across Sparkplug, Maglev, and TurboFan. The detective work behind every flame graph. 🔥 www.polarsignals.com/blog/posts/2...

🚀 Launching today: GPU PC sampling in production. Instruction-level profiling telling you why and where warps stall. Whether it is memory latency, scoreboard waits, or barriers. 🧊 Previously NSight-only territory. Now running in prod with low overhead. www.polarsignals.com/blog/posts/2...

New Blog Alert! Learn how we overcame eBPF limits to unwind deeply nested PyTorch training stacks and learned some cools things along the way: www.polarsignals.com/blog/posts/2...

Tired of Node.js flamecharts full of `a`, `m`, and `_0x3f2`? We just shipped source maps support for Node.js profiles in Polar Signals Cloud. Just add a plugin to your build pipeline, and your profiles show the real code. Know more: www.polarsignals.com/blog/posts/2...
