GPU PTX and SASS Mini Bundle

You’ve mastered the architecture—now it’s time to own the performance.

Every GPU developer hits the same wall: the profiler says you’re close to peak, but you know there’s still headroom. What’s missing isn’t another compiler flag—it’s visibility into the hardware’s final truth. That truth lives in SASS, the real machine code running on NVIDIA GPUs.

Mastering PTX and SASS – Volume II takes you past theory into the territory where nanoseconds matter. Here you’ll learn how to read, analyze, and tune instruction streams with surgical precision. You’ll uncover how schedulers pair ops, how register pressure throttles throughput, and how to turn your kernels into clock-cycle-balanced engines of pure efficiency.

This book is for engineers who refuse to settle for “good enough.” It turns profiling, disassembly, and optimization into a repeatable process—one grounded in data, not superstition. From tensor cores to warp shuffles, from atomic operations to multi-GPU scaling, you’ll learn how real experts bend hardware to their will.

Volume I built the foundation; Volume II shows you how to weaponize it.
If you’re ready to squeeze every drop of performance from your GPU—and understand exactly how you did it—this is the manual you’ve been waiting for.

If you’ve ever wondered why your GPU code hits a wall long before the hardware’s limits, this book tells you why—and how to break through it.

Most programmers stop where the compiler starts. They trust nvcc to make the right decisions, to manage registers, to schedule instructions, and to use memory efficiently. But the compiler doesn’t know your problem. It guesses. And in GPU computing, guessing costs performance.

Mastering PTX and SASS – Volume I pulls back the curtain on NVIDIA’s virtual machine—the PTX instruction set that every CUDA kernel becomes before it touches silicon. You’ll learn how threads, warps, and memory really behave at the hardware level, how each instruction interacts with caches and pipelines, and how to read, write, and reason about PTX like an architect, not just a coder.

This isn’t a surface-level “how-to.” It’s a deep, methodical tour through the machinery of modern GPUs—built for professionals who want measurable, repeatable speedups, not guesswork. You’ll discover how the compiler transforms your high-level logic into executable reality, and where you can step in to take control.

By the time you finish, you won’t be relying on compiler magic. You’ll understand it, improve it, and surpass it.

Mastering PTX and SASS – Volume I gives you the foundation; Volume II takes you to the bleeding edge of optimization. Together, they turn GPU performance from a mystery into a science.
