Taschenbuch. Zustand: Neu. Neuware - Hardware-Agnostic Mojo: Writing Portable Kernels from CPU to GPUFor decades, software engineers and AI practitioners have been trapped by a brutal development compromise: write highly portable code that runs slowly everywhere, or write hyper-optimized parallel code that locks your infrastructure to a single hardware vendor. If you build performance-critical applications or deep learning pipelines using proprietary frameworks like CUDA, your software is restricted exclusively to a single ecosystem. Changing your cloud infrastructure means facing a multi-million-dollar rewriting penalty.Hardware-Agnostic Mojo shatters this monopoly. This comprehensive manual introduces the paradigm-shifting capabilities of the Mojo programming language and the Multi-Level Intermediate Representation (MLIR) compiler framework. This book provides a production-ready blueprint for designing mathematical algorithms, spatial convolution filters, and high-performance tensor workloads that decouple execution logic from physical silicon constraints.Moving systematically from core systems hardware architecture to low-level compilation mechanics, you will learn how to: - Harness Compile-Time Metaprogramming: Replace fragile C++ preprocessor macros with type-safe parameters to freeze loop boundaries and memory strides directly into compiled binaries.- Optimize Matrix and Vector Primitives: Transition traditional mental models into Mojo's safety-first syntax, using register tiling, stride tuning, first-class SIMD vectors, and lane masks to maximize single-core processing capabilities.- Architect Universal Thread Grids: Map multidimensional data topologies and coordinate indices smoothly across diverse processing systems whether routing to safe scalar CPU worker pools or fine-grained parallel GPU streaming multiprocessors.- Deploy Portably to Production: Package highly optimized kernels into unmanaged C-ABI shared libraries, implement dynamic runtime CPU dispatching safety layers, and insulate your codebase from vendor lock-in forever.Complete with complete, official Mojo standard library code examples, benchmarks, and technical unit exercises, this manual eliminates the abstract 'lowest common denominator penalty' of legacy wrappers. You will write hardware-agnostic code once, and let the compiler scale your architectural intent to the absolute performance ceiling of whatever chip it encounters next.Stop wasting valuable engineering cycles maintaining fractured, vendor-locked codebases. Click the button below to buy your copy of Hardware-Agnostic Mojo today, master the future of high-performance parallel computing, and build runtime-resilient code paths that conquer any silicon runway from CPU to GPU.…

Taschenbuch. Zustand: Neu. Neuware - When your application transitions from a cozy local development sandbox to handling thousands of concurrent real-time transactions under intense production pressure, traditional software architecture patterns fail. In the world of high-velocity backend engineering, a single unindexed database query, an unthrottled tracing loop, or an unmanaged process mailbox can instantly trigger cascading node failures, exhaust host memory, and knock your entire platform offline.Elixir OTP in Production: The Patterns, Anti-Patterns, and Performance Secrets is the definitive, production-hardened guide to engineering resilient, high-throughput systems on the BEAM virtual machine. Moving past basic syntax guides and textbook theories, this book exposes the hidden execution-context mechanics that separate fragile setups from self-healing, enterprise-grade clusters.Through highly detailed code laboratories, deep architectural deconstructions, and real-world system recovery case studies, you will learn how to: - Eliminate Memory Exhaustion: Master Ecto repository streams and database cursors to process multi-million-row datasets smoothly on constrained hardware without spiking your RAM footprint.- Diagnose Pool Starvation: Detect internal checkout queue backups using low-level telemetry metrics before they trip your system circuit breakers and cause cascading microservice deadlocks.- Isolate Fault Hierarchies: Implement non-blocking asynchronous startup boundaries, programmatic release tasks, and ironclad supervisor restart configurations to keep your node state safe from toxic data packets.- Secure Production Observability: Leverage the ultimate performance secret of rate-limited: recon_trace and safe multi-layered Phoenix.LiveDashboard setups to trace live memory values without impacting active traffic.- Scale Horizontally Natively: Build self-healing cluster meshes with libcluster and automate node fencing sentinels to completely eliminate the split-brain data pollution caused by cloud network netsplits.Stop rewriting your backend infrastructure every time your market traffic spikes. Stop flying blind during live platform degradations. Transform your code into a self-regulating digital immune system that thrives under load, isolates exceptions on the spot, and maintains flat operational signatures under peak enterprise volume.Don't wait for your next high-volume traffic surge to expose hidden vulnerabilities in your backend layout. Master the deep operational patterns of the BEAM virtual machine, bulletproof your architecture against global synchronous failures, and build systems that literally never crash.
