User guide

katsdpsigproc is a Python package aimed at signal processing in radio astronomy, with a focus on GPU acceleration. It consists of several pieces:

• A framework for writing accelerated code using CUDA or OpenCL;

• A lower-level abstraction layer to paper over some differences between CUDA and OpenCL, which is used by the higher-level layer above;

• Implementations of a number of algorithms (some specific to radio astronomy), both on the CPU and on accelerators.

• Introduction
• Initialization
• Buffers
• Kernels
• Operations
• Built-in operations
• Autotuning
• Synchronization
• Testing
• Asynchronous resource management
• Macros for kernels
• Thread safety
• Undocumented topics
