This is the initial public release of GPU Reshape, a powerful tool that leverages on-the-fly instrumentation of GPU operations with instruction level validation of potentially undefined behavior.

Standalone desktop application, no integration required.

This release includes the following features:

• Resource Bounds
  Validation of resource read / write coordinates against its bounds.
• Export Stability
  Numeric stability validation of floating point exports (UAV writes, render targets, vertex exports), e.g. NaN / Inf.
• Descriptor Validation
  Validation of descriptors, potentially dynamically indexed. This includes undefined, mismatched (compile-time to runtime), out of bounds descriptor indexing, and missing table bindings.
• Concurrency Validation
  Validation of resource concurrency, i.e. single-producer or multiple-consumer, between queues and events.
• Resource Initialization
  Validation of resource initialization, ensures any read was preceded by a write.
• Infinite Loops
  Detection of infinite loops. Experimental.

Additionally, certain features, such as descriptor validation and loops, can safeguard a potentially erroneous operation, preventing undefined behaviour during instrumentation. This is especially useful if the error would result in a GPU crash, limiting the application’s ability to write out useful debug information of the issue.
