v1.0.6

⚠️ Breaking Changes

• [4199d8f] Removed occa::cuda::getMappedPtr and occa::opencl::getMappedPtr and replaced them with

  occa::memory::ptr("mapped: true")
  

• [4199d8f] Allocating mapped/pinned memory (CUDA, OpenCL)

  It was too verbose and not as flexible to pass

  cuda: { mapped: true }
  opencl: { mapped: true }
  

  It's now the same for both CUDA and OpenCL

  mapped: true
  

• [4199d8f] Allocating unified memory (CUDA)

  The driver API uses the method cuMemAllocManaged so the prop was named accordingly

  cuda: { managed: true }
  

  However, most users know this feature as unified memory so we're switching the prop name to unified.
  Similar to mapped allocation, it has been shortened to

  unified: true

⭐️ Features

• [4199d8f] Added occa::memory::ptr(occa::properties)

• [abc3bea] Added #pragma occa attributes option

  #pragma occa attributes @kernel
  void addVectors(const int entries,
                  const float *a,
                  const float *b,
                  float *ab) {
  #pragma occa attributes @tile(16, @outer, @inner)
    for (int i = 0; i < entries; ++i) {
      ab[i] = a[i] + b[i];
    }
  }

  @kernel void addVectors(const int entries,
                          const float *a,
                          const float *b,
                          float *ab) {
    for (int i = 0; i < entries; ++i; @tile(16, @outer, @inner)) {
      ab[i] = a[i] + b[i];
    }
  }
