ArrayFire v3.5.1 Release

miguel@arrayfire.com Announcements, ArrayFire 1 Comment

We are excited to announce ArrayFire v3.5.1! This release focuses on fixing bugs and improving performance. Here are the improvements we think are most important:

Performance improvements

  • We've improved element-wise operation performance for the CPU backend.
  • The af::regions() function has been modified to leverage texture memory, improving its performance.
  • Our JIT engine has been further optimized to boost performance.

Bug fixes

  • We've squashed a long standing bug in the CUDA backend responsible for breaking whenever the second, third, or fourth dimensions were large enough to exceed limits imposed by the CUDA runtime.
  • The previous implementation of af::mean() suffered from overflows when the summation of the values lied outside the range of the backing data type. New kernels for each of our backends have been written to prevent this issue.
  • The af::canny() function has been patched with a workaround to avoid a bug in Apple's OpenCL driver. We are working on releasing an upcoming patch to fix all examples that are similarly affected.
