ArrayFire v3.6 Release

Umar Announcements, ArrayFire 3 Comments

Today we are pleased to announce the release of ArrayFire v3.6.  It can be downloaded from these locations: Official installers GitHub repository This latest version of ArrayFire is better than ever! We added several new features that improve the performance and usability of the ArrayFire library. The main features are: Support for batched matrix multiply Added the topk function Added the anisotropic diffusion filter We have also spent a significant amount of effort improving the internals of the library. The build system is significantly improved and organized. Batched Matrix Multiplication The new batch matmul allows you to perform several matrix multiplication operations in one call of matmul. You might want to call this function if you are performing multiple smaller matrix multiplication operations. Here ...

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 ...

ArrayFire v3.5 Official Release

Umar Announcements, ArrayFire, CUDA, Open Source, OpenCL 1 Comment

Today we are pleased to announce the release of ArrayFire v3.5, our open source library of parallel computing functions supporting CUDA, OpenCL, and CPU devices. This new version of ArrayFire improves features and performance for applications in machine learning, computer vision, signal processing, statistics, finance, and more. This release focuses on thread-safety, support for simple sparse-dense arithmetic operations, canny edge detector function, and a genetic algorithm example. A complete list of ArrayFire v3.5 updates and new features are found in the product Release Notes. Thread Safety ArrayFire now supports threading programming models. This is not intended to improve the performance since most of the parallelism is happening on the device, but it does allow you to use multiple devices in ...

Graphics Updates in ArrayFire v3.4

Pradeep Announcements, ArrayFire, OpenGL Leave a Comment

This post outlines the new graphics features available in ArrayFire v3.4:  Vector Fields, Overlays We have added visualization support to render ArrayFire array objects as vector fields. An example of how to visualize vector fields is included in ArrayFire v3.4. A screenshot of this example's output in multi-view mode is shown below, showcasing both static and dynamic vector field rendering. Previously, each graph (such as plot, hist, scatter, etc) was rendered in its own window (or view). Overlaying graphs was not supported. ArrayFire v3.4 now support graph overlays. Each draw call in ArrayFire is either rendered to a whole window (single view) or to a view, which is a portion of the screen obtained in multiview mode. The following image is an example of a ...

Performance Improvements to JIT in ArrayFire v3.4

Pavan Announcements, ArrayFire, Benchmarks Leave a Comment

ArrayFire uses Just In Time compilation to combine many light weight functions into a single kernel launch. This along with our easy-to-use API allows users to not only quickly prototype their algorithms, but also get the best out of the underlying hardware. This feature has been a favorite among our users in the domains of finance and scientific simulation. That said, ArrayFire v3.3 and earlier had a few limitations. Namely: Multiple outputs with inter-dependent variables were generating multiple kernels. The number of operations per kernel was fairly limited by default. In the latest release of ArrayFire, we addressed these issues to get some pretty impressive numbers. In the rest of the post, we demonstrate the performance improvements using our BlackScholes ...

ArrayFire release cycle

Pavan Announcements, ArrayFire Leave a Comment

Coming off of our latest release cycle, we think it is a good time to talk about our release policy more openly. In this post we are going to talk about our versioning scheme and the expected release cycle. The versioning scheme of the library will follow the Apache Portable Runtime guidelines. Each release version number will be of the following format arrayfire-x.y.z. The releases are going to be categorized broadly into the following categories based on the frequency and scope. Bug fix releases A bugfix release will bump the 3rd digit of the release version. These releases will neither add new functions nor break API and ABI compatiblity from the previous Feature release. Bug fix releases will be infrequent, ...
