gnuradio/volk: Release v2.2.0
No full textHi everyone,
we have a new VOLK release v2.2.0!
We want to thank all contributors. This release wouldn't have been possible without them.
We're curious about VOLK users. Especially we'd like to learn about VOLK users who use VOLK outside GNU Radio.
If you have ideas for VOLK enhancements, let us know. Start with an issue to discuss your idea. We'll be happy to see new features get merged into VOLK.
The v2.1.0 release was rather large because we had a lot of backlog. We aim for more incremental releases in order to get new features out there.
Highlights
VOLK v2.2.0 updates our build tools and adds support functionality to make it easier to use VOLK in your projects.
Dropped Python 2 build support
Removed Python six module dependency
Use C11 aligned_alloc whenever possible
MacOS posix_memalign fall-back
MSVC _aligned_malloc fall-back
Add VOLK version in volk_version.h (included in volk.h)
Improved CMake code
Improved code with lots of refactoring and performance tweaks

gnuradio/volk: Release v2.3.0
No full text[2.3.0] - 2020-05-09
Hi everyone!
VOLK 2.3 is out! We want to thank all contributors. This release wouldn't have been possible without them. We saw lots of great improvements.
On GNU Radio 'master' VOLK was finally removed as a submodule.
Currently we see ongoing discussions on how to improve CPU feature detection because VOLK is not as reliable as we'd like it to be in that department. We'd like to benefit from other open source projects and don't want to reinvent the wheel. Thus, one approach would be to include cpu_features as a submodule.
Highlights
Better reproducible builds
CMake improvements
ORC is removed from the public interface where it was never supposed to be.
CMake fixes for better usability
Updated and new CI chain
TravisCI moved to new distro and does more tests for newer GCC/Clang
Github Actions
Add Action to check proper code formatting.
Add CI that also runs on MacOS with XCode.
Enforce C/C++ coding style via clang-format
Kernel fixes
Add puppet for power_spectral_density kernel
Treat the mod_range puppet as a puppet for correct use with volk_profile
Fix index_max kernels
Fix rotator. We hope that we finally found the root cause of the issue.
Kernel optimizations
Updated log10 calcs to use faster log2 approach
Optimize complexmultiplyconjugate
New kernels
accurate exp kernel is finally merged after years
Add 32f_s32f_add_32f kernel to perform vector + scalar float operation

Vector-Optimized Library of Kernels (VOLK)
No full textVOLK is the Vector-Optimized Library of Kernels. It is a free library that contains kernels of hand-written SIMD code for different mathematical operations. Since each SIMD architecture can be very different and no compiler has yet come along to handle vectorization properly or highly efficiently, VOLK approaches the problem differently. For each architecture or platform that a developer wishes to vectorize for, a new proto-kernel is added to VOLK. At runtime, VOLK will select the correct proto-kernel. In this way, the users of VOLK call a kernel for performing the operation that is platform/architecture agnostic. This allows us to write portable SIMD code that is optimized for a variety of platforms

<p>This is the VOLK v3.1.2 release! We want to thank all contributors.
This release wouldn't have been possible without them.</p>
<p>The last maintenance release revealed issues in areas that are difficult to test.
While the changes to the library should be minimal, usability should be improved.
Most notably, we build and deploy <a href="https://www.libvolk.org/docs">the VOLK documentation</a>
automatically now.</p>
