Jonathan Worthington has requested an extension of $20,000 for his Perl 6 Performance and Reliability Engineering grant. This will allow him to dedicate another 333 hours to this work. His previous work was successfully delivered as reported in the latest reports: July August September October November December Jonathan writes: "I recently wrote about some of the things I plan to work on for Perl

Jonathan writes: December came with some travel and vacation, and so wasn't ideal for working on the larger ongoing tasks. I did, however, get in numerous smaller fixes, as well as reducing the overhad on regex matching and improving the performance of regex interpolation. Other fixes included a memory leak that was observed to impact Cro applications, a couple of GC errors, and a crash involving a certain interaction of

Jonathan writes: In November I continued my work towards partial escape analysis and related optimiztions in MoarVM. In terms of the analysis itself, I spent some time designing and starting to implement deoptimization handling. If we use the analysis to decide to eliminate an allocation, then this decision will have been made based on specialized code containing guards. In the event these guards fail, we must be able to undo

The 2019 DC-Baltimore Perl Workshop will be in Silver Spring, MD, on April 6th, 2019. The call for talks is now open and this year's themes are Perl and related technologies. Proposals can be submitted through the workshop website until Jan 31, 2019. Registration is also open and attendance is free for speakers, students, and people currently between jobs. We hope to see you there!

Brrt has hit the ground running on his MoarVM JIT Compiler grant. Here is his interim report: I wanted to start with floating point support, which has two subtasks: Ensure that DynASM encodes SSE instructions with variadic registers correctly. Ensure that the JIT itself accepts and works with floating point registers. I finished the first two of those tasks. For some context, x86-64 instruction encoding rules require an extra byte

This is a monthly report by Dave Mitchell on his grant under Perl 5 Core Maintenance Fund. We thank the TPF sponsors to make this grant possible. I've been almost entirely absent from perl stuff for the last couple of months due to doing other things and lack of enthusiasm. Hopefully things will start picking up. Did a little bit of work on a couple of tickets SUMMARY: 0:40

"Overview" tab is now functional but in flux. The "Routines" tab has been improved to include sorting functionality for columns, a minimal view in the "Paths" sub tab and a new "Callers" sub tab. An "Allocations" top level tab has also been added. Read more at: Full Screen Ahead! Full Screen Ahead! Whew, it's been a long time since the last report already! Let's see what's new. Photo by

Jonathan writes: My performance work in October focused for the most part on escape analysis and scalar replacement. This work remains in a branch, however it has now reached the milestone of performing its first couple of real-world optimizations, eliminating short-lived boxes and wrapper objects across inline boundaries. I also started with some long-planned work on more aggressive optimization of lexical variables, such that they are stored as "locals" where

Jonathan writes: My main deliverable in September was a significant improvement to the performance of object construction and initialization. I wrote a blog post describing the ways in which this was achieved. I also improved the performance of array assignment, took on a tricky bug that stood in the way of merging a GC performance improvement, and took another small step with the work on escape analysis. 5:33 Lots of
