My grant work in August focused on improving the performance of a number of very commonly used constructs in Perl 6 programs, of note array and hash access, box/unbox operations and various common operations on Int My work also uncovered a problem that could be best addressed with a small language design tweak, and I wrote up a proposal on that I also made various improvements to the optimization infrastructure.

Work in the latter part of July, falling under the current round of the grant, focused mostly on hunting down and fixing bugs. A memory leak bug involving the thread pool scheduler was fixed; it was only problematic in some programs so far, but would have become far more noticeable with the new 6.d await semantics. Others fixes addressed regressions arising from recent optimization work, although in most cases the

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 didn't spend all that many hours during August on perl work. I spent most of my time looking at a bug related to restoring of captures within regex repeats. During the course of that, I took the opportunity to simplify and cleanup

The Grants Committee is accepting grant proposals all the time. We evaluate them every two months and another evaluation period is upon us.

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 did very few hours last month. This was partly due to delays in getting my grant extended, and partly because I was busy with other things.

As I announced at The Perl Conference in Salt Lake City this year, we have completed our project to update the main Perl Foundation website. The new site is now live, with a new design and on a new hosting platform. This project was primarily done by a team of Niagara University students as part of their CIS 480 coursework. This senior level class requires the students to work in

Jonathan Worthington has requested an extension of $10,000 for his Perl 6 Performance and Reliability Engineering grant. This will allow him to dedicate another 200 hours to this work. His previous work was successfully delivered as reported in the latest report. Jonathan writes: "A further grant extension will enable me to continue my work on Perl 6 performance and reliability. The 200 hours I just completed have seen both optimizations

This report describes what I have accomplished in the latest 200 hours of my Perl 6 Performance and Reliability Engineering grant. A new MoarVM specializer plugin mechanism The most significant new optimizations developed in this grant period center around a new mechanism for helping the MoarVM specializer, which optimizes and JIT-compiles hot code, to understand a wider range of Perl 6 constructs. I used this mechanism to speed up: Private

The TPF Board of Directors approved extension of these two grants under the Perl 5 Core Maintenance Fund. Dave Mitchell's Maintaining Perl 5 Grant Tony Cook's Maintaining Perl 5 Grant The Board also approved to allocate $40,000 to the Perl 5 Core Maintenance Fund to enable the above. We thank the TPF sponsors to make these grants possible.

Apologies for the delay; the GC is now conducting our voting for the May/June round and will post results next week. Thank you for your patience. Please look for the next Call for Proposals before the end of the month for the July/August round.
