NativeBoost : optimisation of the machine code generation

by Thomas Bany

Hi everyone, I'm trying to reduce the computation time of the following pseudo-code: - memory allocation (~40 doubles) - object heap to C heap copying - NativeBoost call (nbCall:) - memory freeing The time profiling results are bellow: - 24*3600 calls : > 1 minute - 24*3600 calls with only memory allocation and copying : < 1 second - 1 call with a 24*3600 loop inside de C code : < 1 second So it appears that the very coslty step is the transition from Pharo to C. And I was wondering if it was possible to drasticly reduce this time by doing something like, generate the the machine code once and call it multiple time ? Thanks in advance ! Thomas.

Rewrite Tool

by Mark Rizun

Hi guys, After working on refactorings, I started implementing Rewrite Tool, which provides GUI to create rewrite rools. At this point it's in early stage, but you can take a look at it now. Info on blog: http://myfuncoding.blogspot.com/ Download: http://smalltalkhub.com/#!/~MarkRizun/RewriteTool Simple example on YouTube: https://www.youtube.com/watch?v=ZY8QfIo-A6E&feature=youtu.be&a It's my first video, that I recorded, so don't judge me:) As always, feedback is welcome!

The one on the right is the Cancel button. Or, you can bring up the halos on the window and close it that way. Or, you could (but it's not efficient in this case) do it programmatically, but no you should never have to quit via the VM for this kind of problem.

Re: [Pharo-users] Versionner and issue tracking

by Sean P. DeNigris

Evan Donahue wrote > pharo --version returns "3.9-7" and the image's about pane lists "Latest > update: #30848" Is either of those the relevant statistic? The first one is the VM version. The second is what I was after. In Pharo's system, #30848 means version 3.0, update 848. I tried to recreate your problem in #30848. Background: The window you're describing references issue-tracking-like things because it started life as part of our Pharo contribution process and ended up doing double duty in Versionner because its quite useful. However, it is somewhere geared to the contribution use case of always committing to one repository (the Pharo inbox) Because of this history, right now all packages in the project have to be associated to a common repository to commit via that window. On the right side of the window, just below center, there is a "Remote" dropdown. If your project's packages share a common repository, select it here and you will avoid the Issue# dialog. If not, use the MC Browser to commit them individually the old fashioned way for now.

I assume the usage is pharo on the backend and bootstrap on the front end ? Very nice. Definitely a good solution for mobile devices.
