[ANN] Pharo TechTalk Feb 20: The Colony
by Marcus Denker Feb. 21, 2020

Feb. 21, 2020

*** this Thursday *** A regular chat about Pharo. Happens on Discord. This month a bit a special TechTalk, not about Pharo but about a tool that might be interesting for us to use. Topic: The Colony https://colony.io <https://colony.io/> Introduction to "The Colony", a new platform to Organize and Incentivize Collaborators, Contributors, and Communities. Short demo, followed by some Q&A, help to get people onboarded. https://association.pharo.org/event-3697011 <https://association.pharo.org/event-3697011> 20 Feb 2020 â¢ 1:30 PM - 2:30 PM (EST) NOTE: this is EST time, for Europe, this is 19:30 (the easiest is to download the calendar entry)

IIUR, the size cannot be changed at runtime so there are two VM parameters. The parameter 44 gives the current size of the Eden while parameter 45 should be used to set the desired size of the Eden. > > What I did was that I executed this: > > $VM Pharo.image --no-default-preferences eval --save "Smalltalk vm parameterAt: 45 put: 67108864.

"67108864" > There is quite a large margin between the two. > Alas this discrepancy is historical and semantic. In the old V3 memory manager there was only old space and eden, and one could set the size of eden dynamically because it was simply âthe region at the end of old spaceâ, marked by a base/limit paid of pointers (IIRC; Iâm on my phone so I might have details wrong). In Spur eden is actually one of three regions of new space, the other two being the two survivor spaces, past survivor space and future survivor space (past space and future space for short). Past and future space are the same size and swap after each scavenge, which empties eden and past space, copying survivors into future space, tenuring overflow to old space and then making future space the new past space. The ratio of each survivor space to eden is 1 to 5, i.e. eden is 5/7 of new space and the survivor spaces are 2/7 of new space (currently this ratio cannot be changed). What we really want to do is set the size of new space but the parameter historically referred to v3âs eden. So Spur interprets parameter 45 as setting the desired size of (all of) new space but accurately reports the size of eden for parameter 44. (49546912 / 67108864) â (5/7). So the vm parameter methods should state that vm parameter 45 in v3 sets the desired size of eden and in Spur sets the desired size of new space, while in both, parameter 44 reports the size of eden. And yes, this is a bit of a mess. IIRC there is another parameter that reports the size of new space, but it may report the occupancy of new space.
