Hi, As far as I can tell, you should set the limit in MBytes. So, for 2G, you should have: AddressSpaceLimit=2048 I am using 1GB for some Moose analyses. I benchmarked and got no sign of slowdown.

Re: [Pharo-dev] Pharo (cog) Vm on Windows with 2GB virtual mem
Talking about GBs it makes me wonder , even if the image allowed more than 500MBs if that would be a wise move. Smalltalk is afterall one of the slowest , execution wise, programming languages. In python which is as slow if not slower, the attitude is to move big data to C libs and then interface with these C libs via python. When I see even morphic at times take up to 50% of my dual core 2.0GHz CPU just makes me wonder if cramming 1 GB or more inside the image will end bringing pharo to a crawl for processing that data. So what pharo may need is something that already nativeboost is doing, mapping to C types and access to fast C functions for processing and manipulating big data. Just make it more easier. For example python has numpy (mainly C code, extra types etc) and nowdays also Blaze is emerging as a future candidate. https://github.com/ContinuumIO/blaze https://github.com/ContinuumIO/blaze just a thought. -- View this message in context: http://forum.world.st/Pharo-cog-Vm-on-Windows-with-2GB-virtual-mem-tp4710746p4712155.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
Re: [Pharo-dev] Pharo (cog) Vm on Windows with 2GB virtual mem
Thanks a lot, I added AddressSpaceLimit = 2147483648 To the .ini file and all is working smoothly. FYI, I dont have speed problems with such memory. Of course, If Ill process some big data, Ill wait a while to get the answer, but the same happens in any other lang/platt. Certainty, I can do fast experiments in C, but I dont get all Pharo benefits, like pausing my analysis and resuming it later, such thing in C (or may be any other language) would require to store the intermediate data into files or a database. With Pharo, I dont care about that. Cheers.
