Hi Cip Cool to see you trying the 64 bits :) Your feedback and cases are really nice for Pharo. Stef
Hi all,
I'm very happy to see that the 64 bit Pharo vm is progressing. I've even managed to get a ~6.85 GB heap allocated (see http://bit.ly/2lbp8n6). This is great!
There seems however to be a small problem with the #shallowCopy message, which is 2.63 times slower on the 64bit VM (image/vm details bellow).
The bench that I used is a simple random graph analysis tool that is intended to do a lot of random memory accesses on big heaps, which is accessible at http://www.smalltalkhub.com/>#!/~CipT/PlugMC In this case I expect the execution time to be dominated by the Set implementation (which is the case with pharo 5 -- see http://bit.ly/2lbzJhd), and not by the array copy (see http://>bit.ly/2kvbqvy).
Is this a 64bit limitation, or only a feature "not yet available" ? Where can I access the latests versions of 64 bit pharo image and vm ?
