Hi. I'm setting up distributed simulations on a small farm with tractor. It all seems to work ok, simtracker gets started, the slices are started, synced and doing their job. I also can measure expected time-benefits when simulating on 2 or 4 machines .. BUT .. I can see barely any benefits in memory usage, whether I am doing flip (with pressure solve) or pyro .. It all takes up the same amount of RAM, no matter if I simulate single, on 2 machines or more. Maybe 1-2GB benefit on a 30GB flip sim. Is that expected? I can see that the flip points are half the amount per slice (when distributed on 2 machines), the volumes are half the voxels etc. .. but it still takes the same amount of RAM - which makes the whole point of distributing a bit meaningless. What is wrong here? Did I forget something? The only thing I added in dops (besides the slicing plane) is the gasnetsliceexchange as well as setting the address etc. in distribution tab of course .. as mentioned it seems to work fine (according to simtracker.py). does anybody noticed similar behaviors?
