| 35 | | Now, to explain the difference between the number astrobear.log reports for the total info allocations, and the memory being reported as actually being used by the cluster in bluehive.log, we add the baseline memory to the info allocations. This gives, .2+1.6=1.8 GB, .2+2*1.6=3.4 GB, and 50+8*1.6=62.8 GB. The difference between the info+baseline and the actual used memory is largest for the simulation running on more nodes |

The difference between the info+baseline and the actual used memory is largest for the simulation running on more nodes (62 GB compared to 80 GB). The difference might be due to redundant calculations (ghost cells) and parallelization. |
