Hi,

I am trying to run a 64^3 dm+gas simulation. My Memory factors are:

PartAllocFactor 3.0
TreeAllocFactor 2.0
BufferSize 100 % in MByte

But The job crashes as below:



Allocated 20 MByte for particle storage. 80
Allocated 10.5 MByte for storage of SPH data. 84

reading file `/Users/shankar/gadget/Gadget-2.0.6/ICs/lcdm_gas_ic.dat' on task=0 (contains 524288 particles.)
distributing this file to tasks 0-3
Type 0 (gas): 262144 (tot= 0000262144) masstab=0.529289
Type 1 (halo): 262144 (tot= 0000262144) masstab=3.44038
Type 2 (disk): 0 (tot= 0000000000) masstab=0
Type 3 (bulge): 0 (tot= 0000000000) masstab=0
Type 4 (stars): 0 (tot= 0000000000) masstab=0
Type 5 (bndry): 0 (tot= 0000000000) masstab=0

reading done.
Total number of particles : 0000524288

allocated 0.0762939 Mbyte for ngb search.
Allocated 34.763 MByte for BH-tree. 64

domain decomposition...
NTopleaves= 225

No domain decomposition that stays within memory bounds is possible.



What is 80, 84, 64 that appear above?
