Hello Gadgeters
I am trying to make a DM only simulation with 512^3 particles in a
100Mpc box. I am running it with mpi over 8 nodes, 4 processors per node
and the processors are 2GB.
The parameters I have that are relevant to the memory usage are:
PartAllocFactor 1.6
TreeAllocFactor 0.8
BufferSize 100
But Gadget gives me the message,
failed to allocate memory for `P' (921.6 MB).
task 10: endrun called with an error level of 1
I don't know why it can't allocate this memory or what it is spending
all the memory on, how can I fix this problem?
Thanks
Holly
