Hi,
Roughly speaking, we need the sum of the total movie size,
the extracted particle size and some working area, which is much
smaller compared to the other two.
The total movie size is movie_width * movie_height * frame * 4 (float).
The extracted particle size is number_of_particles_in_a_movie *
box_width_in_movie * box_height_in_movie * frame * 4.
In typical (non super-resolution) datasets, this is up to 20 GB.
So I usually run 2 MPI processes per 64 GB node, but it is
safer to run only 1 process per node if you have hundreds of
particles with overlapping boxes.
Best regards,
Takanori Nakane
