ChestStack

Finding tall stacks of chest minecarts.

Task layout

We have the total chunk area:
x: -1875000 -- 1875000
z: -1875000 -- 1875000

Divided into batches of 100x100 chunks:
bx: -18750 -- 18750
bz: -18750 -- 18750

By encoding these coordinates as (bx+18750)*37500 + (bz+18750), we get the following range of possible task IDs: [0, 1406287500]

CPU-only app

Compile using

g++ carver_reversal.cpp chest_sim.cpp cpu_checker.cpp -O3 -o cpu_checker

then run with:

./cpu_checker --start [task_id] --end [task_id] --threads [num_threads]

where --start defines the inclusive start of the task id range, and --end defines the exclusive end.

CPU-GPU app

Compile using

nvcc hybrid_checker.cu -O3 -o gpu_checker 

then run with:

./gpu_checker --start [task_id] --end [task_id] --threads [num_threads]

where --start defines the inclusive start of the task id range, and --end defines the exclusive end.
