Well done! import taichi as ti
from tqdm import tqdm
if __name__ == "__main__":
ti.init(ti.cpu)
iterations = 10000
for i in tqdm(range(iterations)):
x = ti.field(ti.f32)
fb = ti.FieldsBuilder()
fb.place(x)
snodetree = fb.finalize()
snodetree.destroy() |

But we will still have performance downgrade when the number of allocated and not destroyed SNodeTree is large. Try this. import taichi as ti
from tqdm import tqdm
if __name__ == "__main__":
ti.init(ti.cpu)
iterations = 2
snode_tree_num = 1000
for i in range(iterations):
snode_trees = []
for j in tqdm(range(snode_tree_num)):
x = ti.field(ti.f32)
fb = ti.FieldsBuilder()
fb.place(x)
snodetree = fb.finalize()
snode_trees.append(snodetree)
for snodetree in snode_trees:
snodetree.destroy() |
