cupoch v0.1.8 rmm and cuda 11.0 on Ubuntu about cupoch HOT 5 CLOSED

Hi,
What kind of crash is occurring?

from cupoch.

Hi,

I use the master version, that can pass the Cuda 11.0 + RMM and Ubuntu 20.04 build.

But the performance with RMM seems not as my expected so significant. Can you give me any suggestion to improve the performance?

Thank you!

PS:

Here are some test

-- 1.9 million points VoxelDownSample to 60844 points
Open3D+OpenMP 65 ms
Cupoch+RMM 24 ms

-- RemoveRadiusOutliers(100, 20.0), point_size = 60844
Open3D+OpenMP 114 ms
Cupoch+RMM 114 ms

--Estimate Normals(), point_size = 60844
Open3D+OpenMP 59 ms
Cupoch+RMM 28 ms

--Estimate Normals(), point_size = 23733
Open3D+OpenMP 21 ms
Cupoch+RMM 22 ms

You may need to calculate more than 100,000 points to get the speed effect.
Also, using pool memory may make it a little faster.

How to use pool memory ? Example?

Thank you!

In python, you can do the following.
You can also use c++ in the same way.

import cupoch as cph
cph.initialize_allocator(cph.PoolAllocation, 1000000000)
