sorting issue with AMD Hawaii GPUs #795

Closed ymhsieh closed 5 years ago

ymhsieh commented 6 years ago

Dear Maintainer,

I faced issues with sorting on GPU based on AMD Hawaii architecture. The issue was reported to AMD (https://community.amd.com/thread/231056), and they suggested I should report the issue to here. So is it possible for you to locating the issue for Hawaii GPUs?

Thanks, Yo-Ming Hsieh

I don't have a Hawaii to reproduce the problem. Does it occur on any other configuration (new AMD GPU, NVIDIA GPU)?

ymhsieh commented 5 years ago

I've tested on NVIDIA GPUs and it is okay. I do not have other AMD GPUs to test it out. I'm willing to give you access to the Hawaii GPUs via ssh on my computers...

@ymhsieh can you help verify if this issue still persists with the current develop branch?

ymhsieh commented 5 years ago

I just tried the "develop" branch and the problem appears to go away.... :-) Thank you ...
