test_svd_dense_opencl fails on Ubuntu 20.04 LTS using NVIDIA OpenCL on AWS g3s.xlarge instance #3147
Description
Test 340 test_svd_dense_opencl fails with ArrayFire compiled on Ubuntu 20.04 LTS using NVIDIA OpenCL on AWS g3s.xlarge instance.
Description
- Did you build ArrayFire yourself or did you use the official installers?
[ArrayFire was built from source code on AWS EC2 g3s instance (NVIDIA Tesla M60 GPU)] - Which backend is experiencing this issue? (CPU, CUDA, OpenCL)
[OpenCL] - Do you have a workaround?
[No] - Can the bug be reproduced reliably on your system?
[Yes] - A clear and concise description of what you expected to happen.
[Expect that Test 340 will pass successfully] - Run your executable with AF_TRACE=all and AF_PRINT_ERRORS=1 environment
variables set.
[Variables were set, but no additional output was produced] - Screenshot or terminal output of the results`
