Usage of OpenCL backend instead of PTX for tornadovm-nvidia-openjdk

[andrii0lomakin]

Good day.
May I ask you to provide reasons why only OpenCL backed is used for tornadovm-nvidia-openjdk docker image?
Shouldn't the PTX backend be available, too?

hi @andrii0lomakin, as far as I can tell it is just that the dockerfile that is used to build the container does not build TornadoVM has used only the OpenCL argument. We can change that for the next release (end of September). Thanks for pointing it out.

Thank you @stratika

Our OpenCL images extend the nvidia/opencl base images.

When we built these images, PTX SDKs were not available for the OpenCL image. Alternatively, you can extend from the nvidia/cuda image:

Hi @jjfumero
Yeah, sure, I understand it.

It was mainly an FYI discussion. To point out this behavior, you may want to change.
