Frequently Asked Questions¶
If you have any questions or problem and you can’t find the answer in the documentation, feel free to send an e-mail to firstname.lastname@example.org. An engineer will answer as soon as possible.
The press release says PyTorch and Scikit-learn support. Does this mean general support?
Is it going to be as easy as changing from CPU to GPU?
LightOn Cloud will feature a VM where customers will have access to a CPU, a GPU and LightOn’s OPU. A simple function call will allow computation to be performed on LightOn OPU.
How is the IP treated for algorithms running on your systems?
Any algorithm running on LightOn Cloud is the property of the user. LightOn makes no claim whatsoever on the IP generated by users while using LightOn Cloud.
Is it possible to combine GPU and OPU calculations?
One can combine GPU and OPU computation in the same way as GPU and CPU: by running a part of the computations on the GPU and a part on the OPU. Note that the operation performed by the OPU is not differentiable though.
If you get one of the following errors, there is a hardware issue, please contact support: email@example.com

If I computed a random projection to dimension 10000, can I take the first 1000 columns of this for a projection to dimension 1000?
Yes, sampling any N columns from a projection to a bigger dimension is the same as performing a random projection to dimension N.
