Hi,
We have some Tesla C870 cards within our department that I would like to use for applications involving streaming. However, when I query them I get the output attached below. This appears to show that these cards are only able to use Cuda 1.0, and so cannot take advantage of streams. Is this correct? For the record, we are using on of the 1u units, attached to an HP server running Red Hat enterprise 5.2.
Any thoughts/clarification would be appreciated.
Daniel
