Hi all,
Our group just installed a Tesla S1070 on a Linux-64 bit operation system. I run the example “deviceQuery” in SDK package and found there are only 2 GPUs detected.
Here is the message:

I thought Tesla S1070 had 4 GPUs, why I only saw 2? Is there something wrong with my hardware connections? Thanks for any advise.
