Gpu and multiple processes

Accelerated Computing CUDA CUDA Programming and Performance

Hello,
I have a Tesla C2050, I know host multiple threads can use this device Simultaneously.
I ask, Can multiple processes (host) use this device simultaneously?
Thanks

I have a gtx 470, which is same chip as the Tesla C2050.

I can run several instance of cuda sdk example (for example, 3 nbody). And I can run several instance of my own application.

Yes, but the performance is worse with 20 (for example) jobs simultaneously. I fear the kernel of the jobs are not run simultaneously (like kernel of the thread), but sequentially. There is also a way to run different kernel of different jobs simultaneously?

According to the programming guide, no. Only kernels belonging to the same context can run concurrently.
