[mvapich-discuss] GPUDirect V3 in MVAPICH2

[Dhabaleswar Panda]

Yes, MVAPICH2 is Kepler compatible. Currently, it supports both GPU Direct 
V1 and GPU Direct V2. Please note that GPUDirect V3 support for Kepler is 
not yet publicly available. The MVAPICH2 team is working on the GPU Direct 
V3 support. Initial results of the design were presented at NVIDIA GTC 
2013. You can find the presentation at the following URL:

The video recording of this presentation is also available from the 
following URL:

The design in MVAPICH2 to support GPU Direct V3 is continuing. The support 
will be available in upcoming MVAPICH2 relese as soon as the GPU Direct V3 
support becomes publicly available.

Hope this information helps.

Thanks,

DK
