Nice find - thank you for posting it. Its a good "real world" overview and strongly makes the point that talk of a "brave new world" of OpenCL computing with all chatting happily to each other is a ways off yet. At the same time it was bullish about the eventual outcome. If the internal thoughts of the various OpenCL teams are similarly bullish and long-term cooperative minded, its looking good.

That said, it will still allow more portable code for those projects without the resources to create versions for the two MFGR's APIs ... ID: 7742 · Rating: 0 · rate: / Reply Quote

So i guess its gonna be cuda and cal along this long road ID: 7759 · Rating: 0 · rate: / Reply Quote

As i read this i think there is a super long road to go before its gonna be usefull. So i guess its gonna be cuda and cal along this long road There will be a place for CUDA and CAL (or their successors) forever ... OpenCL will complement them, never replace them ... I suspect only those projects that cannot afford to invest in the "hand-coding" needed to use the CUDA or CAL APIs will use OpenCL. ID: 7769 · Rating: 0 · rate: / Reply Quote
