Update: January 15, 2016 Thank you for your candidness, patience and feedback. We're going to delay the implementation for now - we'll be back soon to open some more discussions.
So it's not been taken off the table, but it probably won't happen anytime soon.
As for CUDA - it is almost directly inferior to OpenCL. CUDA's prevalence is largely due to NVIDIA's attempts to jam it down every available throat.
Not even close. CUDA came out well before OpenCL (CUDA in June 2007, OpenCL 1.0 in August 2009), and has remained ahead features, tools and stability-wise ever since. (yes I have used both). I would really like for AMD + OpenCL to be better than NVIDIA + CUDA, but I've been wishing for that for the last 6 years and it has yet to happen.
I've never used it, but TBB flow graph does have graphical tool as well (https://software.intel.com/en-us/articles/flow-graph-designer). Looks like a two-part profiler and designer -- in their words, the design component "provides the ability to visually create Intel TBB flow graph diagrams and then generate C++ stubs as a starting point for further development."
That tensorflow graph tool does looks pretty nice though
There have been tools to do this in the past but, they have frequently been clumsy internal tools and geared towards a specific set of algorithms
Intel TBB's flow graph does a pretty good job of this.
Oh, sure, they might get a little bad PR, and the stock might slip a little. But that asshole executive who decided security was too costly? It's not his data being stolen, and it's not him who has to deal with it.
While I agree with the overall sentiment, in this specific case the hackers look to have grabbed the full source of all the parent companies' websites, and the CEO's emails... which they recently released.
