[Darren Roark] “The D700s do not have ECC from what I understand, and the Adobe situation may have been from them running a hacked version of CUDA to run on AMD chips.
I’ve melted enough things by taking liberties with settings.”
Thats interesting. Can you provide a link where they mentioned using CUDA on AMD? Thats one hack I have never heard of.

I was just told this was possibly what happened.

[Darren Roark] “The D700s do not have ECC from what I understand”
NVIDIA GTX-series GPUs use non-ECC RAM, and they don’t suffer the glitch. Neither does the nMP/D700 running under Windows on Boot Camp. And lots of users worked around the problem by rendering in chunks or installing external cooling. It seems very clear that there’s a problem with the Mac driver/D700 hardware combination, and the fact that the problem can be mitigated by reducing render loads or using external fans makes a thermal issue possible, if not likely. The bad run of GPUs is a separate issue.

This is some serious FUD. Adobe’s support for OpenCL goes back to 2012.

[Oliver Peters] “[Joe Marler] “Deadpool would be the last feature film that could be edited on a nMP. ”
Why do you say that? Do you mean because of the timeframe or something else?”
I should have said last feature film of that type which required those compute resources. My point was post production is constantly expanding and pushing the limit. If the nMP hardware was somehow fundamentally flawed regarding thermal management in high-end workloads, this would imply that Deadpool’s workload is the end of the line — they reached the limit and nMPs will just burn out like overloaded fuses at that load factor — no matter how many GPUs are replaced.
In fact it is unlikely that the nMP thermal design or Premiere’s use of the hardware is flawed. It was more likely just a bad batch of GPU cards. If it was something deeper, the nMPs would keep burning out under that workload or any future post-production workload of similar type.
The nMP is widely used in many industries. Surely (after three years) if unsafe thermal margins existed at high workloads OR if some software “no man’s land” existed where an app could burn it up, we would know that.

Since Tim Miller is a VFX guy and post was handled in-house, as I remember it, there was interest in working with oversized raw files and live After Effects comps within the timeline. That’s a pretty taxing approach on the hardware and software. By comparison, when Vashi (who consulted on “Deadpool”) tackled “6 Below”, he moved to a PC.

On the other hand, “Gone Girl” and “Hail Caesar” were also Premiere jobs with direct Adobe assistance. Each had pretty solid experiences, though “GG” definitely had some growing pains at the start. Both of these films were cutting on hot-rodded Mac Pro towers (not new MPs) and the Fincher team was partially on PCs for the heavier VFX lifting.
When you compare the workflow on “Whiskey Tango Foxtrot”, they took a much easier approach, with 2K ProRes files and external VFX. Consequently they had a solid experience. I don’t think any of these experiences necessarily relates to software, but rather the approach to workflow taken in post.

[Bill Davis] “Are there legions of burnt up machines out there that nobody’s talking about?”
Take a stroll over to Lift Gamma Gain’s Resolve forum and ask people there what they think of the 2013 Mac Pro…

[Walter Soyka] “Go to any Resolve forum and search for D700.”
I made a similar post before seeing yours. Agreed, the D700 Mac Pro seems particularly problematic for Resolve users.

[Walter Soyka] “This is some serious FUD. Adobe’s support for OpenCL goes back to 2012.”
I didn’t make it up, just sharing info. I was told by someone at AMD this was the case.
I could borrow a page out of politics of late. “There is something going on with Adobe and those AMD GPUs in those trashcans. I don’t know what it is or what Adobe is doing to them but I’d really like to know what’s going on with what Adobe is doing to those GPUs. Something isn’t right!”
Their CUDA performance with certain tasks is still much higher than their OpenCL implementation. This is doubly true in Resolve.

And, taking Darren’s good point a bit farther, Apple and Nvidia have been at odds with one another for a long, long time at this point, guaranteeing that all of us in the video business get inferior GPUs with inferior drivers and inferior performance when we purchase any new Mac computer. When those GPUs could be replaced with superior Nvidia cards no one complained too much, even if you had to eat brand new ATI/AMD cards. If Apple gave a lick about its customers (that’s you guys, folks), they would have figured out a solution to their disagreement Nvidia a long time ago. Anyone care to debate that?

“Maybe they have, let’s see what cards the new machines have when they are announced ?
