1) Message boards : GPUs : Trouble getting BOINC to recognize second NVIDIA GTX 1070 in MacPro 5,1 (Message 97039)
Posted 24 Mar 2020 by Profile David Riese
Post:
I have diagnosed the problem. MacOS 10.13.6 High Sierra does not load OpenCL for the second GTX 1070, even though the System Profiler acknowledges the presence of the second GPU and the second GPU can successfully drive a monitor. However, MacOS 10.12.6 Sierra DOES load OpenCL for the second GTX 1070 and BOINC is capable of utilizing both GPUs.

It is possible that this "bug" is specific to 10.13.6, as my BOINC recognizes two AMD RX 580 eGPUs connected to an iMac 18,1 running MacOS 10.14.6 Mojave. But, the conspiracy theorist in me believes the "bug" is specific to the combination of MacOS beyond Sierra and NVIDIA GPUs, as it is well evidenced that Apple and NVIDIA are no longer cooperating as they once did. More importantly, eGPUs that utilize the NVIDIA GPUs with Maxwell architecture and beyond are officially incompatible with Macs.

It's a pity, as there are some really great NVIDIA GPUs that I would love to run in my MacPro 5,1 boxes or as eGPUs connected to my more contemporary iMacs, Mac Minis, and MacBook Pros.

My MacPro 5,1 has two NVIDIA GTX 1070 GPUs. One is connected to the internal power supply. One is connected to an external power supply. I can connect either GPU to a monitor (hot swappable). See links for photos:

However, BOINC only recognizes one of the two GPUs. I don't have any problem getting BOINC to recognize two NVIDIA GTX 750Ti GPUs. Any idea on how I can get BOINC to recognize the second GTX 1070? Thanks in advance for any advice. Log file excerpt is below:

Now I am having a different problem. When running only Collatz, on an 8-core MacPro with 87.5% of the cores (7 cores) allocated to BOINC, frequently BOINC runs 7 CPU tasks and 1 GPU task. How do I force it to run on both GPUs (NVIDIA GTC 750Ti).

I apologize in advance for starting a new thread, but I was unable to post this to the existing "Different projects for 2 opus" thread.

I have two MacPro 3,1 (Early 2008) computers with two GPUs each (from NVIDIA and ATI). They are running OS X 10.11 and Boinc 7.6 and 7.8. I wanted to crunch Collatz tasks using the NVIDIA GPU and Rosetta, Seti, and Einstein tasks using the ATI GPU. The cc_config.xml file below allows me to do so. This configuration allows tasks to be queued independently for each GPU; in other words, when the first GPU finishes a task, it does not need to wait for the second GPU to finish its task before it (the first GPU) starts a new task. Happy crunching!

I apologize for not exhaustively searching the forum before posting this question. Found the answer in the following thread: "Different projects for 2 gpus". Will see how it works, although I am a bit nervous about the fact that this thread indicates that the tasks are loaded in pairs, meaning that after one GPU finishes its task it will wait for the other GPU to be finished before tasks are loaded for each of them. Hmmmm ....

I have four AMD Radeon HD 5770 and 5870 GPUs (Mac Edition) that I pulled out of 2008 MacPro 3,1 units when I installed NVDIA GeForce GTX (680, 770, 960...) GPUs. I use NVIDIA GPUs to crunch Collatz tasks. However, I cannot crunch Collatz tasks using the AMD GPUs. Is there any way to simultaneously crunch Collatz tasks using an NVIDIA GPU and Einstein tasks using the AMD GPU in the SAME MacPro 3,1? TIA!

It appears that Collatz went down at approximately 06:00 UTC today. Still not back up.

Collatz came back up on 3/16, but went back off on 3/21. No big deal, as I have 4-6 days of C@H tasks remaining in the queues.

Update on my previous message 60688.

Now that Collatz is back up, my backlog of completed tasks has been uploaded and I received plenty of new tasks to crunch. I did not lose any completed work units, either; my crunching activity (~1.1 M/day) for the last 9 days (2/26-3/07) is within 3% of my activity for the preceding two weeks (2/12 to 2/26).

I am going to try to continue to treat Collatz and Slicker with patience. I think they deserve it.

Oddly enough, Collatz is still accepting completed tasks. So, I am going to keep crunching my Collatz work units until I run out of them. Hopefully, by that point Collatz will be back. In the meantime, I am going to look for alternatives. Not too many projects run on GPUs under Mac OS, particularly some of my older slower GPUs like NVIDIA GeForce 320M, NVIDIA GeForce 9400, and NVIDIA GeForce 8800 GT.

Again, it would be a shame if Slicker pulled the plug on the project. Once we get passed the Martin Luther King Jr holiday, I will look to see if Slicker gives us some sign that the project is coming back online.
