Any comments from Moderator(s) on this post I’m replying to? Regarding the bug report?..

My return-window is almost up now, however, so I may just need to file a return for my DGX Spark–given that time has essentially run out–for me to continue doing any further troubleshooting on this matter.

Anyway, thanks again to all for the help, everyone, regardless. Hope this thread is useful for others, moving forward!

Was a partial log created when you attempted the log collection? Even if it didn’t finish, any information would be helpful for debugging

Hi All,

I’ve returned my DGX Spark. Thanks for trying to help, though!

THIS IS A REAL PROBLEM AND A FRUSTRATING ONE. TRIED ALL CABLE CHANGE, MONITOR CHANGE SHENANIGANS, NOTHING HELPS!!! Would really wish someone from NVIDIA would help on this.

Its a new product and frustrating to see the support level on this. Feel sorry for urmom69@ (funny name btw) that they had to return. Unfortunately I’m stuck with mine as it has crossed the 30 day period :D.

If you would like help, please do the following.

  1. Be ready to use whatever system you used to post this forum or another system to ssh into your DGX Spark
    1. If you need help with ssh, have a look at the following: Set Up Local Network Access | DGX Spark
  2. Get the system in a repro state with the monitor connected
  3. Over ssh, run sudo nvidia-bug-report.sh
  4. Use scp to copy the compressed generated log file over
    1. For information on sftp, refer to SCP and SFTP - ArchWiki
  5. If you run into issues with the above steps, lets go over the issues encountered.

Thanks for your cooperation.

urmom69 didn’t think that would help him, but please know, this has helped me immensely.

I’m trying to build my DGX WORKstation (emphasis on “work”) and I really benefited from your comments. Your monitor, the Barrier solution, and other items you’ve described have helped me pick out all of my components. And they’re on the way.

Of course I’m excited, but if you’re interesting I’m getting the following. Any comments or suggestions are welcome.

• The centerpiece is the DGX Spark of course, with a 4 TB NVMe setup and 128 GB of unified memory. That’s the main compute node. It’s capable of 1 PetaFLOPS, a quadrillion operations per second (my MacBook might be capable of 2.5-4 teraFLOPS, so the Spark is 20,000 times more computationally powerful)
• I’m adding two 8 TB SanDisk portable SSDs—one for storing models and datasets, the other for checkpoints and various experiments.
• For central storage, I’ve got a 4-bay NAS enclosure. I’ll be running it in RAID 5 or RAID 6, so that gives me a good balance of redundancy and usable space, around 24 TB usable.
• There’s also a 10 GbE network switch to keep everything communicating quickly and a UPS for clean shutdowns in case of power issues.
• Finally, I’ve got a 34-inch Dell monitor, a Keychron mechanical keyboard, and a mouse to round out the workstation.

Again, suggestions are welcome.

I’m glad you found my notes helpful, John! Sounds like a great setup! :)
