Severe one-way RDMA performance regression on ASUS Ascent GX10 with kernel 6.17.0-1029-nvidia

Claesbas · August 6, 2026, 7:46am

Hi everyone,

I would like to share an issue I found while connecting two NVIDIA GB10-based systems for distributed inference.

My setup consists of:

One NVIDIA DGX Spark
One ASUS Ascent GX10
Two direct 200 Gb/s ConnectX-7 links
RoCE v2 and NCCL
Tensor-parallel vLLM inference across both systems

The network configuration appeared correct, but performance was severely asymmetric.

Observed performance

With the ASUS Ascent GX10 running kernel:

6.17.0-1029-nvidia

RDMA Write performance was:

DGX Spark -> ASUS GX10: approximately 13.2 Gbit/s
ASUS GX10 -> DGX Spark: approximately 111.6 Gbit/s

The same directional asymmetry was also visible with TCP testing.

We tested:

Both ConnectX-7 links
1, 4 and 8 QPs
RDMA Write, Read and Send
PCIe link width and speed
IRQ affinity and queue distribution
ConnectX firmware
IOMMU/SMMU configuration
PCIe AER error counters

Both systems used identical ConnectX firmware:

FW Version: 28.45.4028
PSID: NVD0000000087

PCIe was operating correctly at:

PCIe 5.0
32 GT/s
x4

No PCIe or AER errors were reported.

Resolution

I installed and booted the ASUS Ascent GX10 with:

6.17.0-1026-nvidia

Without changing the network, firmware, RoCE or NCCL configuration, RDMA Write performance immediately increased from approximately:

13.2 Gbit/s

to:

111.7 Gbit/s

The result remained stable after reboot.

This strongly suggests a kernel regression in 6.17.0-1029-nvidia affecting incoming RDMA traffic or PCIe DMA writes on the ASUS Ascent GX10.

For now, I have configured the system to boot kernel 6.17.0-1026-nvidia and placed the 1029 kernel packages on hold.

Has anyone else observed this issue on an ASUS Ascent GX10, DGX Spark or another GB10-based system?

It would be helpful if NVIDIA could confirm whether this is a known regression in kernel 6.17.0-1029-nvidia.

I am supposed to get my correct QSFP cable today, can you give me the command you use to test the RDMA performances? I have two GX10.

Hi, there’s a lot of guides on this . DGX-SPARK/dual-spark at main · Sggin1/DGX-SPARK · GitHub is one I created after got my dual setup working well, you can scroll to bottom too and it has links to others in the Acknowledgments. typical setup is a single cable , max bandwidth is 200Gb/s it breaks up into 4 channels on 2 pci if memory serves. almost any AI can config it for you just point to any of the guides. Using same username on both is very helpful , jumbo frames 9k, rdma… good luck

Thanks @sggin1 , I already had the link configured, but with a 10G SFP+ ;)

@Claesbas I confirm the issue. I had to revert to 6.17.0-1026-nvidia.

On 6.17.0-1026-nvidia:

Thanks for finding that, I would have been disappointed with my new cable…

foogitiff · August 6, 2026, 6:04pm

Well yeah, I ask the test to run for 30 seconds, so less speed → less iteration done in the allotted time.

@Claesbas it would be interesting to see if it only impact the GX10 or it’s only an issue if one of them uses the 1029 kernel? Can you try your benchmark the other way?

aniculescu · August 6, 2026, 9:29pm

Thank you for flagging this. Can you share your firmware version? Please share with me the output of sudo dmidecode -t 45

Claesbas · August 7, 2026, 6:40am

Sure! I used “ib_write_bw” from perftest.

On the receiving GX10:

ib_write_bw
-d rocep1s0f1
-i 1
-x 3
-F
-q 8
–report_gbits

Then on the sending GX10:

ib_write_bw
-d rocep1s0f1
-i 1
-x 3
-F
-q 8
–report_gbits
<IP_OF_RECEIVING_GX10>

In my setup the RDMA interface is “rocep1s0f1”, GID index is “3”, and the direct-link IPs are “10.70.0.1” / “10.70.0.2”, so for example from my first machine to the second I use:

ib_write_bw -d rocep1s0f1 -i 1 -x 3 -F -q 8 --report_gbits 10.70.0.2

With kernel “6.17.0-1029-nvidia” on the receiving GX10 I was only getting around 13.2 Gbit/s. After booting that machine with “6.17.0-1026-nvidia”, the exact same test gives around 111.7 Gbit/s.

Would be very interesting to see what you get with two GX10s, especially which kernel versions you are running.

Ok, I updated again this morning everything, rebooted, and now I cannot reproduce…

You should definitely update the firmwares, it seems you are several versions behind.

I had an almost identical problem a couple of weeks back. Good news is the fix was relatively simple. Note my set up is going via a switch. Exactly as recorded by my AI … which also admitted it spent a lot of cycles hypothesizing and chasing dead-ends until I suggested the reboot.

The cause: spark-01 booted with no carrier on the CX7 (spark-02 was down at the time, so the link was dead), and the cable came live afterwards. The mlx5 driver initialises against a dead port and never fully recovers its transmit path on later link-up.

    │            condition            │  01 → 02  │ 02 → 01 │
    │ cable hot-plugged after boot    │ 13.3 Gb/s │ 97.98   │
    │ after reboot, link live at boot │ 97.98     │ 97.98   │

Inferred mechanism: DMA writes (receive) are posted and stay fast; DMA reads (transmit) are non-posted an latency-sensitive, so only the outbound direction suffers.

The fix was a reboot with the link already live

I hope that helps in some way!

I think you are on to something @wentbackward, I had to reboot both machines today and perf were awful:

I have tried this exact scenario on an FE Spark and was not able to reproduce. @foogitiff Are you also running on an ASUS GX10?

foogitiff · August 11, 2026, 7:35pm

Yes I have two GX10

Hi, @Claesbas what is your sparks’ connection, back to back or via a switch?

Claesbas · August 12, 2026, 5:58pm

They are connected via a 0.5m https://www.fs.com/eu-en/products/115634.html - looking at the backs its the right one on both.

Claesbas · August 12, 2026, 6:06pm

I really thing it is connected to the “rebooting”. I forgot to even try that.

So my guess is that its some “bug” when connecting the cable in some circumstances, it get stuck one way in slow mode - rebooting both devices fixes it with the cable attached.

Its just my hunch.

I had issues with fs com 0.5m cable. Switching to Amphenol resolved it.

huawenl · August 13, 2026, 5:50am

so it seems for both back-to-back connection and connection via switch the issue may happen then can be fixed by a reboot in both Sparks. here some more questions may help to isolate whether it is hot-plug issue or not, can you help to recall?

whether you plugged in the cable at the time one/two Spark were running?
After you plugged before you ran test was there reboot?

Thanks.

I am afraid I cant remember in detail. I think my first spark was turned on. I put the new on top and connected the cable (top first the bottom), then turned the top one on.
