Unable to reserve FPGAs on KANS or WASH

[Ilya Baldin]

Hello,

We should have FPGAs reserved for our EJFAT project on LOSA, KANS and WASH, however I can only reserve a node with FPGA on LOSA. On the other two it fails (example slice a2630292-21f0-42e1-8e5f-ce3af01b4c04).

Insufficient resources : Component of type: Xilinx-U280 not available in graph node: 6B6G6S3#

It is possible this is happening because I’m requesting 32G RAM on the VM with FPGA, but just wanted to check, since the error suggests FPGAs aren’t available.

Hi Ilya,

Could you please try your slice again? There were leaked slivers. I have cleared them, slice provisioning should work now.

Thanks,

Same problem is back – tried WASH, KANS and LOSA – get a different insufficient error (once it is disk, another it is ram, third time it is Xilinx) but the result is same – can’t create a VM with Xilinx on any of those.

KANS and LOSA both have the FPGA allocated.
WASH seems to have the FPGA available but based on the Core/Ram/Disk requested, the slice might have been rejected.

That’s strange. KANS and LOSA are allocated to our project (EJFAT) and we don’t have anything running there.

Hi Ilya,

I’ve confirmed that the FPGA is currently allocated to a slice belonging to another user. While the FPGA may have been flashed with your bitfile, our current allocation system does not reserve FPGAs for projects based on bitfiles flash requests. If the FPGAs are not linked to a specific slice, they remain available for other users to request and utilize.

We are actively working on enhancing our allocation system and quota management, and I will take your experience as valuable feedback for these improvements. Apologies for any inconvenience this may have caused.

Thanks,
Komal
