Could not download forward compatibility package for CUDA

General Usage
1

I am trying to run some CUDA calculations on a cluster and I have a problem with CUDA artifacts. Here is a simple test code, which I run on cluster node.

ENV["JULIA_CUDA_USE_BINARYBUILDER"] = false
using CUDA
CUDA.versioninfo()
println("")
a = CuArray([1,2])
print(a)

The code give me the output, which seems to be correct:

But in addition I have some error messages in the debug output. Is this OK? What is wrong
with CUDA_compat? Can I get rid of this “Downloading artifact: CUDA_compat” messages?

I am not too much into details, but I noticed this.

By having this enabled, I think it will want you to install/direct to your own CUDA artifact?

This is atleast what I get from reading the docs on CUDA

Kind regards

When you work with cluster nodes, usually you have to use CUDA drivers which already installed on the cluster. I have loaded it as modules.

module load nvidia/cuda/11.6u2
module load nvidia/cudnn/8.1.1

As far as I know from docs and forum messages in this case you have to switch off a JULIA_CUDA_USE_BINARYBUILDER and let to use locally built binaries. I can remove this line, but it will try to download all the CUDA packages, not only CUDA_compat.

4

Just if anybody need it: I have found a solution.
In file “~/.julia/packages/CUDA/DfvRa/lib/cudadrv/CUDAdrv.jl” I found an “IF” operator which control the CUDA_compat downloading. Obviously, my CUDA toolkit 11.6 is a bit too old and CUDAdrv.jl try to download compatibility package.

    if getenv("JULIA_CUDA_USE_COMPAT", !hooked && !system_driver_loaded) && _system_version[] < v"11.7"

Solved it easily just switching off JULIA_CUDA_USE_COMPAT environment variable

export JULIA_CUDA_USE_BINARYBUILDER=false
export JULIA_CUDA_USE_COMPAT=false

Why would you disable the attempt to load the forward-compatibility driver? The debug message mentioned that your system isn’t compatible with it, nothing more. It’s just a debug message.

6

User cluster nodes have GPU but have no an internet access. I can install julia packages using a login node but I have no possibility to download when I run code on cluster nodes with GPU.
As far as I found out in message boards - It is not so rare situation

In my case, an unsuccessful attempt to download CUDA_compat takes about 20 additional seconds of compilation time. Thus, I prefer to switch it off. I think that correct solution is just to ask the cluster admin to update CUDA driver, but it could take a while

7

That would be very surprising. Are you sure you’re not confounding the failed download of CUDA_Compat with the artifacts? The latter tries a bunch of time, for each CUDA version, so might take a while to fail all the way. Or is this a feature of your environment (e.g., by timing out connections instead of rejecting them)?

8

I believe that your last suggestion is correct. I have tried to start wget on the node with GPU. Here is the log and there was the very same delay - approximately 20 seconds.
