Thank you for your help! I have installed the updated version of Julia and when running it appears to be Segfaulting when trying to add CUDA. I will open an issue with them if I cannot figure out how to solve it. Thank you again
from oceananigans.jl.
I have been running on the system Julia for these, I attempted to do my own install but I do not think I ended up doing much with it. I believe gcc
is a dependency for the subsequent modules as for example when I run:
module --force purge
module load ncarenv/23.10
module load ncarcompilers/1.0.0
the last line returns
Lmod has detected the following error: These module(s) or
extension(s) exist but cannot be loaded as requested: "ncarcompilers/1.0.0"
Try: "module spider ncarcompilers/1.0.0" to see how to load the module(s).
which does not happen if I include gcc
. I was also able to run my code without netcdf!
from oceananigans.jl.
What is your versioninfo()
? How did you install Julia?

I would recommend using juliaup
to manage your Julia installation.
from oceananigans.jl.
I checked and it is showing that I am running version 1.9.2. I just installed juliaup and made sure Oceanostics was updated. I got the following error
[36147] signal (11.1): Segmentation fault

So I reduced my code to be just
using Oceananigans
and the code gave the following error

I have been trying to make sure that everything is up to date, and I am running on Julia version 1.9.2. My code is just
using Oceananingans
as I have been trying to get the library to load properly. Does anyone have any experience with this error or does it make things any clearer?

Info Packages marked with ⌃ and ⌅ have new versions available, but those with ⌅ are restricted by compatibility constraints from upgrading. To see why use `status --outdated -m`
from oceananigans.jl.
I don't know if this helps to make the issue clearer, but I just re-ran the code for just
using Oceananigans
and it executed without error. I ran it again to see if it was just a fluke and I got the following error:
The following have been reloaded with a version change:
1) cuda/12.2.1 => cuda/11.8.0
[59837] signal (11.1): Segmentation fault

Could it be an issue with the computer loading Oceananigans.jl with a bunch of extra functions?
from oceananigans.jl.
More information, I tried changing Oceananigans.jl builds by running in Julia
] add https://github.com/climate-machine/Oceananigans.jl.git
and I ran my code and it loaded fine the first time, but again it had a segmentation fault on the rerun. Similarly, when I executed
] add Oceananigans
it ran the first time then got a segmentation fault on the second run again. Could this not be an issue with Oceananigans.jl but with how I am running my code on the GPU?
from oceananigans.jl.
Just to clarify things a bit for you @loganpknudsen --- your error says
ERROR: LoadError: Failed to precompile Oceananigans
this means that the segmentation fault occurs during precompilation of Oceananigans
, which occurs before any code you have written executes. That's why the error comes from "line 1" of your script (is that where you write using Oceananigans
?)
Another clue is the text
[52922] signal (11.1): Segmentation fault
in expression starting at /glade/u/home/knudsenl/.julia/packages/Oceananigans/M82LU/src/Oceananigans.jl:129
That says the error comes from line 129 in the file src/Oceananigans.jl
. Going to that line on main
branch we find:
Oceananigans.jl/src/Oceananigans.jl
Line 129 in d6e63e5
so there's something wrong with your CUDA / how it's loaded.
The best course of action is probably to update to julia 1.10 first of all rather than using julia 1.9.2.
Next, see if you can simply write using CUDA
rather than trying to run your whole script. If you can get that to work (better yet if you can use some of CUDA.jl
on a GPU on derecho then move on to simply writing using Oceananigans
and trying to build a grid on the GPU. If that succeeds move on to your script.
from oceananigans.jl.
Thank you for your help! I have installed the updated version of Julia and when running it appears to be Segfaulting when trying to add CUDA. I will open an issue with them if I cannot figure out how to solve it. Thank you again
@logan can you link the CUDA issue here please?
Also, if you haven't tried, erase everything on your $JULIA_DEPOT_PATH
(really to be safe you should make a backup of everything there first) and then run the same script you've been running with using Pkg; Pkg.instantiate()
on the first line. This should "re-install" all the packages from scratch.
For context $JULIA_DEPOT_PATH
by default is ~/.julia
, I think, and that's where julia stores the package files it downloads. The hypothesis here is that at some point some package download/compilation went wrong and you have some broken code there.
from oceananigans.jl.
Okay, here's the CUDA issue: JuliaGPU/CUDA.jl#2453
from oceananigans.jl.
So I removed ~/.julia
and ran the instantiate before and I got the following output

Thank you to everyone who took the time to respond to this issue! I am still unclear on what exactly was driving the error I was getting, but I was able to fix it by creating a new environment in a clean directory and running the following modules on Casper for the UCAR HPC resources:
module --force purge
module --ignore-cache load ncarenv/23.10 gcc ncarcompilers netcdf
module --ignore-cache load cuda
module --ignore-cache load julia/1.10.2
and then running my script. Thanks again for all the help!

Thanks for posting the solution. What does the ignore-cache
flag do? And how did you get to it?
from oceananigans.jl.
I am not certain what the ignore-cache
flag does, I borrowed the module loading sequence. I am pretty it ignores previously loaded modules with the same or similar name.
from oceananigans.jl.
What was the failing workflow / how was it different than this?
from oceananigans.jl.
The module loading sequence I was running was before that didn't work were
module --force purge
module load ncarenv/23.10 gcc/12.2.0
module load ncarcompilers/1.0.0
module load netcdf/4.9.2 openmpi/4.1.6
module load julia/1.9.2
module load cuda/12.2.1
if needed I can see if I can find the versions of the modules that ended up working. There are no other major difference in how I load in the packages or Julia. Let me know if you have any questions
from oceananigans.jl.
Okay interesting!
I'm not sure why you would need gcc
. Have you tried omitting that?
Also, did you try installing julia yourself? There could be some benefit in using the system Julia via module load julia/1.9.2
, but this would mostly have to do with compilation speed (not execution speed) I think. If you have found discrepancy between the system Julia vs your own Julia install that'd be interesting to hear about...
You could also let julia handle netcdf --- again, I'm not sure if this would have performance implications or not, but it might provide faster way to get up and running if you are simply trying to run scripts. Julia's package manager should be able to automatically detect and install netcdf appropriate for the system, I think.

Ok, good to know!
