Hi COSIMA team, I am an investigator on a recently awarded Marsden Fund grant , led by Shaun Eaves at Victoria University of Wellington. In the grant we propose to use ACCESS-OM2-025 as part of our experiment plan. We are just trying to get set up on NeSI, the NZ supercomputer, and looking to insta…

Ok… so I couldn’t figure out how to fix my deprecated build that was crashing at the end of CICE5. I did however go back and try again with the spack installation based on Harshula’s instructions: [image] How to build ACCESS-OM2 on NeSI HPC spack How to build …

Yep… if I use a later version of spack such as 1.1, then it can find the newer cmake but it can’t find access-om2. As I’m very much unfamiliar with spack, I will pause for now and look out for guidance once the migration to 1.1 is done.

Hi Dave, At this stage you are dealing with spack internal packages ( https://packages.spack.io ) from the spack builtin catalog, not ACCESS-NRI catalog yet. I guess the error that you see could be (?) due to the deprecation of 2021.2.0 intel-oneapi, idk. I just tried this and it worked out on Leon…

@harshula informed me that the set of versions now is: spack 1.1 intel@2021.10.0 Will try to reinstall everything later on.

Hi @dkhutch , I was able to compile access-om2 with GCC on the NeSI HPC. Here are the instructions: How to build ACCESS-OM2 on NeSI HPC I could not get access-om2 to build with the intel-compiler/2023.2.1 compiler.

Thanks so much Harshula! I will check this out on Monday.

[image] harshula: I was able to compile access-om2 with GCC on the NeSI HPC. Oh so it seems spack 1.1 was needed @harshula ? Or perhaps you didn’t test the older version?

Hi @cbull , Good question! ACCESS-NRI is in the process of migrating to Spack v1.1. Once we do, supporting Spack v0.22 becomes difficult because the SPR (package.py) and MDR (spack.yaml) API has breaking changes. However, if I have time, I’ll see if I can build access-om2 with intel-compiler/2023.2…

Hi Harshula, Sorry for the radio silence! There’s been a lot of end of term assessments to deal with. I am now running through your steps to install the ACCESS-OM2 components on NeSI. Thank you so much for putting these custom steps in place. I will look to test it out in the next few days. I’ll …

Ok so I’m at the point where I’ve got a prototype payu to at least set up a slurm submission on NeSI. But, I’m now running to MPI problems, which I find myself unable to deal with. Errors appear in a form like this: -------------------------------------------------------------------------- PMI2_Ini…

I should mention that separately to this (before I got in touch about spack and ACCESS-OM2), I installed my own version of MOM5 (using the fms_CM2M configuration). In that case I used NeSI-configured compilers, i.e. these ones: module load impi/2021.5.1-intel-compilers-2022.0.2 module load netCDF-F…
