This repository contains a set of EasyBuild recipes (*.eb) to compile ParaView+ANARI and VisIt+ANARI and their dependencies for the VISTA supercomputer (NVIDIA GH200, aarch64) using the foss/2024a toolchain.

The install is non-root and isolated under a directory you control.

EasyBuild automates building HPC software stacks with consistent prefixes, modules, and dependencies. You provide an "easyconfig" (.eb) file; EasyBuild builds, installs, and generates a module for you. Use --robot to auto-resolve dependencies from local .eb files.

#!/bin/bash
# choose your working area
cd ~/scratch/easybuild

# install prefix and module path
export EASYBUILD_PREFIX="$PWD/easybuild"
export MODULEPATH="$EASYBUILD_PREFIX/modules/all:$MODULEPATH"

# create & activate a Python venv (one time only)
# python3 -m venv "$PWD/venvs/eb"
source "$PWD/venvs/eb/bin/activate"

# upgrade pip and install EasyBuild (one time only)
# pip install --upgrade pip
# pip install easybuild

# optional: show version
eb --version

If you start a new shell, re-export EASYBUILD_PREFIX/MODULEPATH and source the venv again.

Place this repo (the folder with the .eb files) anywhere, e.g.

~/scratch/easybuild/vista_easybuild/

We will point --robot to this directory so EasyBuild can find all recipes locally.

cd ~/scratch/easybuild/vista_easybuild

# Build with automatic dependency resolution from current folder
eb ParaView-ANARI-iw-6.0.1-foss-2024a.eb \
   --robot=$PWD \
   --rebuild \
   --job 8 \
   --skip-test  # see Perl note below

eb Visit-ANARI-mj-3.5.0-foss-2024a.eb \
   --robot=$PWD \
   --rebuild \
   --job 8 \
   --skip-test  # see Perl note below

The Perl and Perl-bundle-CPAN easyconfigs in this set fail their test phases on this platform. The builds themselves are fine, but the test targets exit non-zero. Use --skip-test to avoid stopping the full dependency graph.

Load modules like:

module use $EASYBUILD_PREFIX/modules/all
module avail
module load ParaView-ANARI-iw/6.0.1-foss-2024a
# or
module load Visit-ANARI-mj/3.5.0-foss-2024a

Use --robot=$PWD so that dependencies are picked from this folder first.

• These recipes are tuned for aarch64 nodes with NVIDIA GH200.
• CUDA 12.8 is provided as an easyconfig to ensure builds find a consistent toolkit.
• If the site has global modules you prefer, you may load the site's foss/2024a first and let EasyBuild reuse/align with it. Otherwise, the local tree is self-contained.

• --dry-run – show what would be built and where
• --job N – parallel build (per package)
• --robot-paths=$PWD:/extra/eb/roots – add more search roots
• --from-pr / --try-toolchain – advanced debugging
• --force – rebuild even if a module exists (use with care)

• Perl test failures → build with --skip-test (known on this platform).
• Missing modules after build → ensure module use $EASYBUILD_PREFIX/modules/all in your shell/profile.
• CMakeLists not found → some projects keep sources under src/; the .eb files already set correct sources/start_dir. Build via the provided recipes rather than calling CMake manually.
• Linking to CUDA/OSPRay/Embree → keep consistent toolchain (foss/2024a) across all dependencies; let --robot resolve from this repo.
