HPL 2.3 from netlib compiled against OpenBLAS with a minimal single-process MPI stub — no MPI package required in the ISO. Matrix size is auto-sized to 80% of total RAM at runtime. Build: - VERSIONS: HPL_VERSION=2.3, HPL_SHA256=32c5c17d… - build-hpl.sh: downloads HPL + OpenBLAS from Debian 12 repo, compiles xhpl with a self-contained mpi_stub.c - build.sh: step 80-hpl, injects xhpl + libopenblas into overlay Runtime: - bee-hpl: generates HPL.dat (N auto from /proc/meminfo, NB=256, P=1 Q=1), runs xhpl, prints standard WR... Gflops output - platform/hpl.go: RunHPL(), parses WR line → GFlops + PASSED/FAILED - tasks.go: target "hpl" - pages.go: LINPACK (HPL) card in validate/stress grid (stress-only) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
ISO Build
bee ISO is built inside a Debian 12 builder container via iso/builder/build-in-container.sh.
Requirements
- Docker Desktop or another Docker-compatible container runtime
- Privileged containers enabled
- Enough free disk space for builder cache, Debian live-build artifacts, NVIDIA driver cache, and CUDA userspace packages
Build On macOS
From the repository root:
sh iso/builder/build-in-container.sh
The script defaults to linux/amd64 builder containers, so it works on:
- Intel Mac
- Apple Silicon (
M1/M2/M3/M4) via Docker Desktop's Linux VM
You do not need to pass --platform manually for normal ISO builds.
Useful Options
Build with explicit SSH keys baked into the ISO:
sh iso/builder/build-in-container.sh --authorized-keys ~/.ssh/id_ed25519.pub
Rebuild the builder image:
sh iso/builder/build-in-container.sh --rebuild-image
Use a custom cache directory:
sh iso/builder/build-in-container.sh --cache-dir /path/to/cache
Notes
- The builder image is automatically rebuilt if the local tag exists for the wrong architecture.
- The live ISO boots with Debian
live-boottoram, so the read-only medium is copied into RAM during boot and the runtime no longer depends on the original USB/BMC virtual media staying present. - Target systems need enough RAM for the full compressed live medium plus normal runtime overhead, or boot may fail before reaching the TUI.
- The NVIDIA variant installs DCGM 4 packages matched to the CUDA user-mode driver major version. For driver branch
590/ CUDA13.x, the package family isdatacenter-gpu-manager-4-cuda13rather than legacydatacenter-gpu-manager. - Override the container platform only if you know why:
BEE_BUILDER_PLATFORM=linux/amd64 sh iso/builder/build-in-container.sh
- The shipped ISO is still
amd64. - Output ISO artifacts are written under
dist/.
