# Tachyon Bazel configuration file.
# This file tries to group and simply build option for Tachyon
#
# ----CONFIG OPTIONS----
#
# Other build options:
#     dbg:       Build with debug info
#
# Hardware support options:
#     cuda: Build with NVIDIA GPU support (cuda).
#     rocm: Build with AMD GPU support (rocm).
#     numa: Enable numa using hwloc.
#
# Default build options. These are applied first and unconditionally.

# For projects which use Tachyon as part of a Bazel build process, putting
# nothing in a bazelrc will default to a monolithic build. The following line
# opts in to modular op registration support by default.
