python bindings for c++ arena allocator (xo-arena)
Exposes xo-arena's configuration types to python:
ArenaConfig, AllocHeaderConfig, and the AllocHeader word the latter
describes.
Getting Started
build + install dependencies
build + install
$ cd xo-pyarena
$ mkdir build
$ cd build
$ INSTALL_PREFIX=/usr/local # or wherever you prefer, e.g. ~/local
$ cmake \
-DCMAKE_MODULE_PATH=${INSTALL_PREFIX}/share/cmake \
-DCMAKE_PREFIX_PATH=${INSTALL_PREFIX} \
-DCMAKE_INSTALL_PREFIX=${INSTALL_PREFIX} ..
$ make
$ make install
Examples
From an umbrella build, xo-python puts every xo pybind module on PYTHONPATH:
$ .build/xo-python
>>> import xo.arena as mm
>>> mm.ArenaConfig(name="scratch", size=64*1024)
<ArenaConfig name='scratch' size=65536 hugepage_z=2097152 store_header_flag=False debug_flag=False>
>>> mm.AllocHeaderConfig()
<AllocHeaderConfig tseq_bits=24 age_bits=8 size_bits=32 guard_z=0>
See xo-pyfacet/examples/flywheel_pretty.py for these configs in use.
