backend="cpu" selects the CPU build. On a Mac the loader otherwise looks for a Metal build, which
this family does not ship. trust_remote_code names the repositories you allow; Hugging Face's
trusted publishers load without it.
Plain Python in, plain Python out. Lists, tuples, buffers and tensors are accepted wherever the
contract expects a list; structured results are dictionaries. Some functions take a list and the
number of elements to use from it, which may not exceed the list's length; multi-dimensional data is
passed flattened, row-major, with its dimensions. Functions that update an argument do so in place,
as help() says. Every call is checked against the published contract before it reaches native
code. An invalid call raises KernelError with a stable code, never a crash. Engine kernels
report shape and finiteness problems as a status; the wrapper raises KernelError named after it.
Any function can also be called by name, with args as a list or a dict of parameter names:
kernel.execute("data.dataframe", "df_from_columns", [...])

kernel.CONTRACT holds every signature, including the length rules for list arguments;
help(kernel.actuarial) documents each function.
Not included
column_rank.run_column_rank— takes a full JSON request string; reached through the column-ranking session, not a plain in-process call.combinatorial.tsp_greedy— reads its distance argument as a square matrix; a non-square nested list is not expressible as a length rule.contest_strategy.option_board— requires its per-entrant arrays to share one length; a mismatch is not expressible as a length rule.dependency.dependency_depth— walks an adjacency list that must be acyclic and in range; not expressible as a length rule.dimensionality.power_iteration— reads its matrix argument as square; a non-square nested list is not expressible as a length rule.
Requirements
- Apple silicon: macOS 15 or later for the CPU build.
- Linux arm64 and x86-64, glibc 2.35 or later.
kernels0.17 or later and PyTorch 2.5 to 2.14. PyTorch has to be installed: the loader picks the build for your PyTorch version. The kernel itself never imports it.
Windows is not supported.
Notes
Calls into one kernel instance run one at a time; use processes for parallelism. Runtime state
does not survive fork(); start worker processes with spawn.
License
Algenta Community License 1.1 (LICENSE). Free for personal, research and open-source use, and
for internal use at organizations with fewer than 50 employees and under $5M in annual revenue.
Beyond that, a commercial license is required: https://algenta.ai/pricing.
Enforced in the compiled library, not just in this text: one concurrent native worker per device (ABI §9). A second process, family or thread waits its turn rather than running in parallel. That is the Community licence's worker floor made real; parallel execution comes with a commercial license.
Support
Generally Available on the platforms listed under Requirements. Within v1, functions are only added;
removals or signature changes ship as v2. Platforms, accelerators and PyTorch releases not listed are not
supported. Documentation: https://docs.algenta.ai (the kernels guide:
