# Python3 manifest example
#
# This manifest was prepared and tested on Ubuntu 16.04.
#
# Python must be run with the pal_loader:
#
# ./pal_loader python.manifest <script>

# The executable to load in Graphene. By default, PYTHONHOME points to the
# system installation. To run Python from a local installation, specify PYTHONHOME
# when running `make` in this directory.

# option (inline/none).

# Graphene general options

# Graphene creates stacks of 256KB by default. It is not enough for SciPy/NumPy
# packages, e.g., libopenblas dependency assumes more than 512KB-sized stacks.
sys.stack.size = 2M

# SGX general options

# Set the virtual memory size of the SGX enclave. For SGX v1, the enclave
# size must be specified during signing. If Python needs more virtual memory
# than the enclave size, Graphene will not be able to allocate it.
sgx.enclave_size = 1G

# Set the maximum number of enclave threads. For SGX v1, the number of enclave
# TCSes must be specified during signing, so the application cannot use more
# threads than the number of TCSes. Note that Graphene also creates an internal
# thread for handling inter-process communication (IPC), and potentially another
# thread for asynchronous events. Therefore, the actual number of threads that
# the application can create is (sgx.thread_num - 2).
