Executing Python code on bsg_replicant

[Amit Hiremath]

I was going through this file: https://github.com/bespoke-silicon-group/bsg_replicant/blob/e952023cc498c54a26a9c828ae1c3843b133cc68/examples/python/test_loader/main.c I don't see any path, or binary where python code is executed on bsg_manycore/bsg_replicany hardware. I think when one types make regression, it starts executing on host machine (x86_x64)?  Perhaps I am misunderstanding something?

Hi,

The example code linked uses the python c++ bindings to call into a python interpreter. It was written for Amazon F1 over 5 years ago and is not maintained. There's a chance you could get it working for ARM / Zynq. There's a very slim chance you could get a micropython interpreter running on BlackParrot but my understanding is that porting is non-trivial

bsg_replicant in general uses a C++ runtime very similar to CUDA APIs i.e. copy data from host to device, execute, copy data from device to host. An example of a generic loader for a "single program, multiple data" RV32 program is here: https://github.com/bespoke-silicon-group/bsg_replicant/blob/main/examples/spmd/loader.c. This is what we use to bootstrap the ZynqParrot emulator for HammerBlade

Best,

-Dan

Thanks Dan.  I know  bsg_replicant in general uses a C++ runtime API calls which are similar to CUDA. But my question was can we execute Python codes in RISCV core which are inside bsg_replicant, something like one could generate  main.riscv for python code and call this binary using bsg_replicant API for example:  https://github.com/bespoke-silicon-group/bsg_replicant/blob/main/examples/spmd/loader.c   ?
