Title: Bodo approach: how to build a compiler for optimizing and parallelizing Python computation
Bodo is a parallel compute platform that combines Python simplicity and HPC performance/scalability for large-scale data analytics/AI/ML. Bodo uses a new auto-parallelizing just-in-time (JIT) compiler approach that compiles code to optimized parallel binaries with MPI, whereas other distributed data processing frameworks use a high-overhead driver-executor runtime library. Hence, Bodo is usually more scalable and orders of magnitude faster than alternatives such as Spark and Dask. Find out more at https://bodo.ai.
In this talk, we discuss how Bodo’s automatic parallelization and optimization machinery works internally, such as the way high-level Python APIs are optimized as deeply embedded DSLs. We will use interactive Jupyter notebooks to go through example codes and explain various compiler stages from Python bytecode to optimized high-level IR and LLVM IR.
