Why do both AVX2 intrinsics use the same instruction

## Summary In AVX2 instruction sets, intrinsics `_mm256_bslli_epi128` and `_mm256_slli_si256` both compile to the identical `vpslldq` instruction despite their differing names. This occurs because Intel maintains **backward-compatibility aliases** alongside updated naming conventions for clarity. No functional difference exists between these intrinsics; the duplication is purely syntactic. ## Root Cause * **Legacy naming conventions**: Earlier SSE/AVX … Read more

How to make spark reuse python workers where we have done some costly init set up?

Apache Spark Worker Reuse Pitfall:ㄨ Optimizing Costly UDF Initialization Summary A PySpark deployment using Pandas UDFs with expensive initialization (e.g., ML model loading) failed to reuse Python worker processes, causing repeated costly setups. This occurred despite configuring spark.sql.execution.pyspark.udf.idleTimeoutSeconds solely – because Python worker factories forcibly terminate workers after a separate hard-coded 60-second timeout, even if … Read more
