human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "moving processing to data on the influence of processing in memory on data management"):
  Abstract: Near-Data Processing refers to an architectural hardware and software paradigm, based on the co-location of storage and compute units. Ideally, it will allow to execute application-defined data- or compute-intensive operations in-situ, i.e. within (or close to) the physical data storage. Thus, Near-Data Processing seeks to minimize expensive data movement, improving performance, scalability, and resource-efficiency. Processing-in-Memory is a sub-class of Near-Data processing that targets data processing directly within memory (DRAM) chips. The effective use of Near-Data Processing mandates new architectures, algorithms, interfaces, and development toolchains.

Includes members:
  Member "enabling the adoption of processing in memory challenges mechanisms future research directions":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "machine learning systems for highly distributed and rapidly growing data")
  Member "architectural techniques for improving nand flash memory reliability":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "processing data where it makes sense enabling in memory computation")
  Member "hitting the memory wall implications of the obvious":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "flexible communication avoiding matrix multiplication on fpga with high level synthesis")
