Meanwhile, with remarkable performance, it can process the data on disk or/and in memory, which is what makes Apache Spark powerful. In this regard, data shuffling, an extra difficult transformation operation leads to important challenges, because, data shuffling is the main component of complex ...
1 It primarily achieves this by caching data required for computation in the memory of the nodes in the cluster. In-memory cluster computation enables Spark to run iterative algorithms, as programs can checkpoint data and refer back to it without reloading it from disk; in addition, it ...
3 Spark Programming Interface To use Spark, developers write adriverprogram thatconnects to a cluster ofworkers, as shown in Figure 2.The driver defines one or more RDDs and invokes actions on them.Spark code on the driver also tracks theRDDs’ lineage. The workers are long-lived rocessest...
Given the low latencies attained with in-memory data, we wanted to let users run Spark interactively from the interpreter to query big datasets. We found the Spark interpreter to be useful in processing large traces obtained as part of our research and exploring datasets stored in HDFS. We als...

While Spark distributes computation across nodes in the form of partitions, within a partition, computation has historically been performed on CPU cores. However, the benefits of GPU acceleration in Spark are many. For one, fewer servers are required, reducing infrastructure cost. And, because quer...
