Spark
Spark is a fast and general cluster computing system for Big Data. It provides high-level APIs in Scala, Java, Python, and R, and an optimized engine that supports general computation graphs for data analysis. It also supports a rich set of higher-level tools including Spark SQL for SQL and DataFrames, MLlib for machine learning, GraphX for graph processing, and Spark Streaming for stream processing.
asySpark
AsySpark is an component of spark, this component can make machine learning work more efficient with a asynchronous computing model.such as asynchronous stochastic gradient descent.
