Table 1 lists the hardware requirements.

**Table 1** Hardware requirements
Item	Description
Processor	Kunpeng 920 5220
Memory size	384 GB (12 x 32 GB)
Memory frequency	2666 MHz
Network	10GE for the service network and GE for the management network
Drive	System drive: 1 x RAID 0 (1 x 1.2 TB SAS HDD) Data drive: 12 x RAID 0 (1 x 4 TB SATA HDD)
RAID controller card	LSI SAS3508

Table 2 lists the OS and software requirements.

The machine learning algorithm library supports Spark 2.3.2, Spark 2.4.5, and Spark 2.4.6, and provides the same APIs as the native algorithm library.
The algorithm library is compatible with Spark 3.1.1, but limited to the following algorithms: ALS, LDA, KNN, PrefixSpan, DBSCAN, Word2Vec, Decision Tree, DTB, Random Forest, and GBDT.
Spark 2.4.5 and Spark 2.4.6 use the JAR package of Spark 2.4.6.
It can also be adapted to 2.X and 3.X.
