例如，DB 2 LOAD可以在每个分区上同时运行，负载操作可以并行地分摊到多个服务器上。
For example, DB2 load could run simultaneously on each partition, splitting the load operation up in parallel across the servers.
最后两个影响性能的要素是备用服务器上的读操作和内部并行性。
The last two elements that affect performance are reading from secondary server and internal parallelism.
并行作业管理器层同样也是计算网格的组成部分，可以将较大的作业分解为较小的分区、并为跨集群执行的分区作业提供操作控制。
Parallel Job Manager tier, also part of Compute Grid, decomposes large jobs into smaller partitions and provides operational control over partitioned jobs executing across the cluster.
