main data memory

基本解释

According to the features of main memory data, the data organizing mode and index structure Ttree are introduced.
根据内存数据的特点，介绍了其数据组织方式和索引结构T树。
After each data processing step, you set up both a PUT to transfer the data to main memory and a GET to get the next batch of data.
在每个数据处理步骤之后，设置一个 PUT（将数据传输到主内存）和一个 GET（获得下一组数据）。
Instead of having multiple directly accessible arguments, you get a pointer into main memory and the SPE has to issue DMA requests to get the pointed-to data from main memory.
它没有使用多个可直接访问的参数，而是使用一个指向主存的指针，SPE 需要发出 DMA 请求来从主存中获取指针所指向的数据。
