WebApr 10, 2024 · I thought this was a bit strange, because the dataset as a whole used only about 2 Gb of memory, and 740 Gb seems far too large. To debug this, I decided to partition the data and observe how the size of the vector required changes based on the number of obs (rows) in the dataset. First, I made a partition of the first 500k rows of the … WebIn this model, memory allocation has two partitions: low memory and high memory. The operating system is in low memory. User processes occupy high memory. Memory can be separated into fixed-size divisions made of contiguous physical address space, and each partition contains only one process.
