Memory Utilization

Some applications read all data into RAM by default:

  • R
  • MATLAB
  • Excel
  • Stata

In each of these cases, there are some tools or methods to help reduce consumption.

CPU Utilization

Parallel Processing

  • "Divide and Conquer"
    • Break down tasks into many small ones
    • Maximize CPU core utilization
  • MapReduce
    • Open source framework for parallel processing
  • GNU Parallel
    • Open source tool for managing parallel tasks
  • Examples:
    • Climate data
