What Does Mean 64bit?
- 64bit addressing
- The program has 64bit address space for memory access
- So it can access more than 4GB of memory per process
- This requires OS and H/W which can manipulate 64bit memory address space
- 64bit precision
- The variables are 64bit and go through the computation with 64bit precision
- This requires more memory than 32bit precision
- This may require more disk space for input/output data
- This requires more computational power than 32bit precision
