5903 Intro Scientific Prog:
Timing Matrix Access: Specification

1. Find out how large a square matrix of doubles you can create on your computer.  Explain your process and reasoning.  Is this consistent with the computers specs?
2. Create a matrix of this maximum dimension.
3. Time how long it takes to access a matrix entry in a variety of patterns
• Across rows and then down to the next row.
• The reverse of this.
• Down columns and then across to the next row.
• The reverse of this.
• In a random pattern.  Make sure you subtract out the time to compute the randomness.
4. Comment on the timing results.  Explain it if you can.
