Testing the application of various checksum methods.
Brief Explanation:
This program written as an assignment for the "Fault Tolerant Computer
Systems" course, Fall 2000. We may use it to test the application of
"CheckSum" as an Information Redundancy method. Various data sources may be
selected including:
- Data of all files in the current drive of Hard Disk
- Random Numbers with Uniform distribution
- Random Numbers with Gaussian distribution
- Random Numbers with Rayleigh distribution
- Random Numbers with Poisson distribution
- Random Numbers with "ramp shaped" distribution
- Random Numbers with "exponential shaped" distribution
- Random Numbers with "logarithmic shaped" distribution
The program includes two independent histogram window, so we may also compare the result of various checksum generation methods. The histogram generation routine runs as an independent thread and selecting another histogram while program is busy with the computation would be available and we will see the results on the fly.
You may download the last available version as freeware from the download page.
