For the comparison, the software measures your network connection speed to the World Community Grid servers.
How are points calculated?
Points are calculated and awarded each time a work unit is completed and a result is successfully returned to World Community Grid Servers. Points are totaled across all machines aggregated under a specific World Community Grid Member.
Points are based upon the strength of your machine(s), measured against World Community Grid Comparison Device. First, the strength of your participating machine(s) is calculated by measuring the following parameters of your machine against World Community Grid Comparison Device:
CPU Power
: The software periodically runs diagnostic tests to establish the processing power of your hardware configuration. These values are averaged and then divided by the CPU-Power value of World Community Grid Comparison Device. The averaged value is then multiplied by the run time used to complete the work unit and return the results to World Community Grid Servers.
Random Access Memory (RAM)
: The software recognizes the amount of RAM in your hardware configuration. Each time the software starts, it detects any changes to the amount of installed RAM. This value is divided by the RAM value of World Community Grid Comparison Device. The result of this calculation is then multiplied by the run time used to complete the work unit and return the results to World Community Grid Servers.
Hard Disk Storage
: On your preferences page, you set the megabytes of hard disk space allocated and available to World Community Grid projects. The lesser of the amount of hard drive space allocated and the amount of total space available on your hard drive partition, is divided by the Hard Disk Storage value of World Community Grid Comparison Device. The result of this calculation is then multiplied by the run time used to complete the work unit and return the results to World Community Grid Servers.
Effective Upstream Throughput
: The software runs a diagnostic test on a regular basis that measures the upstream throughput of your hardware configuration, when communicating with World Community Grid Servers. These values are averaged, and the result is divided by the Effective Upstream Throughput value of World Community Grid Comparison Device. The result of this calculation is then multiplied by the run time used to complete the work unit and return the results to World Community Grid Servers.
The final values for all four parameters are weighted, totaled, and factored to generate a whole number of points greater than or equal to 1 for each result returned. While any individual parameter can overachieve the corresponding parameter for World Community Grid Comparison Device by any level, no work unit completed by any machine will earn more than twice the total number of points World Community Grid Comparison Device would earn for that same work unit. Note: The slightest variance in any of the five parameters coupled with the inherent differences across multiple applications and work units within one project will result in different point values being assigned per work unit completion.
