Chart Entries

Columns

Rank <-> Rank

Numbers of communicating ranks

Volume(MB)

Amount of data transferred in the communication (in megabytes)

Volume(%)

Percentage of amount of data transferred in the communication

Transfers

Number of messages in the communication

Rows

TOTAL

Total values for all columns

AVG

Average values for all columns. The values are calculated as follows: AVG = TOTAL / [(N*N + N)/2], where N is the number of ranks
