MemoryUB (UB Read/Write Bandwidth Rate)

MemoryUB.csv stores the collected MTE/Vector/Scalar UB read/write bandwidth rate data. For details, see the field description in the following table.

The unit GB/s indicates that 1 GB of data is transmitted per second.

aiv_time(us)

Execution time of each AI Vector Core compute unit after the task is allocated to the unit, in μs.

aiv_total_cycles

Total number of cycles executed on each AI Vector Core compute unit after the task is allocated to the unit.

aiv_ub_read_bw_vector(GB/s)

Bandwidth of data read from UB by Vector corresponding to the total cycles, in GB/s.
