# The DPU application reads blocks of data from MRAM to WRAM via mram_read
# and copies blocks of data from WRAM to MRAM via mram_write.
# Each transfer handles BLOCK_SIZE (BL<<2) bytes via DMA.
# Each DPU reports its total runtime, i.e., the number of cycles accumulated
# over all mram_read or mram_write calls.
# Total data size is 8192 uint64 elements, so 65536 B (64 KiB)
# Overall throughput is 65536 B / dpu_seconds
# Per-DPU throughput is 65536 B / (dpu_seconds * nr_tasklets)
# Latency per mram_* call is dpu_seconds / dpu_count
