# Args: -m m -n n -o M_ -p N_
#
# Input: (M_ * m) × (N_ * n) matrix
# Output: (N_* n) × (M_ * m) matrix
# Step 1: transpose (M_ * m) × N_ matrix that consists of tiles of size n
#   CPU version: explicit
#   DPU version: implicit (M_ * m write operations of #DPUs * n elements to DPUs)
# Step 2: transpose m × n matrix; this happens N_ * M_ times.
#   DPU version: Each tasklet transposes a single m × n matrix / tile.
#   (16 × 8 tile takes up 1 KiB WRAM)
# Step 3: Transpose M_ × n matrix that consists of tiles of size m.
#
# Note for DPU version: if M_ > #DPUs, steps 1 through 3 are repeated.
# Number of repetitions == ceil(M_ / #DPUS)
# For Hetsim benchmarks, we set M_ == #DPUs to simplify the task graph (no repetitions that depend on the number of available DPUs).
# Just in case, there is also a configuration with M_ == 2048 independent of #DPUs
#
# input size: uint64(DPU)/double(CPU) * M_ * m * N_ * n
# output size: uint64(DPU)/double(CPU) * M_ * m * N_ * n -- on DPU only; CPU version operates in-place
# Upstream DPU version uses int64_t, -p 2048 -o 12288 -x 1 [implicit -m 16 -n 8]
# Upstream CPU version uses double,  -p 2556 -o 4096 -m 16 -n 8 and fails with -o 12288 (allocation error)
#
# -p         2048 -o 2048 -m 16 -n 8 -> matrix size: 4 GiB
# -p [64 .. 2304] -o 2048 -m 16 -n 8 -> matrix size: 128 MiB .. 4.5 GiB
