+# BL: use 2^(BL) B blocks for MRAM <-> WRAM transfers on PIM module
+# T: data type
+# -w: number of un-timed warmup iterations
+# -e: number of timed iterations
+# -i: input size (number of elements, not number of bytes!)
+# Each DPU uses three buffers, each of which holds $i * sizeof($dt) bytes.
+# With a total MRAM capacity of 64M, this gives us ~21M per buffer, or 16M when rounding down to the next power of two.
+# With a maximum data type width of 8B (uint64_t, double), this limits the number of elements per DPU to 2097152.
