Deepwalk fails when scale=30

[kurapika0]

I run into this problem when I try to deepwalk a scale=30 graph

The script is like

KK_BIN="/path/to/KnightKing/build/bin"

SCALE=30
VERTEX_COUNT=$((2 ** SCALE))
WALKERS=$((V / 1000000)); [[ "$W" -lt 1 ]] && W=1

# graph500.git
mpiexec -n "$NP" ./graph500_reference_bfs "$SCALE"
# ---------- bin → txt ----------
python3 "$PY_CONVERTER" "$BIN_FILE" "$TXT_FILE"
# ---------- txt → KnightKing .data ----------
"$KK_BIN/gconverter" -i "$TXT_FILE" -o "$DATA_FILE" -s unweighted
# ---------- DeepWalk ----------
"$KK_BIN/deepwalk" -g "$DATA_FILE" -v "$VERTEX_COUNT" -w "$WALKERS" -s unweighted -r 0.1 -l 10

The script run successfully for SCALE=16 but fails for SCALE=30.
Is this because KnightKing does not support such a large scale or there are some configuration problems on my side?
