The problem appears to be sequential so how would SIMD help? Also what advances in squatting algorithms have there been specifically? None of the links you have provided appear relevant

The numbers involved are quite large. They don't fit into a single computer word.
The problem is designed so that iterations have to be sequential, but a single iteration can use parallelism.
SIMD instructions[2] lowered the amount of cpu cycles needed per operation.
Novel algorithms[3] lowered the amount of operations needed per iteration.
