运行MPIrun的时候，步数增大之后会出现错误

运行MPIrun的时候，步数增大之后会出现错误，猜测可能是因为步数过多造成的死锁，应该如何修正呢。

问题相关代码，请勿粘贴截图 comm = MPI.COMM_WORLD

rank = comm.Get_rank()
nprocs = comm.Get_size()
nsteps = 1600000
if rank == 0:
ave, res = divmod(nsteps, nprocs)
counts = [ave + 1 if p < res else ave for p in range(nprocs)]
starts = [sum(counts[:p]) for p in range(nprocs)]
ends = [sum(counts[:p+1]) for p in range(nprocs)]
data = [(starts[p], ends[p]) for p in range(nprocs)]
else:
data = None

data = comm.scatter(data, root=0)
print(data)

运行结果及报错内容 Traceback (most recent call last):

File "interband_ImEps_tensor_MPI.py", line 106, in
x_MPI = comm.gather(x_MPI, root=0)
File "mpi4py/MPI/Comm.pyx", line 1262, in mpi4py.MPI.Comm.gather

File "mpi4py/MPI/msgpickle.pxi", line 139, in mpi4py.MPI.Pickle.alloc
SystemError: Negative size passed to PyBytes_FromStringAndSize

可能是因为步数太大了，没办法就算
