MPI_BCAST : Message truncated錯誤
矩陣A(n*n)在n=4000時，一個cpu也能正常運算，但是當cpu個數增加的時候，能夠實現正常運算的n的值卻很小如下：np表示cpu個數
n=200 run np=4 ok！
n=500 run np=4 failure 錯誤提示如下：
1 - MPI_BCAST : Message truncated
Aborting program !

p1_28511: p4_error: : 14

這是什麼錯誤，該如何解決呢？集群環境：
compiler：intel fortran 9.0
os：RedHat Enterprise Linux AS4.0
cpu：Nocona 3.0G
MPICH1.2.7
