first,thanks for your help.:)
now ,when i try to execute the larger size benchmark.i got some error.:(
which will cause the following error:
1.found a dead connection while look for messages 7
2.beostat_reg:beostat_lib.c:100 connection failed connection refused
3.rm_1_12_11065:p4_error:net_recv read:probable Eof on socket 1
...
if i calculate small matrix,such as 5000 on 16 nodes.it can work correctly.
but when i set the N=40000(16G Memory) ,and let it work on 16 nodes.i will 
receive some error message and then i can not continue to compute.:(i am a 
beginner,i need your help.:)
following is the main parameter:
HPL.out      output file name (if any)
