Does it show that my cluster runs perfectly?

Hi,:)
  yestoday ,I test this beowulf cluster by linpack and get some data.during 
the testing ,i change the N so that the linpack can lead to the BEST 
performance.for example,i have 2 nodes with PIII 933 (1 master node and 1 
slave node),2*1G=2G memory.so the N can be 10000(if i let N=12000 or 
N=15000,it will cause error :(  ).i am sure the net is beyond the request 
in this test.finally,the linpack output such result:
  T/V       N      NB  P  Q   Time    Gflops
  w11c2c4  10000   60  1  2   725.99  9.205e-1
  in the abstract,the cluster can reach 0.933*2=1.866Gflops( i am not sure 
whether it can be calculated in this way).it seems that the cluster works 
so
badly.do it?
  maybe you can teach me how to judge the performance of the cluster by 
observing these data.maybe there is a stardard to do so.but i dont know.:(
  thanks for your attention. ^_^
  Regards
