i means that since the scyld beowulf including linpack (but do not have 
HPL.dat), so if i do not download or edit a HPL.dat,can linpack including 
in the scyld beowulf benchmark the beowulf cluster correctly? if can 
not,why 
not the *scyld* include the HPL.dat or some relative documents ?
i am a newbie to beowulf and cluster ,i just have a impression on 
linpack,when
 i first run linpack in scyld beowulf, i even think that my cluster is so 
poor----for it's peak just reach 0.8 G (1 master node+1 slave node,each pc 
equips with pIII 933 and 1G ram).
  can u give me more advice?
