Tips and tricks from the Beowulf mailing list
========
* Jon Tegner [m1] is looking for  a distributed file system and asking
  if AFS good be the choice.  Sean Dilda [m2] explained why AFS is not
  suited for cluster.  Thierry Mallard [m3] pointed him to GFS [1] and
  Robert Ross [m4] when NFS or PVFS could be needed.

* Raul  A.  Gonzalez   Olimon [m1]  experienced  problem  with channel
  bonding on  RTL8139  NIC. Except  W  Bauske   [m2]  who reported  no
  problem,   all    other  beowulfers  do    not  recommend  this  NIC

  Joel Jaeggli [m2] wrote this chipset doesn't do SMP.  Mark Hahn [m3]
  posted a link [1] to few similar streams benchmark.
