Comparison cpu usage for dEdx calibration jobs using rcas and xeon-phi-dev

Comparison cpu usage of  dE/dx calibartion jobs using rcf rcas node with gpfs disks (1) and
HLT cluster xeon-phi-dev using sshfs mounted disks (2) :

  • cpu usage 31.0652/25.1238 => 1.24 => xeon-phi-dev (Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz)
    24% slower than rcas (Intel(R) Xeon(R) CPU  X5660  @ 2.80GHz)
  • no diffrence in IO percentage between rcas (8.5%) and xeon-phi-dev (8.5%). No effect for sshfs mounting disks (?)
