  • Using @stewartsmith's EatMyData wrapper to speed up a git svn clone, very useful! 🙂 #
  • So Adaptive Computing are moving from NetSuite to Salesforce for their support system. Wonder if it'll be any better.. #
  • To be honest I wish they'd never stopped using RT, that worked so well for us. #
  • SELinux changes to Kerberos in RHEL6/CentOS6 cause slow downs due to huge regexps http://t.co/8fDM8KCG v/ @jamesdotcuff #
  • So the #Linux kernel for @Intel's Knights Corner is the obsolete, non-LTS 2.6.34.. 🙁 http://t.co/Fiozg4CL #hpc #
  • Why on earth would Cisco Nexus 7018's drop the initial SYN to a host they've not talked to for a while? /cc @incorrect #
  • "64K of 64K processors in use by local jobs" – w00t! #VLSCI BlueGene/Q is now in acceptance testing with real #HPC code #
  • #LVSCI BlueGene/Q clocked a Linpack (xhpl) score of 695TF, that's 82.7% efficiency given peak of 840TF #hpc #top500 #
  • #VLSCI BlueGene/Q about double combined performance of all 4 Australian supercomputer sites on last #Top500 #HPC list! #
  • #VLSCI BlueGene/Q clocked a Linpack (xhpl) score of 695TF, that's 82.7% efficiency given peak of 840TF #hpc #top500 #
  • If Joe Hockey thinks 4G is better than #NBN he must think 35Mb/s > 1000Mb/s. Not a good sign for a wannabe treasurer. #
  • Interesting kickstarter project to make #git annexe into an open-source automated Dropbox like tool. http://t.co/6G0o4XfU #
  • Hat tip to @penguin_brian for pointer to that kickstarter project. #
  • Gina Rinehart takes A.J. Liebling's "Freedom of the press is limited to those who own one" to heart, wants to own them all #
  • #ff #followFriday @TonyNicklinson #
  • #VLSCI BlueGene/Q completed 3 days of reliability acceptance tests at full load with not a single hardware. 🙂 #hpc #
  • Oops I meant no hardware *failures* on our BG/Q testing, not no hardware at all. Slurm BG/Q simulator isn't that good. 🙂 #
  • First ever scored round at archery training this morning. Scored 199 with 30 arrows @ 20m with recurve. Pretty happy. #
  • Impressed by @ibmhpc BG/Q techs: arrived Monday 28th to assemble+cable, had Linpack running on full system by Friday. #hpc #

  • Lyrics are from "Ballad" written by Justin Sullivan in 1986 but apply perfectly to what passes for debate in #auspol #

  • Being part of team building + running (hopefully) the most powerful supercomputer in southern hemisphere is a great honour. #
