Twitter Weekly Updates for 2012-06-24

Posted on June 24, 2012 by Chris Samuel
  • Lots of people complaining about cost cutting @ The Age. I wonder how many buy it? If you don't then you're the cause.. #
  • OK, Firefox Auto-Refresh extension installed, @top500supercomp June 2012 list page selected, auto-refresh 1 minute. #hpc #
  • Ooh, the @top500supercomp website is currently being updated! 🙂 #top500 #isc2012 #
  • New #Top500 is out, #VLSCI is #31 with Avoca, our BG/Q! Sequoia at LLNL is #1 with 16PF #hpc #isc2012 #
  • Actually #VLSCI is really tied for the #29 place in #top500 with EDF and IDRIS/GENCI in France.. 🙂 #hpc #
  • Australia – #31 (VLSCI), #139 (NCI/ANU), #156 (CSIRO), #248 iVEC), #301 (graphics company), #454 (Defence) on #top500 #hpc #
  • Bug in #Linux RAID/MD code can lose config for assembling arrays on reboot http://t.co/F0tC0ybp via @lwnnet #
  • Microsoft launched tablets, ARM will have secure boot but x86 one should allow secure boot to be disabled. #Linux anyone? #
  • Wow, #earthquake in #Melbourne #
  • So that #melbquake beats my first experience of an earthquake in Tokyo in 2000.. #
  • Sigh, the Geoscience Australia earthquake site is already down.. 🙁 #
  • USGS puts epicenter of #melbquake between Trafalgar and Narracan near Moe in Gippsland. #earthquake #
  • Could @774melbourne + @abc_investigate look at why Geoscience Australia's site failed making people to use USGS? #melbquake #
  • In other earthshattering news (sorry), it's just 3C outside at the moment.. almost getting cold! #
  • ALP (and I presume Liberal/National coalition given it was their idea) are committed to unconstitutional school chaplains #
  • Interesting times, @fusionio have now picked up 2 key #btrfs developers, Chris from Oracle and @josefbacik from Red Hat. #
  • Just over 1/3rd way through Homo Britannicus by Chris Stringer, learned 2 new terms already: "vole clock" and "alder carr" #
  • Analysis of flint tool reworking by early Neanderthals in Channel Islands shows ratio of right to left handers same as now #
  • Just under 47 seconds to compile Perl 5.16.0 with make -j on our 32 core Power7 box (BG/Q service node). 🙂 #
  • Pulling my hair out – why does a RHEL6 #Linux NFSv4 mount not permit suid binaries to run on the client? (errno=-EACCES) #
  • User got free 30%+ speed boost running Trinity when I asked them to move from HSM filesystem to scratch filesystem 🙂 #hpc #
  • Journalists covering #top500 IBM BlueGene/Q does *NOT* run #Linux it runs IBM Compute Node Kernel (CNK). #hpc #
  • Only the BlueGene/Q IO nodes and support infrastructure (service nodes and front end nodes) run #RHEL6 #Linux. #hpc #
  • Don't get me wrong, I'm a big fan of Linux, but I prefer reporting of it (on the #top500 to be accurate. #
  • Just because the #Top500 website says IBM BlueGene/Q runs #Linux doesn't make it true.. #hpc #
  • Don't get me wrong, I'm a big fan of Linux, but I prefer reporting of it (on the #top500 and elsewhere) to be accurate. #
  • Belgrave Lantern Parade http://t.co/wGTsTt3s #
  • I liked a @YouTube video http://t.co/DUnMqASL UNDER MILK WOOD. #
  • Volunteers needed for annual lyrebird survey in Sherbooke Forest http://t.co/DP0GcOlv #
  • Gluten free dairy free lemon biscuits and ginger biscuits! 🙂 http://t.co/TuIAWgqp #
  • Italianette Maroondah Reflections – Maroondah Dam, Healesville http://t.co/1oQmcaOy #
  • Walk Into The Light – Maroondah Dam, Healesville http://t.co/bEBI6R7u #
  • Lyrebirds prove they're masters of mimicry http://t.co/kaeBes4o #abcmobile #

  • 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 #

  • Dear Australia, if your Eisteddfod isn't in Welsh then you're doing it wrong. Diolch yn fawr. #
  • Good blog from @sijoe about the mismatch between #storage performance expectations and reality http://t.co/OeBtBwjq #hpc #
  • Nice to see @googledownunder doing a tribute to Ruby Payne-Scott, radio astronomer, especially after the #SKA news. #
  • FPGA crypto HW backdoor discovered http://t.co/8AOcuUjc – FPGA with matching description http://t.co/Ffs0PQGm #security #
  • Looks like Cambridge people who discovered the backdoor had targeted the same chip in side-channel attacks in prev. papers #
  • Info on #VLSCI IBM #BlueGene Q supercomputer "Avoca" including obligatory install timelapse 🙂 http://t.co/rn1gPzwa #hpc #
  • Congrats @terryandrob! MT @ramtopsgrum
    BBC: Sir Terry Pratchett wins Wodehouse comic fiction award http://t.co/JWTTBjBn #
  • This #btrfs patch looks like it might be useful, especially for people using dpkg.. http://t.co/rY8ZkaSB #
  • "Not foolish and brave, these leaders of ours, but stupid and petty and unworthy of power" – @officialnma, apt for #auspol #
  • Lyrics are from "Ballad" written by Justin Sullivan in 1986 but apply perfectly to what passes for debate in #auspol #
  • TIGHAR has made real progress in gathering evidence for Earhart castaway theory. #Archaeology relevant for recent history. #
  • Being part of team building + running (hopefully) the most powerful supercomputer in southern hemisphere is a great honour. #
  • Started unfollowing people retweeting #govhack stuff, too noisy. Hopefully will remember to follow once it's over! #
  • Tomorrow, Sunday 3rd June, is the 20th anniversary of Eddie Mabo's historic indigenous land rights win in the High Court. #
  • Eddie Mabo et. al overturned the doctrine of Terra Nullius, that Australia belonged to nobody before Europeans arrived. #
  • It is shameful that it took so long to overturn such a painfully obvious false legal pretense. #
  • I liked a @YouTube video http://t.co/p4nXNKzT Professor Elemental – I'm British #
  • .@mjg59 updated blog on #Linux + UEFI secure boot to clarify payments go to Verisign not Microsoft https://t.co/NSSuMd7F #
