I was to able to wrestle free standing unlimited MATLAB license from Miss Laura K. Walsh who is MATLAB software licensing manager for CMU for all Auton desktops and computing nodes. In practical terms that means that I am the MATLAB license manager for Auton Lab with MathWorks account and our computers will need not to verify through CMU licensing server. Over next couple of days many of Linux desktop users (I have Windows copies too) will notice /usr/local/MATLAB directory on their computers. The directory contains the latest 2013a edition of MATLAB with all tool boxes licensed to CMU. To use the local copy of MATLAB you will have to use absolute path /usr/local/MATLAB/R2013a/bin/matlab to launch the application. Preferably you can edit search path export PATH=/usr/local/MATLAB/R2013a/bin/ or edit alias to your shell profile. For example my .kshrc (I always use Korn shell) reads alias matlab='/usr/local/MATLAB/R2013a/bin/matlab' Computing nodes which are currently deployed will be eventually switch to the new licensing model which means that you will not see any nasty surprises due to down time of CMU MATLAB licensing server. However at this point the highest priority is to deploy two new computing nodes 64 cores and 256 GB RAM each which will first have new MATLAB installation. I would also like to call at this point MATLAB users to switch from using a copy of MATLAB installed on our file server to using local copies of MATLAB for code writing, debugging, and testing before hitting computing nodes. That would help speed up our network connections. Please let me know if you need a copy of MATLAB and you are under Auton Lab software support.

He will be speaking "On the Computational and Statistical Interface and "Big Data" This is the abstract of his talk: On the Computational and Statistical Interface and "Big Data" The rapid growth in the size and scope of datasets in science and technology has created a need for novel foundational perspectives on data analysis that blend the statistical and computational sciences. That classical perspectives from these fields are not adequate to address emerging problems in "Big Data" is apparent from their sharply divergent nature at an elementary level in computer science, the growth of the number of data points is a source of "complexity" that must be tamed via algorithms or hardware, whereas in statistics, the growth of the number of data points is a source of "simplicity" in that inferences are generally stronger and asymptotic results can be invoked. Indeed, if data are a data analyst's principal resource, why should more data be burdensome in some sense? Shouldn't it be possible to exploit the increasing inferential strength of data at scale to keep computational complexity at bay? I present three research vignettes that pursue this theme, the first involving the deployment of resampling methods such as the bootstrap on parallel and distributed computing platforms, the second involving large-scale matrix completion, and the third introducing a methodology of "algorithmic weakening," whereby hierarchies of convex relaxations are used to control statistical risk as data accrue.

I apologize for the late notice. I was under impression that you have received the help desk message which might not be the case. I am not planning to take any servers down. Hopefully our PSUs will be able to keep them alive for 60 minutes. If you notice anything strange tomorrow morning please report. Most Kind Regards, Predrag -------- Original Message -------- Subject: REMINDER: Planned Power Outage in Wean Hall, Newell Simon Hall, Hamburg Hall, and Smith Hall - 10/18 Date: Thu, 17 Oct 2013 11:37:25 -0400 From: Help Desk To: Help Desk Date: Friday, October 18, 2013 Time: 5:00 AM Services Affected: Desktop machines in Hamburg Hall, Smith Hall, Newell Simon Hall, and Wean Hall and some computer clusters in the Wean Hall machine room. Details: Facilities Management Services continues planning electrical shutdowns necessary for balancing the power loads between circuits across main campus. The transfers are scheduled for Friday, October 18, mid semester break and no classes. Wean Hall 5:00-6:00 AM Newell Simon Hall 6:15-7:00 AM Hamburg and Smith Halls 7:00-7:30 AM It is recommended that you shut down any desktop machines in Hamburg, Smith, Newell Simon and Wean Halls prior to this outage as a precaution. At 5:00 AM Friday, October 18 the SCS machine room in Wean Hall will lose power for 60 minutes. All servers located there have UPS backup and should not be affected unless the power outage lasts longer than planned or if a UPS experiences a failure. SCS Computing Facilities staff will be present in the machine room to monitor the situation and react if necessary. Some SCS Compute Clusters contain compute nodes that are not on UPS power, so these nodes will power off. Cluster owners will be contacted separately. Servers located in the Gates-Hillman data center, where most of the core servers for SCS Computing Facilities services reside, will not be affected. There should be no interruption of SCS network connectivity, email services, AFS or printing. Please contact the SCS Help Desk at x8-4231 or send mail to help+ at cs.cmu.edu with any questions or concerns regarding this power outage.

Machine name is lov3 (l as in Lab, o as in Opteron in this case 64 cores and v as in 256 GB of RAM according to our internal documentation). You can ssh into lov3 via our SSH gateways lop1 and lop2 with your regular Auton Lab credentials. You home directories are mounted. Local HDD is very small and used only for administrative purpose. Lov3 doesn't run X server but you can use X-clients via ssh -y option. For the complete list of currently installed computational software with version numbers please refer to http://predrag.freeshell.org/software_installation.xls Few small remarks. Default system GCC on RedHat is 4.4 but I installed 4.7. Default system Python is 2.6 but you should be using installed 2.7.3 To call such Python please use python27 command or if you use ipython shell ipython27. When I say Python is installed that means all standard modules as well numpy, scipy, matplotlib etc (the most recent versions). When I say Perl is installed means that I installed most common Perl modules as well. To use matlab type in the shell matlab -nodesktop Please, please test and report problems. If the problems are not reported they are not likely to be fixed. I am still in the process of configuring monitoring systems. Finally I would like to take this opportunity to thank Dr. Dubrawki and Dr. Schneider as well as their Co-PIs whose grant money was used to purchase these two wonderful machines.
