Dear colleagues, This months newsletter on IT @ Bioquant deals with the following very different topics: Printing @ BioQuant Cluster News: Integration of the Tesla Machines into the Bioquant Cluster Network OpenMPI on the Bioquant Cluster PBS Submit Hosts appl9 and appl10 Power glitch on Campus Software Printing @ BioQuant After some months since we introduced our "Poster Printing Service" we finally recommend the following procedure: Bring in your poster on a USB stick or similar. We will print it for you in time. This will save your time, some paper and a lot of ink plus our sanity. Or simply mail your poster to our usual support address support-it@bioquant.uni-heidelberg.de. We will make a test print in A4 and ask for your confirmation to print in poster size. This is from now on the only possible procedure. Integration of the Tesla Machines into the Bioquant Cluster Network The Tesla machines teslaL and teslaR are now integrated into the private network of the Bioquant Cluster. Thus they are now accessible over pbs with their internal names, teslaL-int and teslaR-int respectively. If you want to start an interactive session on one of those machines, use the following command on appl1: qsub -q cuda -I -lnodes=tesla{R|L}-int OpenMPI on the Bioquant Cluster OpenMPI, version 1.3.3, has been installed on the Cluster. The installation path is: /usr/local/openmpi-1.3.3 To run parallel MPI Jobs on the Cluster, you can proceed as usual and submit your job with the qsub command on appl1. OpenMPI reads the $PBS_NODEFILE and starts as many processes as the reserved processors. For nodes having the icc feature an additional installation of OpenMPI is available, which has been compiled with the Intel Compiler Suite and provides compiler wrappers for it. The installation path is: /usr/local/openmpi-1.3.3-intel_cc For more details on the cluster, check out our IT website at: http://www.bioquant.uni-heidelberg.de/about-us/organigram/it/it-services/compute-cluster.html PBS Submit Hosts appl9 and appl10 The Linux application servers appl9 and appl10 have been configured as submit hosts for the Bioquant cluster. All common commands are available on those machines, e.g. qsub for job submission and qstat for job checking. Note that the PBS Server is still on appl1, i.e. no server instance runs on appl9 and appl10 Power glitch on Campus After the power glitch on th campus some weeks ago, which shut down some of our machines because of an overvoltage seen at their power supplies, we started to secure our network and services even more: most of our services are now "more" redundant than before. This is true especially for the cluster and the license server. This time, we learned these things the tough way, as we could not foresee this behaviour of the mains supply of the University. But we were fully functional again after only a day. Software: Maple 13, Matlab 7.8 (R2009a), SAS 9.2 Maple is now available as version 13, Matlab as release R2009a, i.e. 7.8. SAS 9.1.3, SAS 9.2 für Windows XP/Vista (32-bit), EG 4.1 und EG 4.2 and JMP for Windows, Mac and Linux is now also available in a small number of licenses. Interested may contact me for further details. And as usual: our mail address for your problems is support-it@bioquant.uni-heidelberg.de.
