%TOC{title="Content"}% ---+ Overview PALMA (Paralleles Linux-System für Münsteraner Anwender) is a cluster consisting of 3528 CPU cores. They are distributed as follows: * 36 nodes with 2 quadcore Intel Nehalem processors each, totally 8 cores per node * 254 nodes with 2 hexacore Intel Westmere processors, totally 12 cores per node * 4 SMP (shared memory) nodes with 32 cores each * 2 SMP (shared memory) nodes with 40 cores each The configuration in detail: Compute Nodes: * 2,6 GHz, 4 respectively 6 cores * 2 GB (Westmere) respectively 3 (Nehalem) respectively 4 GB (Westmere) main memory per core SMP-System: * 32 cores with 2 GHz * 256 GB RAM * Intel Xeon E4850, 2 GHz, 4x10 Cores * 512 GB RAM * Intel Xeon E4850, 2 GHz, 4x10 Cores * 256 GB RAM Filesystem: * 3 TB /home partition * 180 TB /scratch partition QDR Infiniband is serving as a fast interconnect. ---+++ [[palma:memory][Detailed list of all nodes with amount of memory]] ---+ Access to the system You have to fulfill two requirements to submit jobs on Palma: * You have to be a member of the group u0clustr ([[http://www.uni-muenster.de/ZIV/MeinZIV/index.html][MeinZIV]]) * You have to be a member of one of the 29 [[palma:projects][projects]] that may compute on Palma In this case, the user can be registered in [[https://palma1.uni-muenster.de/myJAM][myJAM]]. Here you also find an overview of the queues. Another tool for a graphical view of the queues is pbstop- The node for a worldwise ssh-Login is called palma.uni-muenster.de. If you wand to have a graphical login, you can use the [[palma:vnc][login via vnc]] You can also access your home-directory from other Linux-computers via [[palma:sshfs_english][sshfs]] If you have any questions regarding Palma, write an email to hpc@uni-muenster.de ---+ [[palma:rechnen:english][Computations on PALMA]] ---+ [[palma:software:english][Available Software]] ---+ [[palma:myJAM:english][The Webinterface myJAM]] ---+ [[palma:remote:english][Remote Visualization / GPGPU]] ---+ [[palma:tipps:english][Tips and Tricks for Palma]] -- Main.HolgerAngenent - 2010-08-16
