TinyGPU offers new hardware

TinyGPU has new hardware: tg010. The hardware configuration and the currently deployed software are different to the non-Fermi nodes:

  • Ubuntu 10.04 LTS (instead of 8.04 LTS) as OS.
    Note: For using the Intel Compiler <= 11.1 locally on tg010, you have to use gcc/3.3.6 Module [currently]. If not, is missing , as Ubuntu 10.04 does no longer contain this version. This is necessary only for compilation. Compiled Intel binaries will run as expected.

  • /home/hpc and /home/vault are mounted [only] through NFS  (and natively via GPFS-Cross-Cluster-Mount)

  • Dual-Socket-System with  Intel Westmere X5650 (2.66 GHz) processor, having 6 native cores per socket (instead of Dual-Socket-System with  Intel Nehalem X5550 (2.66 GHz), having  4 native cores per socket)

  • 48 GB DDR3 RAM (instead of  24 GB DDR3 RAM)

  • 1x NVidia Tesla C250 (“Fermi” with  3 GB GDDR5 featuring ECC)

  • 1x NVidia GTX 280 (Consumer-Card with 1 GB RAM – formerly know as F22)

  • 2 further PCIe2.0 16x slots will be equipped with  NVidia C2070 Cards (“Fermi” with  6 GB GDDR5 featuring ECC) in Q4, instead of  2x NVidia Tesla M1060 (“Tesla” with  4 GB RAM) as in the remaining cluster nodes

  • SuperServer 7046GT-TRF / X8DTG-QF with  dual Intel 5520 (Tylersburg) chipset instead of  SuperServer 6016GT-TF-TM2 / X8DTG-DF with  Intel 5520 (Tylersburg) chipset

To allocate the fermi node, specify  :ppn=24 with your job  (instead of  :ppn=16) and explicitly submit to  the  TinyGPU-Queue fermi. The wallclock limit is set to the default of 24h . The ECC Memory status is shown on job startup.
