TSUBAME2 Software Architecture

TSUBAME2 provides both Linux and Windows operating systems on its compute nodes. The basic software components are listed below. Application informaiton is available here.

Linux Compute Nodes

OS SUSE Linux Enterprise Server 11 SP3
Job Scheduler PBS Professional
Compilers Intel Compiler 2013.1.046 (default), PGI CDK 15.1, gcc 4.3.4
MPI OpenMPI 1.6.5 (default), MVAPICH2 2.0rc-1
CUDA 6.5
CUDA driver 340.29

WARNING: While most TSUBAME1 programs won't need to be rewritten just for running on TSUBAME2, recompilation on TSUBAME2 is highly recommended because some libraries are installed at different paths

Windows Compute Nodes

OS Windows HPC Server 2008 R2
Job Scheduler Windows HPC Server
