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 SP1
Job Scheduler PBS Professional
Compilers Intel Compiler 11.1 (default), PGI CDK 12.9, gcc 4.3.4
MPI OpenMPI 1.4.2 (default), MVAPICH2 1.5.1
CUDA 4.1
CUDA driver 285.05.09

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
MPI MS MPI
