Resource centre NIIFI SC

NIIFI supercomputer is a fat-node HP cluster which is a very sophisticated type of blade technology CP4000BL. It is content the latest AMD Opteron 6174 type processors with 12-core Magny-Cours. Total number of cores is 768. It is using Infiniband network for the internal high-performance communication. The machine content 1.9 TByte memory and the computing power is 5.4 Tflops. Water-cooled rack was placed in the system to increases energy efficiency. This unique super computer run it very effectively in the mixed parallel programming paradigms and each node is a powerful 24 cores SMP computer.

Parallel programming models

Supported parallel programming paradigms are MPI, OpenMP, PVM and Hybrid.

Development software

Languages C/C++ ; gcc compiler toolchain, MPI libraries, profiling and debugging tools.

Infrastructural services

User administration, authentication, authorization, security

Users can access it with SSH public key authentication

Workflow and batch management

SLURM scheduler

Distributed filesystem and data management

There are two filesystems available to users (/home, /scratch) where /scratch is for temporary files created during job execution and it is shared beetween the worker nodes.

Accounting and resource management

Sun Grid Engine's accounting

Operational monitoring

Operational monitoring is performed using various tools: Nagios, Munin

Helpdesk and user support

User support is provided through dedicated hu_niifi queue at HP-SEE Helpdesk

Libraries and application tools

1) Software libraries:

PVM3, FFTW3, Blas, Lapack, MPICH2, OpenMPI

2) Development and application software available:

AMD compiler, GDB, GNU compilers (gcc, g++, gfortran)
