The HybriLIT heterogeneous cluster is a computation component of the Multifunctional center for data storage processing and analysis of LIT JINR, which contains a multicore component and computation accelerators: NVIDIA graphic processors and Intel Xeon Phi coprocessors. The detailed information on the heterogeneous cluster, rules and registration form can be found on the JINR HybriLIT Web-site.
With the HybriLIT team an agreement was reached on using the heterogeneous cluster and GOVORUN supercomputer for the NICA tasks. Once you have registered in the HybriLIT complex, you can login with your account:
ssh [username]@hydra.jinr.ru
Please, carefully read the important notes after login.
The external packages for the experiment software, FairSoft and FairRoot, were installed at the HybriLIT cluster, and you can use it by loading the corresponding modules:
export MODULEPATH="/cvmfs/hybrilit.jinr.ru/sw/slc7_x86-64/modulefiles:/cvmfs/hybrilit.jinr.ru/sw/slc7_x86-64/NICA/modulefiles" module add fftw/v3.3.7-5 module add FairRoot/18.2.0
If you have time-consuming tasks, many simple tasks or a lot of files to process, you should use batch system SLURM of the HybriLIT heterogeneous cluster and GOVORUN. For an access to the GOVORUN supercomputer run the following command
module add GVR/v1.0-1
Simple example of user job for SLURM:
#!/bin/sh
#SBATCH –ntasks-per-node=1
#SBATCH –mem-per-cpu=8192M
#SBATCH –time=3-0:0:0
#SBATCH -p cascade
module add FairRoot/v18.2.0_gcc485
