HybriLIT cluster (hydra.jinr.ru)

 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. It is designed for parallel computations asked by a wide range of tasks arising in the scientific and applied research conducted by JINR. 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 for the NICA tasks. Once you have registered in the HybriLIT heterogeneous complex, you can login with your account:

ssh [username]@hydra.jinr.ru

Please, carefully read the important notes after login.

 The FairSoft software was installed at the HybriLIT cluster, and you can use it by loading the corresponding module:

module load hlit/fairsoft/may16p1

To compile MpdRoot or BmnRoot, you should change SIMPATH variable (“export SIMPATH=/cvmfs/hybrilit.jinr.ru/sw/fairsoft/may16p1/sl6-gcc49”) in SetEnv.sh file of the environment.

 TIf you have time-consuming tasks, many simple tasks or a lot of files to process, you can use batch system SLURM of the HybriLIT heterogeneous cluster. If you know how to work with SLURM (SLURM on HybriLIT), you can use sbatch command on the cluster to distribute data processing. Simple example of user job for SLURM can be found in ‘macro/mpd_scheduler/examples/batch’ directory in our software.
Also, MPD-Scheduler was developed to simplify running of user tasks without knowledge of SLURM. You can find how to use it here.

 The data of the NICA experiments are located at the EOS distributed storage system of the HybriLIT cluster.
