## GOVERNMENT OF INDIA MINISTRY OF EARTH SCIENCES LOK SABHA UNSTARRED QUESTION NO. 1481

## TO BE ANSWERED ON WEDNESDAY, 4 TH  DECEMBER, 2024

## TARANG FACILITY AT THE INDIAN NATIONAL CENTRE FOR OCEAN INFORMATION SERVICES

## 1481.  SHRI MANOJ TIWARI:

Will the Minister of EARTH SCIENCES be pleased to state:

- (a) the  key  features  of  newly  established  Tarang  facility  at  the  Indian  National  Centre  for Ocean  Information  Services  (INCOIS)  and  its  expected  contribution  to  oceanographic research and monitoring; and
- (b) whether the said facility will assist ocean scientists in enhancing the provision of timely warnings for tsunamis in the country and neighbouring countries and if so, the details of the mechanisms or technologies to be utilized to achieve the objective?

## ANSWER

## THE MINISTER OF STATE (INDEPENDENT CHARGE) FOR MINISTRY OF SCIENCES AND TECHNOLOGY AND EARTH SCIENCES (DR. JITENDRA SINGH)

- (a) TARANG is a 64-bit machine, capable of supporting multi-tasking, multi-programming, multi-user and time-sharing environment, of a proven architecture with scalable processing elements, scalable high performance I/O, scalable interconnection network and a balanced design  to  have  99.5%  uptime  with  adequate  redundancies  and  to  avoid  single  point  of failure  so  as  to  meet  the  operational  requirements.  The  HPC  system  is  supported  by technical  support  facilities  such  as  Transformers,  Diesel  Generators,  UPS,  Batteries, Multiple utility paths, Lighting system, Adequate no of earthing pits and Cables.

The compute capacity is about 1 Peta FLOPS, with a 2 Peta Byte storage and 3 Peta Byte archival  storage.  Additionally,  there  is  a  dedicated  standalone  system  for  Artificial Intelligence  (AI)  and  Machine  Learning  (ML)  applications  with  a  capacity  of  15.5  Peta FLOPS.

INCOIS will use the new system to run state-of-the-art ocean general circulation models, ocean-atmosphere  coupled  models,  and  wave  models  to  operationally  forecast  ocean variables  and  extreme  ocean  weather  as  well  as  to  meet  the  objectives  of  the  major initiatives  of  the  MoES such  as  the  Deep Ocean  Mission, the  Mission  Mausum and the Monsoon Mission within a year.

- (b) Yes. This facility will help INCOIS to provide Service Level 3 Tsunami warning Services in addition to early warning on Storm surges, High Waves, Swell Surge (Kallakadal) and Extreme currents. The workloads of TARANG include:
- (i) Operational models for providing Tsunami Early Warnings for India and other 25 countries on the Indian Ocean rim,
- (ii) Next generation Ocean State Forecast system with more accurate representation of physical  processes,  non-hydrostatic  dynamics,  high  resolution  nests  for  local forecasts and advanced data assimilation techniques and
- (iii) Developing  /  improving  sophisticated  models  such  as  MOM,  ROMS,  HYCOM, Wave Watch III, SWAN, Tunami N2, ADCIRC leveraging advanced technologies such as Artificial Intelligence and Machine Learning.

INCOIS will adopt AIML-based models to augment the quality of the forecasts using the available GPU processors. Further, the new computational facility will also be used for the numerical modeling of tsunami and storm surges aimed towards the improvements in their early warnings.
