SAGA 220~ INDIA's Supercomputer used for Solving Complex Aerospace Problems


By : NGWT
SAGA-220 (Supercomputer for Aerospace with GPU Architecture-220 teraflops) is a supercomputer built by the Indian Space Research Organisation (ISRO). It is used by space scientists for solving complex aerospace problems.
"SAGA-220" Supercomputer is fully designed and built by Vikram Sarabhai Space Centre using commercially available hardware. The supercomputer is loaded with open source software and ISROs own innovative complex aerospace application for the design and analysis of aerospace vehicle configurations. The system uses 400 NVIDIA Tesla 2070 GPUs and 400 Intel Quad Core Xeon CPUs supplied by WIPRO with a high speed interconnect (Mellanoxs InfiniBand network). With each GPU and CPU providing a performance of 500 GigaFLOPS and 50 GigaFLOPS respectively, the theoretical peak performance of the system amounts to 220 TeraFLOPS. The present GPU system offers significant advantage over the conventional CPU based system in terms of cost, power and space requirements. The total cost of this Supercomputer is about Rs. 14 crores. The system is environmentally green and consumes a power of only 150 kW. This system can also be easily scaled to many PetaFLOPS (1000 TeraFLOPS). Over 100 engineers can work simultaneously on SAGA-220 at any time.

By: Next Generation Weapons Technology Network Centric Warfare and Indian Navy & IAF and land based units. More satellites will be launched as grid as launched previously. In addition to making platforms and infrastructure for network centricity, the Navy has also made organizational changes to create and efficiently manage the transition to seamless Network Centric capabilities. The creation of a new post of Assistant Chief of Naval S taff (Communications Space and Network Centric Operations) is step in the process to migrate from a ‘Platform Centric Navy’ to a ‘Network Enabled Navy’. During various exercises, Network Centric Warfare (NCW) has been one of the crucial aspects being validated. During the various coordinated exercises conducted by the Army with the Air Force, the endeavor has been to validate and integrate the use of all available assets, including satellites, UAVs and HUMINT (Human intelligence) to assist commanders at all levels in taking dynamic and pr

The Heat is on!! for INDIA as China Unveils its 5th Gen Stealth J20 Fighter Jet ; Pakistan expresses interest to buy

Image
China on Tuesday unveiled its J-20 stealth fighter jet at its biggest air show which will have major implications for India as it is the first indigenously-made fifth-generation Chinese aircraft which Pakistan has shown interest in acquiring. Two J-20 aircraft which made waves in the Chinese media in the last few years flew at the Zhuhai city air show where the Pakistan Air Force is also taking part flying with its J-17 Thunder jets which are jointly manufactured with China. This is the first, public show of the J-20 warplane. Pakistan, the largest importer of Chinese arms has said earlier that it is in talks with China to buy the FC-31 - an export variant of the same aircraft. The FC-31 was briefly flown in the 2014 Zhuhai airshow. The stealth aircraft is regarded as major breakthrough for China which is otherwise mostly reliant on Russian aircraft including advanced versions of Sukhois. India is yet to make stealth aircraft which can penetrate through enemy radars. The J

Where Is Article 370 Now!!!!, That Rohingyas And Bangladeshis Are Being Settled In Jammu And Ladakh ???

Image
Jammu is up in arms against the authorities. This time, it is not against discriminatory policies being pursued by the successive Kashmir-dominated and Valley-centric governments in Jammu & Kashmir since 1947, but against the settlement of Rohingyas from Myanmar in Jammu and Ladakh, both strategically vital for national security. According to the late Jammu and Kashmir chief minister, Mufti Mohammad Sayeed, the number of Rohingya Muslims living in different parts of Jammu city and around it, was 5,107 in 2010 (AINS, 10 October 2015). And, as per Chief Minister Mehbooba Mufti’s June 2016 Assembly statement, there were 13,400 Rohingyas and Bangladeshis living in camps in Jammu. She said “Bathindi Ka Plot is home to the highest number of Rohingya Muslims” (The Hindustan Times, 5 December 2016). The break-up of Rohingyas settled in the state is as follows: Jammu – 5,086, Jammu’s Samba district – 634 and Ladakh – 7,664. The total number is 13, 334. The Jammu Chamber of C
