29th Annual Report (2016-17)

132 Power conditioning room for IUCAA Data Centre with UPS, battery banks and control panels In March 2016, a new High Throughput Computing cluster named “Sarathi” was acquired and installed for the exclusive purpose of Gravitational Wave data analysis. This cluster, with 2520 CPU cores, has a peak CPU computing capacity of 90 Teraflops. Further, 10 Tesla K40 cards in this system provide an additional 45 Teraflops of GPU computing power. The total storage capacity attached to this system is over 300 Terabytes. To support the power and cooling requirements of this cluster, 80 KVAof additional UPS capacity and a 28TR chiller was added to IUCAA’s existingData Centre infrastructure. The Thirty Metre Telescope (TMT), a segmented mirror telescope with a 30-metre filled aperture, will be the world’s most advanced ground-based telescope operating at optical and infrared wavelengths.An international consortium of institutions in the USA, Canada, China, Japan and India is building the telescope. About 70% of India’s contribution to the construction of TMT will be in-kind, and its share consists of both hardware and software. In software, India-TMT is responsible for delivering the Observatory Software (OSW) andTelescope Control System (TCS). The TCS is responsible for the coordination and control of various telescope subsystems through various project phases: (i) The preliminary design, (ii) The final design, (iii) The code and test, (iv) The integration and test, and finally, (v) The assembly, integration and verification at the telescope site.
