Calligo

Know Us

Calligo Technologies is a Bangalore-INDIA based start-up focused on development of products and solutions serving HPC, Big Data and AI/ML segments to global marquee enterprises. Established in 2012, focused in HPC/AI & Big Data from 2014 onwards.
The leadership team comes with collective experience of more than 100+ years with wide exposure to Compute, Storage and Semiconductor Industry. This has thus enabled them to look at the needs of the Compute & Storage industry comprehensively.
Calligo has been focused on developing Products and Solutions that are oriented towards the HPC, AI & Big Data solution for multiple industry segments. Calligo strongly believes in the future of HPC & AI as it is a critical pain point to be solved for large computational needs. The need for real time analysis / extraction of information on life threatening situations or to enlighten the leadership on analysis that would be a game changer in their business pushes the spectrum of the compute infrastructure to its extreme limits, eventually these infrastructures tend to become bottle necks limiting the compute ability in the state of consternation.
To address these limitations and overcome the pain point, the products and solutions from Calligo have been developed and implemented to various industries/enterprises.
Already an established player in parallelizing and optimizing of large HPC Software applications, CalligoTech is now working on improving Hardware of computing at grass-root levels. Towards this, the Company has developed co-processor capable of doing computations using a new number system – the Posit Number System (PNS) – invented in 2017. Calligo has integrated the Coprocessor with a RISC-V Processor creating a highly power-efficient, and computationally more accurate CPU core. We call it as CRISP-core (Calligo RISC-v with Posit). Complementing this hardware, CalligoTech has modified RISC-V C/C+/gFortran compilers to generate Posit-enabled executables, without need for any source-level changes. Linux OS booting, compilation and running of C/C++ applications with posit-enabled executables was demonstrated at many international events; RISC-V Event at Switzerland (June 2019),  HiPC Conference at Hyderabad (Dec 2019), at VLSID Conference at Bangalore (Jan 2020) and recently at HiPC 2022.
