2017/04: SERB early career research (ECR) award, title: Secure and Reliable Non-volatile Memories for Ultra-low Power Applications
Open-source software released
1. DESTINY: DESTINY is an acronym for 3D design-space exploration tool for SRAM, eDRAM and non-volatile memory. DESTINY can model:
* (2D/3D) SRAM and eDRAM
* (2D/3D, SLC/MLC) STT-RAM, ReRAM and PCM
* (2D, SLC/MLC) SOT-RAM, Flash, DWM
In its purpose, DESTINY is similar to CACTI, CACTI-3DD or NVSim. Here are manual and the JLPEA 2017 journal paper. Source-code is available here. See its news coverage on ReRAM forum. Join DESTINY mailing list or see archive of previous conversations.
The proverb goes, write your own destiny. Hence, we have written our own [tool named] DESTINY. J
2. Both serial and parallel versions of code of red-black SOR (successive over-relaxation) method in three state-of-the-art languages, viz. Chapel (from Cray Inc.), D (also called dlang, from Digital Mars) and Go (also called golang, from Google) can be downloaded for academic use from this link. They were used in this paper. Chapel version of the code has been incorporated in Chapel performance test suite/examples.
