CoMet is an application for calculating vector similarity metrics on large-scale parallel accelerated computing systems to solve problems in computational genomics. Currently the 2-way and 3-way Proportional Similarity (Czekanowski) metrics, Custom Correlation Coefficient and DUO method are supported. Currently the OLCF Summit system and single GPU systems are supported. Dependencies include GCC, CUDA, MAGMA, MPI, CMake and googletest.
- Support for new architectures, including AMD MI100/MI250X and NVIDIA Ampere
- Support for INT4 and B1 precisions for NVIDIA Turing and Ampere architectures
- Up to 33% performance improvement for 3-way methods
- Option for lossless metrics data compression, allowing solution of much larger problems.
- Ability to set fine-grained output thresholds for different metric values.
- Option to calculate and output histograms of metric values.
See the file Quick_Start.txt for a step-by-step guide to building and running CoMet on the OLCF Summit system.
