Oncilla: A GAS Runtime for Memory Allocation and Data Movement in Clusters
Oncilla is a project that aims to provide a commodity-based, non-coherent managed global address space (GAS) runtime to support efficient data movement between host memory (DRAM) and accelerators (GPUs). Oncilla provides basic allocation and aggregation support for applications as well as support for multiple high-performance networking fabrics. Currently we support two network fabrics – the University of Heidelberg’s EXTOLL fabric and InfiniBand Verbs. Allocations and data movement are exposed to applications through the Oncilla API – a simplified interface built into a Linux shared library.
Current requirements for using Oncilla include the use of either IB (via the OFED software stack) or EXTOLL networking stacks (RMA2) and the use of CUDA for GPU allocations. Oncilla is currently hosted at Github, although please be advised that this is alpha research code. For more information on the Oncilla project, please refer to our IEEE Cluster paper that can be found in the list of publications.
