On this page we describe our experimental systems and benchmarks used for their evaluation. To support reproducible research, we make available the source code of systems and benchmarks used in experimental evaluation under open source license.


We develop PersistentDS, an open source NoSQL data store system. It’s main features are following:

  • strong consistency

  • acute replicated data types

  • effcient recovery after crashes

  • support of NVM

See research papers for details.


We use the following standard benchmarks:

For evaluation of crash-recovery we designed the following tests:


All software is available under open source license.


We conduct experimental evaluation using two computing facilties:

  • HPC cluster, equipped with Intel® Xeon® X3230 (4×2.66 GHz, 8 MB L2 cache), 1Gbps LAN (running at wire speed), OpenJDK 1.7.0_40, openSUSE 12.3.

  • EAGLE cluster, equipped with Huawei E9000 Blade Server, Xeon E5-2697v3 14C 2.6GHz, 56G Infiniband FDR Huawei Technologies Co., Ltd., 32 984 Cores, Rmax 1013.7 [TFlops/s], 1372.1 Rpeak [TFlops/s], 550 kW, located at Poznań Supercomputing and Networking Center (90th in the world’s TOP500 in June 2016).
