UCX Report from SC15 !

Monday, November 23rd, 2015

We want to thank UCX community for a fantastic participation in SC15 events. This is the first SC conference when we had UCX Birds of a feather (BoF) session. We would like to thank ORNL, ANL, LLNL, LANL, USG, Nvidia, IBM, and Mellanox in active participation in this session. The session was followed by a panel were UCX advisors have been answering question from the community.

“UCX: An Open Source Framework for HPC Network APIs and Beyond” paper was presented at IEEE HOTI 2015 Conference

Thursday, August 27th, 2015

Pavel Shamis (Pasha) from Oak Ridge National Laboratory presented “UCX: An Open Source Framework for HPC Network APIs and Beyond” paper at IEEE HOTI 2015 conference.
“This paper presents Unified Communication X (UCX), a set of network APIs and their implementations for high throughput computing. UCX comes from the combined effort of national laboratories, industry, and academia to design and implement a high-performing and highly-scalable network stack for next generation applications and systems. UCX design provides the ability to tailor its APIs and network functionality to suit a wide variety of application domains and hardware. We envision these APIs to satisfy the networking needs of many programming models such as Message Passing Interface (MPI), OpenSHMEM, Partitioned Global Address Space (PGAS) languages, task-based paradigms and I/O bound applications. To evaluate the design we implement the APIs and protocols, and measure the performance of overhead-critical network primitives fundamental for implementing many parallel programming models and system libraries. Our results show that the latency, bandwidth, and message rate achieved by the portable UCX prototype is very close to that of the underlying driver. With UCX, we achieved a message exchange latency of 0.89 us, a bandwidth of 6138.5 MB/s, and a message rate of 14 million messages per second. As far as we know, this is the highest bandwidth and message rate achieved by any network stack (publicly known) on this hardware.”

UCX Collaboration is formally announced at the ISC 2015

Wednesday, July 22nd, 2015

We are super excited to announce that the UCX collaboration was launched at the 2015 International Super Computing Conference ! The launch was featured at HPC Wire, Inside HPC, and ORNL ! We want to thank all the member for their support in the development of this collaboration. The access to the github is open for everybody and the community is more than welcome to join and contribute. We just started and everybody has the opportunity to define and influence the API, designs, and software architecture. Happy Hacking !
