Today IBM has announced "SuperVessel", an OpenStack based cloud service that enables students and developers to develop applications on a POWER 8 based infrastructure. What makes this cloud service interesting is the announcement that Hemant Dhulla, Vice President of Data Center and Wired Communications for Xilinx made:

Xilinx is delighted to have been chosen as the provider of FPGA accelerators for the IBM SuperVessel cloud. FPGA-based compute acceleration is a critical part of the OpenPOWER Foundation vision to handle demanding workloads in the most cost and power-efficient way. For this reason, a CAPI-enabled Xilinx FPGA is attached to every IBM POWER8 node in the SuperVessel cloud. The research and development being done in the SuperVessel is helping to define the future of heterogeneous computing.”

FPGAs, or field-programmable gate arrays are traditionally used to perform a specific algorithm in hardware. The result is a bulky and expensive chip (produced in low quantities) that runs a certain algorithms at very high speed and low latency. 

Offloading some processing tasks to a specialized chip is certainly nothing new. APUs are CPUs that offload some of their tasks to integrated GPUs. But quite a few parallel algorithms run fast but pretty inefficiently on GPUs. In many cases, an FPGA uses a lot less power. 

Intel has been delivering "customized" Xeons to large customers such as Amazon en Facebook, and has been promising that it will integrate Altera FPGAs inside certain Xeons.  Intel recently bought Altera for $16.7 Billion. 

But IBM seems to have beaten Intel to the FPGA punch with CAPI, the POWER8's Coherent Accelerator Processor Interface. IBM does not integrate FPGA inside the POWER8 package (yet), but communicates coherently over the PCI express interface. 

The most interesting fact about "Supervessel" that is IBM has managed to make a cloud service that makes ample us of - traditionally expensive - FPGAs, and that the necessary software is in place to make it relatively easy to make use of those FPGAs.  What software did IBM implement to make offload some of the processing work to the Xilinx FPGAs? Unfortunately, so far we only saw the press release and it is very light on technical details. Nevertheless, it is interesting to note that the OpenPOWER Foundation is making a lot of progress in very little time - it was founded only at the end of 2013.

    How much longer until IBM buys Xilinx?

    the experience from the Netezza department, integrated with the power of the Power8 architecture and delivered to general purpose environment, brilliant!

    Looks like the marketing department was a bit too quick. The site is half in Chinese, you can't really sign up etc.. I'm always amazed how abysmal these large companies are at building a somewhat useful web experience.

    Maybe they wanted to rush the announcement because of all the Intel + Altera news. That's a pretty big deal in the FPGA space.

    They have started its marketing way too early I reckon, let's talk about FPGA or a field programmable gate arrays being used in CAPI; This seems a very intelligent modification by IBM and it would be far easy for the developers to use natural programming more rather than FPGA's commands only. SuperVessel cloud uses inside in every node of Power8 chips that will boost the FPGA's. Looks like a good challenge for Intel Corp. More FPGA command lines and assignments fo visit Thank you!

    Great post because this new technology is making rapid progress in such a short spam of time. For more details visit

    This is great to see that IBM created an educational cloud which helps student in so many ways. It may support higher learning institutes as which is also busy in providing assignment help for cheap law assignment writers
