CIM 1U series HPC servers provide HPC performance in low-cost, 1U form-factors with total power consumption ranging from 200 to 300 W. These HPC servers include a dual, quad, or hex core x86 CPU and an OpenMP accelerator incorporating a CIM array. From a programming perspective, all cores -- both x86 and CIM -- appear uniform, with fine control over thread concurrency and core allocation.


Applications for CIM 1U HPC servers range from intelligent video to computational finance -- wherever there is a need for high performance computing within space and energy constraints. Examples include algorithm acceleration on UAVs and robots, blade servers, private server clusters or server farms where space and/or cooling is limited, telecom racks, and more.

Product Description

CIM 1U series HPC servers are designed for low-cost supercomputing applications. They minimize cost by combining mid-range Intel x86 CPUs and a very high performance accelerator. The first key to this approach is a small, low power accelerator, as opposed to large, power-hungry GPU boards. The second key is a flexible multicore programming model, instead of an API / library based approach such as CUDA. This is important because the cores in CIM series accelerators are CPU-style cores, capable of running arbitrary C/C++ code -- although heavily pipelined and containing advanced SIMD capability, they are basically similar in architecture to Intel rather than a GPU. CIM 1U series HPC servers are designed to make all cores look uniform. For example if the Intel x86 CPU contains 6 cores, and the accelerator an additional 64 cores, from a programming perspective they look the same; i.e. threads may run concurrently on all cores. Since the accelerator cores are better at numerical processing, it makes sense to designate compute-intensive source code sections to run on the accelerator, and general purpose source code sections (database, storage, user-interface, etc.) to run on x86 CPU cores.

Network Support

CIM accelerators support network sockets, which means that network communication can be included in source code sections designated for acceleration. This allows longer and more complete sections of code to be marked for acceleration; one example would be voice or video transcoding, where I/O data is in the form of IP/UDP/RTP streams. In that case, it's possible to run transcoding threads on the accelerator without data "touching" the motherboard and/or Linux, further increasing throughput gains.

Virtualization Hardening

Multicore resource management on CIM 1U series HPC servers is maintained on the accelerator allowing virtualization of server applications without loss in acceleration performance. For more information and theory of operation, click here

Core Allocation

OpenMP extensions supported by CIM software allow accelerator core to be allocated for (i) acceleration, (ii) task offloading, and (iii) user-defined purposes. The default is all cores allocated for acceleration. For more information and theory of operation, click here.
