Optos is a leading provider of medical products and services to eyecare professionals. A collaboration between Optos, EPCC, and Intel has led to significant improvement in the performance of a software algorithm used in a product under development by the company.
The project set out to identify a suitably priced Intel multicore processor on which to run the company’s code, and to accelerate an important Optos machine-learning code. The project baseline was Optos code running on a specific Intel chip and the target was to reduce its runtime to below 12 seconds on the preferred chip.

Knights Landing MPI performance
Following on from our recent post on early experiences with KNL performance, we have been looking at MPI performance on Intel's latest many-core processor.
The MPI performance on the first generation of Xeon Phi processor (KNC) was one of the reasons that some of the applications we ported to KNC had poor performance. Figures 1 and 2 show the latency and bandwidth of an MPI ping-pong benchmark running on a single KNC and on a 2x8-core IvyBridge node.

Initial experiences on early KNL
Updated 1st August 2016 to add a sentence describing the MPI configurations of the benchmarks run.
Updated 30th August 2016 to add CASTEP performance numbers on Broadwell with some discussion
KNL is a many-core processor, successor to the KNC, that has up to 72 cores, each of which can run 4 threads, and 16 GB of high bandwidth memory stacked directly on to the chip.

I had a recent query from some users with a problem with the default version of the Intel Fortran compiler on ARCHER (v22.214.171.124). It was a nice query to get because the users had done all the work already; they'd identified the problem, found a test code that demonstrated it, and told me what the solution would be for them.
Fortunately, the solution was easy, this bug has been fixed in a newer version of the compiler (126.96.36.199), which is installed and available on ARCHER, but just isn't the default (we tend to keep the default version slightly behind the latest release but as new as possible), so they simply have to swap the compiler modules then their code can compile and run correctly.

Anyone taking more than a passing interest in HPC hardware recently will have noticed that there are a number of reasonably significant trends coming to fruition in 2016. Of particular interest to me are on-package memory, integrated functionality, and new processor competitors.
On-package memory, memory that is directly attached to the processor, has been promised for a number of years now. The first product of this type I can remember was Micron's Hybrid Memory Cube around 2010/2011, but it's taken a few years for the hardware to become mature enough (or technically feasible and cheap enough) to make it to mass market chips. We now have it in the form of MCDRAM for Intel's upcoming Xeon Phi processor (Knights Landing), and as HBM2 on Nvidia's recently announced P100 GPU.
