IMDT for containers

Intel® Optane™ solid state technology offers a persistent media with capacity and pricing typical of disk drives but latency that is not so far from the memory. The Intel® Optane™ P4800X drive come with Intel Memory Drive Technology (IMDT), a software that allows extending the memory of a system using the solid-state drive, moving the Read more about IMDT for containers[…]

Using memory mapping to program Intel® Optane™ SSD drives

In this presentation are published experiments on accessing data on Intel® Optane™ SSD drives using memory mapping programming technique. Tests show that low latency and write time comparable with read time make Optane drive performing on a time scale comparable with the memory and offer a natural way to have persistent memory within programs.

Installation and testing of the Dual-port 25Gb/s Intel® Ethernet Network Adapter XXV710-DA2

University of Pisa is scouting a lot of new technologies for its Next Generation Data Center especially on the networking side. We have designed a new Data Center network based on the emerging 25Gb/s and 100Gb/s standards based on Dell* and Juniper* latest networking switches. During this activity (that involves a lot of R&D) we Read more about Installation and testing of the Dual-port 25Gb/s Intel® Ethernet Network Adapter XXV710-DA2[…]

High throughput disk access through the network

In the last six months or so we compared SSD drives from Intel using NVMe and SATA interfaces. NVMe (Non-Volatile Memory express) is a standard protocol over PCIe for accessing block devices such as disk drives. NVMe SSD drives benefit from direct access to the PCIe bus since the disk controller has become the bottleneck Read more about High throughput disk access through the network[…]

Hello world: not-so-optimal prime numbers

Previous post of “Programming XeonPHI using .NET and F#” series   In this post we start playing with the XeonPHI KNL system using F# and Visual Studio Code. The goal is to become familiar with the platform and see how simple, even inefficiently written, code performs on the platform. In this post series we will Read more about Hello world: not-so-optimal prime numbers[…]

Ninja for .NET with F# and Visual Studio Code

Next post of “Programming XeonPHI using .NET and F#” series   We recently received a XeonPHI Ninja developer platform (a pedestal liquid cooled unit) and started to play with it (for those unaware of the XeonPhi processor look at the quick summary at the end of this post); I was thrilled to test the second Read more about Ninja for .NET with F# and Visual Studio Code[…]

Bootstorm and VM disk access: NVMe vs. SATA

As solid state drives (SSDs) technology matures, the performance it delivers is constrained by old disk controller technologies. The NVMe protocol on PCIe interface allows you to bypass the controller by attaching directly a disk drive to the bus. In this report we present the results of comparing NVMe and SATA drives performance in the Read more about Bootstorm and VM disk access: NVMe vs. SATA[…]
