Singularity Containers for HPC & Deep Learning
#Containerization as a concept of isolating application processes while sharing the same operating system (OS) kernel has been around since the beginning of this century. It started its journey from as early as Jails from the @FreeBSD era. Jails heavily leveraged the chroot environment but expanded capabilities to include a virtualized path to other system attributes such as storage, interconnects and users. #SolarisZones and #AIX Workload Partitions also fall into a similar category. Since then, the advent and advancement in technologies such as cgroups, systemd and user-namespaces greatly improved the security and isolation of containers when compared to their initial implementations. The next step was to abstract the complexity involved in containerization by adding user-friendly features such as templates, libraries and language bindings. LXC, an OS container meant to run multiple services, accomplished this task. In the late 2000s, @Docker, an application container that was meant to run a single service, took it one step further by creating an entire ecosystem of developer tools and registries for container images, improving the user experience of containers and making containerization technology accessible to novice Linux users. This led to widespread adoption. The evolving nature of this domain led to the creation of a standardization process called Open Container Initiative in 2015. Containerization drastically improves the “time to results” metric of many applications by eliminating several roadblocks in the path to production. These roadblocks arise from issues pertaining to portability, reproducibility, dependency hell, isolation, configurability and security. For example, applications in fast-paced growth areas, such as high performance computing (HPC) which include verticals and workloads like molecular dynamics, computational fluid dynamics, MIMD Lattice Computation codes, life sciences and deep learning (DL), are very complicated to build and run optimally, due to very frequent updates to the application codes, its dependencies and supporting libraries. Container images include the applications themselves and their development environments, which aids developers in porting their applications from their desktops to datacenters. This also helps with version control, making it easier to understand which versions of the software package and dependencies lead to a particular result. This, in turn, helps to manage dependency hell, which refers to the entire application failing if one of its dependencies fails. Another real-world example is collaboration between researchers, where containers help with reproducibility of the results. In short, instead of spending time debugging the software environment, researchers can focus on the science. Containers are orders of magnitude faster to spin up than virtual machines (VM) since they do not have a hypervisor providing a virtual hardware layer and a guest OS on top of the host OS as an independent entity. For a majority of HPC and DL applications, an un-tuned full VM may experience performance degradation when compared to bare metal. The overhead and performance degradation of a container when compared to an equivalent fully subscribed bare metal workload performance is nonexistent. All of these features have promoted the deep proliferation of container technologies.

iXsystems: 'weird' but profitable NAS vendor
Here’s something you rarely hear from high tech companies today: “We’re a hardware company in our heart and soul.” That is how executive vice president Brett Davis introduced iXsystems during a press tour in early December at the NAS vendor’s San Jose, California headquarters. The company sells open-source based TrueNAS enterprise hardware and FreeNAS desktop systems.
Self-identifying as a hardware company in this software-defined world is only one reason why iXsystems seems out of place in Silicon Valley. The vendor also bootstrapped its financing, turning a profit without accepting outside investment.
“We’re private, profitable and self-funded,” Davis said. “Our heritage goes back to the ‘90s. We’ve just been here. We say we’re unique, but you can say we’re weird.”
But it’s the hardware tag that provides most of the weirdness these days. The iXsystems headquarters includes a manufacturing facility in the back, where Davis said the 130-person company can fulfill 3,000 orders in a day.
The vendor claims more than 4,000 customers, including Sony, NBC, Duke University and NASA.
But the iXsystems strategy of bundling open-source storage software on commodity hardware isn’t that unusual. Plenty of others do that, and label it software-defined storage. But only iXsytems boasts it’s a hardware company even if its value comes from open-source projects.
The company’s roots date to Berkeley Software Design, Inc. (BSDi), which started in 1991. iXsystems founders founders Mike Lauth and Matt Olander acquired the hardware business from BSDi in 2002. Lauth has been the CEO and Olander the CTO since then. From the start, iXsystems was heavily involved in the FreeBSD project and is the project leader for FreeNAS Storage and TrueOS Desktop open-source operating systems.
Davis said 70% of @iXsystems appliances are custom configurations. The vendor uses @Intel, @AMD and #ARM chips inside. The systems support @VMware, @Microsoft #HyperV, #Citrix, @KVM and @OpenStack #virtualization software, #Hadoop, @Docker and #MySQL data and container platforms, and @FreeNAS, @FreeBSD, @CentOS, @RedHat @Linux and @Ubuntu #opensource software.
“We’ve been doing open source since way before it was cool,” Davis said. “We give away the number one software-defined storage (FreeNAS), but software and hardware are inseparable.”
iXsystems re-sold storage systems from Dot Hill, Infortrend and others in the late 2000s, but had to rely on those vendors for support. Now iXsystems provides end-to-end support for its storage. The company acquired the FreeNAS project in late 2009, and then spent two years re-writing the operating system before making it commercially available. iXsystems ported the OpenZFS open-source enterprise file system to FreeNAS. That gave FreeNAS file, block and object support, triple parity RAID, support for flash and unlimited instant snapshots.
@FreeNAS is file-only storage while @TrueNAS is unified storage with #FibreChannel networking support. TrueNAS competes with the likes of @DellEMC #VNXe and #Unity, @NetApp #FAS, @Hewlett Packard Enterprise’s #MSA2040 and @Nimble arrays, and @Western Digital’s @Tegile platform.
A more souped-up @iXsystems platform is planned for March with #NVMe support, but the vendor is staying quietly publicly about that for now.
Davis said iXsystems is staying out of hyper-convergence, even though it has all the pieces – including FreeBSD’s open-source bhyve hypervisor.
“We can run virtual machines and containers in FreeNAS,” he said. “We have the capabilities to do it, and we have our own hypervisor. But it’s a competitive space, and we have other plans.”

BSDTW ’17 Conference Recap
After 13 years, Taiwan is back in the BSD Conference spotlight. On November 11th and 12th, representatives from #iXsystems and more than 100 BSD developers, users, enthusiasts, and academic professionals from around the world came to Taiwan to participate in the 2017 BSDTW event, held at the Beitou Resort in Taiwan to discuss BSD. Co-hosted by the Open Culture Foundation (OCF) and Skymizer, the two-day conference was jam-packed with multiple presentations covering BSD technologies and projects. It was billed by the organizers as a venue “to exchange knowledge about the BSD operating systems, facilitate coordination and cooperation among users and developers, and to promote business-friendly BSD-licensed open source software.” At the start of the event, the organizers of BSDTW reported that attendance had exceeded their expectations and that all tickets were sold out. During this time, they also took the opportunity to thank the staff and sponsors of BSDTW. #iXsystems was both excited and proud to be a sponsoring company for this event. Other sponsors included @Microsoft and @Oath, a subsidiary of @Verizon. On the first day, the presentations by Johannes M. Dieterich on #HighPerformanceComputing ( #HPC) and #GPU acceleration, Peter Grehan on Graphics Support in #bhyve, and Allan Jude on #ZFS Advanced Integration were particularly interesting and thoughtful. Johannes gave an amazing overview on high performance computing, computer languages used, and @FreeBSD’s involvement in that realm. We learned that #FreeBSD needs a lot of work to compete in an HPC playing field that is currently dominated by @Linux. Johannes also discussed how he is using FreeBSD to develop software for HPC and what else is required to drive more FreeBSD deployments in HPC environments. Peter Grehan’s topic is something that we at iXsystems can relate to as we have been doing a lot of work around bhyve. Peter reviewed the history of graphics support in bhyve and the plans to add FreeRDP and spice support. After an inspiring first day, we gathered for a banquet dinner at the La Villa Danshui restaurant in the Tamsui District. Located in Northern Taiwan, Tamsui is a charming seaside town and a popular destination for tourists. Also, renowned as a place to view sunsets, it gave everyone the perfect opportunity to relax, unwind, and reflect on what we learned that day. The following day, OpenBSD founder, Theo de Raadt and FreeBSD developer Ruslan Bukin gave presentations that were particularly interesting. Theo gave a talk about mitigations and other real security features and explained how attackers can discover bugs in your software and what mechanisms one could use to prevent that from happening. Ruslan discussed his efforts to port FreeBSD to the RISC-V platform. He talked about the work needed to ‘make the system boot’ and then ‘be able to launch/run in a shell’. It was a remarkable project. His talk left quite an impression on us, especially this quote: “It is not common that a new computer architecture appears. It takes years. I worked very hard day and night so as to not lose this opportunity.” For many of us, one of the most enjoyable aspects of the conference was to meet and catch up with friends and acquaintances. We are looking forward to the event next year!
