Most supercomputers are focused on pure processing speed. Take the DOE's new Summit system, which is now the world's most powerful supercomputer, with 9,000 22-core IBM Power9 processors and over 27,000 NVIDIA Tesla V100 GPUs. But processing performa…

We are happy to announce that Partner Interconnect, launched in beta in April, is now generally available. Partner Interconnect lets you connect your on-premises resources to Google Cloud Platform (GCP) from the partner location of your choice, at a data rate that meets your needs.
With general availability, you can now receive an SLA for Partner Interconnect connections if you use one of the recommended topologies. If you were a beta user with one of those topologies, you will automatically be covered by the SLA. Charges for the service start with GA (see pricing).
In this blog we will walk through how you can start using Partner Interconnect, from choosing a partner that works best for you all the way through how you can deploy and start using your interconnect.
Choosing a partner
If you already have a service provider partner for network connectivity, you can check the list of supported service providers to see if they offer Partner Interconnect service. If not, you can select a partner from the list based on your data center location.
Some critical factors to consider are:
Make sure the partner can offer the availability and latency you need between your on-premises network and their network.
Check whether the partner offers Layer 2 connectivity, Layer 3 connectivity, or both. If you choose a Layer 2 Partner, you have to configure and establish a BGP session between your Cloud Routers and on-premises routers for each VLAN attachment that you create. If you choose a Layer 3 partner, they will take care of the BGP configuration.
Please review the recommended topologies for production-level and non-critical applications. Google provides a 99.99% (with Global Routing) or 99.9% availability SLA, and that only applies to the connectivity between your VPC network and the partner’s network.
Bandwidth options and pricing
Partner Interconnect provides flexible options for bandwidth between 50 Mbps and 10 Gbps. Google charges on a monthly basis for VLAN attachments depending on capacity and egress traffic (see options and pricing).
Setting up Partner Interconnect VLAN attachments
Once you’ve established network connectivity with a partner, and they have set up interconnects with Google, you can set up and activate VLAN attachments using these steps:
Google's Pixelbook is a high-end laptop that runs Chrome OS. If you're looking to do more with the hardware, like run Windows apps, you may soon be in luck. According to a report at XDA Developers (and picked up by 9to5Google), Google may in fact be…

Microsoft has given its infamous Office ribbon a much simpler, much less cluttered look as part of its interface redesign for Office.com and Office 365 applications. The tech giant has updated the element to only show the most basic options — if you…
Bluetooth is one of the most common method used to transfer the files between a mobile device and the computer, but many times the version of Bluetooth is not supportive which creates issues in connecting and transferring the files. While […]
For many of us, clean, drinkable water comes right out of the tap. But for billions it’s not that simple, and all over the world researchers are looking into ways to fix that. Today brings work from Berkeley, where a team is working on a water-harvesting apparatus that requires no power and can produce water even in the dry air of the desert. Hey, if a cactus can do it, why can’t we?
The secret isn’t some clever solar concentrator or low-friction fan — it’s all about the materials. Yaghi is a chemist, and has created what’s called a metal-organic framework, or MOF, that’s eager both to absorb and release water.
It’s essentially a powder made of tiny crystals in which water molecules get caught as the temperature decreases. Then, when the temperature increases again, the water is released into the air again.
They put together a box about two feet per side with a layer of MOF on top that sits exposed to the air. Every night the temperature drops and the humidity rises, and water is trapped inside the MOF; in the morning, the sun’s heat drives the water from the powder, and it condenses on the box’s sides, kept cool by a sort of hat. The result of a night’s work: 3 ounces of water per pound of MOF used.
That’s not much more than a few sips, but improvements are already on the way. Currently the MOF uses zicronium, but an aluminum-based MOF, already being tested in the lab, will cost 99 percent less and produce twice as much water.
With the new powder and a handful of boxes, a person’s drinking needs are met without using any power or consumable material. Add a mechanism that harvests and stores the water and you’ve got yourself an off-grid potable water solution. solution going.
“There is nothing like this,” Yaghi explained in a Berkeley news release. “It operates at ambient temperature with ambient sunlight, and with no additional energy input you can collect water in the desert. The aluminum MOF is making this practical for water production, because it is cheap.”
He says that there are already commercial products in development. More tests, with mechanical improvements and including the new MOF, are planned for the hottest months of the summer.
The Danish-Icelandic artist Olafur Eliasson and the Swedish furniture retailer Ikea are teaming up to produce a range of accessible and affordable tools that function without mains electricity and use renewable energy.
Eliasson’s Little Sun project, co-founded with Frederik Ottesen, created a solar-powered torch for the 1 billion people worldwide who live off the power grid. It is now sold cheaply in more than 600 African outlets. […] The products developed will be available in Ikea stores.
“Little Sun makes solar energy tangible and your world a little bit more sustainable,” Olafur said. “We are excited to collaborate with IKEA, raising awareness for energy access and the need for global togetherness. Together, we want to connect the world by sharing the power of the sun with everyone.”
