Adding Lustre Storage to the HPC Equation

For organizations that need extreme scalability in high-performance computing systems, Lustre is often the file system of choice — for a lot of good reasons. When it comes to high-performance computing applications, there is basically no such thing as too much data storage. Who doesn’t need more storage? Everywhere you look, HPC applications are ballooning in size. A few examples: AccuWeather, the world’s largest source of weather forecasts and warnings, responds to more than 30 billion data requests daily.[1] The wave of medical data washing over the global healthcare industry is expected to swell to 2,314 … READ MORE

Making AI, HPC and GPUs Easier for Data Scientists

With new GPU-ready containers and server infrastructure, organizations are simplifying the deployment of artificial intelligence applications and the clusters they run on. Regardless of the domains they work in, researchers, data scientists and developers want to focus on the work they do, not the systems and tools they use to run their workloads. While that’s a simple proposition, the reality on the ground is often far removed from this ideal world. Those who have built artificial intelligence and other high-performance computing applications from the ground up — starting with bare-metal servers, computing frameworks, software libraries and … READ MORE

The Hottest Cooling Technology for Demanding HPC Systems

EMC logo


As high-performance computing systems incorporate higher-wattage processors, liquid cooling is gaining momentum. The annual Supercomputing (SC18) conference is always a great showcase for leading-edge technologies for high-performance computing, and that will certainly be the case this year as SC18 gets underway in Dallas next week. One of these technologies in the spotlight will be liquid cooling, which is emerging as one of the keys to even-more-powerful HPC systems. A convergence of trends is fueling the momentum for liquid cooling. For starters, the thirst for higher throughput in HPC clusters is unquenchable. With every new generation of … READ MORE

Smart Devices and Services Are Driving Edge Computing. Is Your Organization Ready?

EMC logo


The fourth wave of computing is being driven by a combination of forces – organizational demands to increase revenue, profitability, and serve customers better as well as robust use cases that can be solved by the latest technology advances. The first wave of computing started with centralized mainframes, the second wave swung to distributed use of client-server-PCs, and the third wave shifted back some to centralized cloud computing. Now, the fourth wave, which is also called “distributed core” or “fog computing”, distributes computing back to the sources of data and consumption of services. Operational Efficiency Operational … READ MORE

Edge Computing: The Driving Force in New Architecture Innovation

EMC logo


Edge computing is a very widely used term these days in lot of technology blogs, analyst reports, conferences and product announcements. Many companies are positioning themselves to grab a share of the edge computing addressable market. A lot of announcements try to position their existing products for edge deployments and few try to innovate for purpose built edge architectures. With so much noise in this space, it is hard to distinguish real innovations from small modifications in existing products. The companies that drive real architecture innovations for new distributed paradigm of edge computing and integrate it … READ MORE

7023357: Studio onsite: Users are unable to edit appliance

This document (7023357) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Studio 1.3

Situation

After an unclean shutdown (power outage) users are unable to edit or create new appliances
After login to webUI following error is shown:
Could not get the setup status.
After trying to edit/create an application within webUI a message in red is shown:
Software failure. Press left mouse button to continue - unable to call sid @ 127.0.0.1:3008...
Port 3008 is httpd and trying "rcstudio_sunspot_solr restart" will show you a message that
it is unable to connect to 127.0.0.1:27017 which is mongodb.
rcmongodb restart will show that there is a file lock probably from an unclean shutdown

Resolution

Remove the mongodb file lock, then try to restart mongodb:
rm /var/lib/mongodb/mongod.lock
rcmongodb restart
Afterwards restart of the services rcstudio* is required.

Cause

Due to unclean shutdown mongodb was unable to recover and removing the file lock.
