Single-core vs. multi-core CPUs

In reviewing CPU and server benchmarks, you’ve undoubtedly noticed that testing covers both single-core and multi-core performance. Here's the difference.In terms of raw performance, both are equally important, but single- and multi-core have areas of use where they shine. So when picking a CPU, it’s important to consider your particular workloads and evaluate whether single-core or multi-core best meets your needs.Single-core CPUs There are still a lot of applications out there that are single-core limited, such as many databases (although some, like MySQL, are multicore).Performance is measured in a couple of ways. Clock frequency is the big one; the higher the frequency the faster apps will run. Also important is the width of execution pipelines, and the wider the pipeline, the more work can get done per clock cycle. So even if an app is single threaded, a wider pipeline can improve its performance.To read this article in full, please click here

Using ‘break’ and ‘continue’ to exit loops in bash

The commands for looping in bash are extremely useful. They allow you to run a series of commands as many times as needed to process a large collection of data. The break and continue commands provide another special option. They allow you to exit a loop early or skip the remaining commands in the loop and return to the beginning.Both the break and the continue commands are meant to be used only in for, while and until loops. In fact, if you try to invoke the break command on its own, bash will tell you just that.To read this article in full, please click here

IoT technology is hitting an inflection point for businesses

A new survey released by UK-based research firm Omdia bears out some of the industry’s rosier predictions for IoT uptake among businesses, finding that almost four out of five companies expect to be actively deploying IoT within the next two years.The survey, which was commissioned by IoT connectivity vendor MachineQ and collected responses from more than 200 enterprises in the manufacturing, retail, real estate and construction, healthcare and life sciences industries, also found that 70% of respondents said that they planned to have more than 50,000 IoT devices deployed within the next 24 months.To read this article in full, please click here

Nvidia strikes AI consulting deals with Deloitte, Booz Allen Hamilton

Artificial intelligence (AI) may be all the rage, but it's still slow to be deployed. The learning curve is steep, there are few people with adequate AI experience, and the rules of governance are unclear.That explains Gartner's 2020 statistic that only 53% of AI pilot programs actually make it to deployment. The tools and experience needed are just not there for the average IT shop, especially a smaller enterprise.Nvidia is looking to change that with a pair of AI-related alliances with consulting giants Deloitte and Booz Allen Hamilton. Both deals are designed to help companies plot AI strategies and gain access to Nvidia technology and expertise.To read this article in full, please click here

Broadcom’s VMware acquisition sparks concern

Chip powerhouse Broadcom recently announced its intention to acquire virtualization pioneer VMware for $61 billion. In light of Broadcom’s less than stellar track record with prior acquisitions (CA Technologies in 2018, and Symantec in 2019), VMware’s enterprise customers are understandably worried.“Following the purchases of CA and Symantec, Broadcom raised prices, decreased support, and stopped investing in innovation,” says Tracy Woo, senior analyst for Forrester. “VMware customers would be wise to have an exit plan,” she cautioned.IDC analyst Stephen Elliot sees it differently. Rather than advising VMware customers to identify the exits, Elliot believes customers should “double down” on their relationship with the vendor, moving towards a more strategic business partnership.To read this article in full, please click here
