Nokia 3.1 Plus comes out be a decent entry level smartphone as per Geekbench data

[Benchmark] Nokia 3.1 Plus comes out be a decent entry level smartphone as per Geekbench data

HMD’s Nokia 3.1 Plus first launched here in India last year. And while the pricing of the device left many in a predicament, the smartphone now looks like the worth of every penny. At least a recent benchmark score from Geekbench is in line with the above claim.

The Nokia 3.1 Plus was able to get 833 in a single-core test while in the multi-core testing it managed a score of 3516. This is…

Utilizing multi-core processor for classification in WEKA

Utilizing multi-core processor for classification in WEKA

Currently WEKA is one of the most favorites machine learning tools. Without programming skills you can do serious classification, clustering and big data analysis. For some time I’ve been using its standard GUI features without thinking much about performance bottlenecks. But since researches are becoming more complex by using ensemble, voting and other meta-algorithms that normally are based on…

World's First 1,000-core CPU that runs off an AA battery

World’s First 1,000-core CPU that runs off an AA battery

The United States Defense Department-funded researchers at the University of California, Davis, and at IBM have built a prototype 1,000-chip processor that they say is the most energy-efficient multi-core processor ever built.

Now, not only does the new UC Davis chip pack 1,000 cores, but the researchers also claim it is capable of being tuned to run off the equivalent of a single AA battery.…

Multicore JavaScript With Node.js

Multi-core processing is implemented by the Clusters module in Node.js. Since multi core processing in Node.js followings a process based model as opposed to a thread based one, there is no shared memory. So any data must be accessed or passed explicitly. This also means that each process has a large startup penalty because each one will require starting up the node vm to run the current script in a new process. So it is best used when there are a few long CPU intensive tasks.

The simplist way to demonstrate this is to split counting to 10 billion across multiple processes:

var cluster = require('cluster'), TOTAL = 10000000000; // spawn the child processes if (cluster.isMaster) { var cpus = require('os').cpus().length, part = TOTAL/cpus; for (var i = 0; i < cpus; i++) { let worker = cluster.fork(); worker.send({from: (i * part) + 1, to: (i + 1) * part}); worker.on('exit', function() { console.log('done counting for', worker.id); }); } // Do a count } else if (cluster.isWorker) { // Process is a global object built into Node.js process.on('message', function(parent) { console.log('counting from', parent.from, 'to', parent.to); for (var i = parent.from; i <= parent.to; i += 1); process.exit(); }); }

Note that they may not start or end in order.

2011 to present Intel CPU’s have run at about 3Ghz. Moores Law moved to multi-core. 2015 Phones and PCs are now quad-core. To move UX back to Moores Law we need more cores. This points at Android retooling for concurrency. Check out the Go on Mobile and Android cross-compile. Apple has to also retool NeXT objective-C for multi-core or give up the UX crown.

Solution: need high performance /bin/sort; any suggestions? #it #dev #answer

need high performance /bin/sort; any suggestions?

Greetings,

I’m looking for a high performance /bin/sort drop in replacement. I know there is pbzip2 for using multiple cores, but is there a similar product for /bin/sort?

I’ve found distsort.sh, but I want something less IO intensive. I’m looking to sort oh.. 60 gigs of data on a very frequent basis.

Why is my dual-core CPU recognized as a quad-core one?

My processor is an Intel Core i3-380m. As you can see, it’s 2 cores and 4 threads.

Although, both Ubuntu 11.04 and Windows 7 seem to think it’s a quad-core CPU:

Why is this? Is it because there are 2 threads per core, dividing the CPU in 4 processing units?
