Re: [Beowulf] Mobos for portable use

That is related to the end Moores Law. The shrinking of the transistor stopped increasing CPU speed in 2005 which brought about the release of multi core CPUS the fastest CPU ever release was at 4.5GHz in 2004. The newer i5 and i7 are quite a bit slower per core than the single core from the

We’ve made 2 board units in the past that fit in Pelican’s briefcase form-factor container, it was easy to use them in airports, the back of a VW Vanagon on the way to conferences, etc. Now with NVIDIA and others producing really nice, powerful, small boards boards Jim is correct, it’s

Re: [Beowulf] Mobos for portable use

some googling seems to indicate that the underseat 110V outlet is good for 75W. So a bucket of batteries - packaged so that each one is smaller than the DoT limit, will be needed to give that person in front the full 400W benefit. jim From: Beowulf

Re: [Beowulf] Mobos for portable use

The Little FE portable HPC cluster might be of interest on this topic. It is an HPC system build with small form factor motherboards to get a 6 node Beowulf cluster that can be powered off a standard 110 receptacle and used as a training system in public schools as it can be run in the

Re: [Beowulf] Mobos for portable use

Jim, I am a big fan of the Xeon-D but they take 45Watts for the CPU alone. Full featured Xeon and two 10gig ports on board though. I would be looking at one of the Nvidia boards intended for in-car systems. From: Beowulf [beowulf-boun...@beowulf.org] on

Some peeps have found the P50 to be ideal for mobile workstation: http://shop.lenovo.com/us/en/laptops/thinkpad/p-series/p50/ Xeon with 64GB of ram in laptop form. In the diy car computer and some other markets there are backpacks made to match up to common systems like the NUC to offer power.

This comes up every few years.. Someone at work was complaining at lunch that the latest laptops have nice screens but don’t have much memory, largely because they want to keep the battery size reasonable ("thin is in”).. my suggestion was “well, why don’t you just use your laptop as the user
