Lightweight ally of workstations


As a user of only Debian GNU-Linux amd64, and for scientific purposes only, I am unaware of the new world of iphone/psd etc. However, I am trying to spare on the electricity bill by combining my CPU-GPU workstation (working without X-server) with the least power consuming device for e-mail and search/download of literature (pdf/html files). Such a device should be able to talk with the Linux boxes via passwordless scp, as a device on the internal network (router). The largest the storage and RAM mem of such a device, the best. Ideally, it should be able to run VMD and CHIMERA, software which allows viewing and elaborating PDB files and others. I imagine that the latter "ideal" would be hard to meet, as my output computational files range from 1.5 to seven GB.
Thanks for the advice. chiendarret

Light weight ally of workstations

This is a very useful suggestion. However, what about HMDI to VGA? The little I know is that it would not work with passive adapters. If so, the price of the adapter will approach that of the device you suggest. Therefore, as HDMI doe not improve in number crunching, it seems that the device you suggest was not made with scientific work in mind. They could have adopted a VGA interface and improve on other parts of the device. It will be very long time before we change from VGA.

Any other Linux-driven light weight ally of workstations? $25 is, per se, no attraction, in an area where multiples of $100 are the norm.

Thanks

Why? VGA is obsolete technology, whereas just about every TV set sold in the last 10 years has at least 1 HDMI socket. Same with monitors, even if a monitor DOESN'T have an HDMI socket HDMI is signal compatible with DVI and requires only an adaptor.

VGA interface: Only connect to devices with VGA.

HDMI interface: Connect to just about any TV and also output sound through the HDMI interface OR connect to any monitor with DVI with a simple adaptor.

Easy to see why HDMI makes more sense on the Pi.

Here's one with your VGA port and slightly better specs, but it's more expensive.

Lightweight ally of workstations

You can imagine that HMDI vs VGA is something known to everyone, in particular to the starter of this thread. The thread was centered on a companion device of number-crunching workstations.

At any event, in the meantime I came across a discussion pointing out that Ubuntu is looking for a hardware house to launch a Ubuntu-based high-end tablet. That would fill any need. I hope the project will ripe soon. In the scientific lab, existing tablets, android-based, ipads, etc are of no interest: from the laptop to the mainframe, the OS is Linux.

Cheers
