Cell phones, MPI, and extending the boundaries of supercomputing

Jeff Squyres has a post to get your Friday morning off right in which he issues a challenge for someone in the community with a little free time to extend Open MPI…into your pocket! 

Jeff Squyres has a post to get your Friday morning off right in which he issues a challenge for someone in the community with a little free time to extend Open MPI…into your pocket

We’ve actually idly chatted about such things in the Open MPI community for a while.  It would be tremendously fun to write an iPhone/Android app that could talk to an MPI implementation and/or application.  Perhaps a good starting point would be to have the MPI implementation talk to an iPhone/Android phone.

Indeed, a simple first feature might well be push notifications when an MPI job completes. Open MPI supports “notifier” plugins  that exactly fit this use-case scenario.  We just need someone to write a notifier that sends an iPhone/Android push notification.

Any takers?  Ping me; I’d be happy to point you in the right direction.

An overdue update from the Diaspora team

The Diaspora team has put out an update on their progress in creating a “privacy aware, personally controlled, do-it-all, open source social network“. The project raised a fairly large sum of money to fund its efforts, and now it is reporting back. “We are spending a good chunk of time concentrating on building clear, contextual sharing. That means an intuitive way for users to decide, and not notice deciding, what content goes to their coworkers and what goes to their drinking buddies. We know that’s a hard UI problem and we take it seriously. The publicity and money that you have given us has let us work with great designers like Janice Frasier, through her new program LUXr, whose constant reminders that we are not the user have kept us honest and focused. Pivotal Labs has also helped us prioritize, and we have pushed back more technical features like plugins and APIs in favor of simple and high value features.

The Bidding War For 3PAR Continues; HP Offers $2 Billion In Cash

 Here we go again-again. HP just offered $2 billion, or $30 per share in cash for data storage company 3PAR. This morning, Dell announced that 3PAR had accepted its increased offer to acquire the storage leader for $27 per share in cash, or approximately $1.8 billion.

Dell had previously signed an agreement to acquire 3PAR for $18 per share or $1.13 billion, with a provision for matching competing bids. HP then effectively outbid the company and offered $1.6 billion, but Dell matched that offer yesterday, after which HP made a renewed bid for – you guessed it – $1.8 billion.

This latest offer nearly doubles Dell’s original bid for 3PAR. 3PAR provides a virtualized utility storage platform that enables customers to significant drive down cloud computing infrastructure, storage and associated management costs.

Review: ZaReason Verix Laptop

 

One of the challenges of being a Linux desktop user is the difficulty in finding systems that ship with Linux pre-installed. Major OEMs often offer a handful of Linux offerings, but to get a wider range of hardware and choices of Linux distributions you have to look to smaller vendors that are really interested in promoting Linux — like ZaReason.

ZaReason sells a full line of Linux machines, desktops, laptops, netbooks, and servers. They also sell peripherals and some other gear, but what I was most interested in was a laptop with Linux. Specifically, a laptop with muscle. So I asked ZaReason to send me a review unit, the Verix 1656 with Intel’s Core i7 and maxed out RAM.

 

The Verix comes with several choices of Core i7 chips, I got the 720QM, which has four hyperthreaded cores clocked at 1.63GHz, which means it shows up as 8CPUs on Linux. (At least according to top…) The Verix tops out at 8GB of RAM and includes several choices of hard drives. The model I was shipped came with an 80GB SSD, the first time I’ve used a laptop with an SSD drive instead of a 5,400 or 7,200 RPM SATA drive. It also included a Nvidia GeForce GTS 250M CUDA chipset with 1GB of RAM.

The screen is a 15.4″ LCD at 1680×1050, and it’s quite bright and crisp. I’ve seen laptops with a higher resolution, but it’s a good balance of size and resolution — a really good choice if you’re going to be working primarily on your laptop.

It’s a somewhat hefty laptop, but not too heavy. I used it pretty much from the minute I unpacked the box for a couple of days straight. It’s a nice balance between portable and powerful.

How’s it Work?

ZaReason shipped the Verix to me with Linux Mint 9 installed. This is the OEM version of Linux Mint, so the codecs and such are not pre-installed, but out of the box all that’s required is setting up the username and password and you’re ready to roll.

The dimensions of the Verix are 14.2″ wide by 10.3″ deep and 1.3″ high. It looks bigger than it is, possibly because they’ve managed to cram a complete keyboard onto the beast — including a 10-key that will make folks who do accounting happy.

One of the most important features on any laptop, in my opinion, is the keyboard and trackpad. How does the keyboard feel, is it solid, is the trackpad in the way or easily accessible when you need it and not prone to accidental input when you don’t need it? My favorite laptop keyboard of all time are the classic ThinkPad keyboards. I’ve owned or used at least 10 laptops extensively, and the only ones that have really made my fingers happy are the ThinkPads, which get an 11 out of 10 stars in my book.

How does the Verix fare? I’d give it a seven out of 10. The key spacing is good, and the action is passable. It feels a bit light, and the arrangement of the keys with the 10-key is a little off. I kept hitting the NumLock key where my fingers thought the Backspace key should be.

Performance was stellar. With 8GB of RAM, an SSD, and four cores of hyperthreaded goodness, the machine flew like the wind. Linux Mint 9 worked flawlessly on it, excepting the Webcam. That didn’t work right out of the box, which was a little disappointing. I pinged ZaReason tech support, and it turns out that the Webcam is not on by default and you have to touch a button above the keyboard to turn it on (or back off). This is a bit non-obvious, though, as the button just looks like an indicator light — odds are many users would never realize it’s actually a button without reading through the manual, and who does that? But the good news is that all of the hardware on the laptop is supported.

The sound on the machine is quite good, especially for a laptop. Speakers are clear and it’s a good machine if you need to rely on your laptop for tunes. Battery life is modest. Unplugged, I got about two hours of battery life out of the 6-cell, which is not so great if you’re needing a machine to work on long flights or other situations where plugging in isn’t an option.

Also worth noting that the laptop has an ExpressCard slot and a generous helping of USB ports (three), VGA and HDMI output (but not DVI) and audio input/output as well as a built-in microphone on the body of the laptop. The Verix also has a CD/DVD burner, and generally all the features most users would want in a full-sized laptop.

Price and Final Thoughts

As configured, the unit I tested was priced at about $2,200 — not including shipping or taxes. The Verix line starts at $1,499 with 2GB of RAM and the Intel Core i7 620M clocked at 2.66GHz. It looks like the base of the ZaReason Verix is the MSI 1656, which is rebranded by a couple of companies. The ZaReason pricing looks to be in line with other companies selling the laptop when considering the extras it shipped with when I tested it (SSD, 8GB of RAM).

The performance of the Verix was fantastic. The only disappointment was the video camera (which, frankly, I probably wouldn’t use except for testing) and the modest battery life. For road warriors who prize lightweight and long battery life over performance, this isn’t the laptop to choose. For those of us who travel occasionally and really want a system that has the horsepower of a desktop system but with the option of going mobile, the Verix should be at the top of the list.

And, it should go without saying, ZaReason is one of the companies that Linux enthusiasts should be shopping with first. They offer a great selection of Linux machines and selection of popular distros you won’t find many other places.

The Verix gets two thumbs up. It’s not perfect, but it’s a really good laptop and one I’d recommend to anyone who wants a solid and speedy Linux laptop. My main complaint with the Verix? It’s a review unit, which means I have to send it back. If you buy one, though, you won’t have that problem.

The People Who Support Linux: It’s a Family Affair

This is an ongoing Linux.com series that profiles The Linux Foundation’s individual supporters and begins to collectively illustrate a very important part of the Linux community. Individuals can help support the work of Linux creator Linus Torvalds and other important activities that advance Linux, while getting a variety of other fun and valuable benefits. It is this collective support that enables The Linux Foundation to provide important services for industry and community.

“My 7-year old has declared Linux is cool,” says Alex Hooper.

Alex is an individual supporter of The Linux Foundation and has been using Linux for five years. She started using it when she moved in with her partner, who is a programmer and built her computer using Ubuntu. Since then, Alex, her 7-year old son, her parents, and even the neighbor have all become regular Linux and open source software users.

“I am not a computer programmer or very skilled when it comes to figuring out what to do to make things work. So I need something that is easy and intuitive. I can load new applications, software and peripherals without having to look up manuals or finding that drive disc that always goes missing when you need it.”

Alex doesn’t use Linux at work but does at home, so she sees the stark contrast with other operating systems on a daily basis.

“I can make a coffee and take a couple of calls before my work computer is ready to function, but I am welcomed by the login screen after making my coffee at home,” she says. “I do a lot of artwork on the computer at home, which requires a fast dependable machine. The multiple desktop feature is extremely useful. I can have different windows for different tasks so that I don’t get cluttered.”

Alex said that she’s tried quite a few Linux distro’s on different laptops but today uses Ubuntu 9.04 Jaunty Jackalope. She also uses eeebuntu on her netbook. She says, “I have tried others and possibly need to upgrade to the latest distro. But it’s not broken, so why fix it?”

She is also running a variety of applications on her Linux computer, including OpenOffice, Firefox, Blender 3D, Audacity,Brasero, Amarok, Skype, World of Goo, and GIMP.

“GIMP has to be my favorite open source project. I am a freelance illustrator in my free time. When I was learning to use software to draw, I looked at the usual packages available and couldn’t afford to buy them. I found GIMP on the applications menu and thought I’d give it a try. Again, as is the case with all open source projects , it is very intuitive and I learned how to manipulate images and draw and paint on the computer. As a result, I have gained some commissions and sold some artwork in the process.”

The graphic used to accompany this article on the Linux.com frontpage was designed by Alex.

As for supporting The Linux Foundation, Alex says that she initially did it as a gesture to show her support for Linux but soon realized all the goodies to which she had access. “I’ve discovered many useful tutorials and how-to’s, and the community forums on Linux.com are extremely interesting and helpful.”

It appears that the family affair with Linux will continue into the next generation. Not only does Alex’s son think Linux is “cool,” but he’s also working on becoming the next in-house Linux expert.

“For his birthday, we refitted an old computer into a pretty case and set it up with Ubuntu with a changing desktop. We left him to it while we set about arranging the day and came back and found he had added several games to the computer through the applications tab. We were rather impressed he’d worked it out. I asked him how he did it and he said ‘it was easy mummy, do you want me to show you how to do it?'”

He is also the proud owner of a Tux T-shirt and is prepping his little brother for greatness.
