Guerrilla computing in the mountains of Seattle
Hi, this is Garrett Kelly. I’m a senior engineer over at Brain Murmurs and I’m in charge of the Linux distributions of JIVA.
After rigorous testing of the Linux JIVA Client today, I am proud to say that we have a new product to add to our suite of supported platforms. The Linux JIVA […]

The JIVA Xscreensaver module has been updated and is running like a top under Fedora RC4.
This isn’t ready for prime time yet (the default RPM install requires some tweaks afterwards in order to run) but the heavy lifting work has been done.
It is worth noting that JIVA does NOT work with gcj. If […]

If you check out the network stats page you should see a few Linux and one of our Sun boxes reporting in. We haven’t updated the packages yet, so these won’t be ready to download for a few days, but they are cranking away.
The Xscreensaver build is being updated to our new codebase but […]

We have set up a public GForge site for JIVA, including a forums area and a bug tracker. It will be a couple of days until we get at Thawte certificate for the site, so there will be a certificate warning when you go to it.
You don’t have to have an account to read […]

The decision to implement JIVA applications in Java came down to one simple point: at this point in time, only Java byte code meets all of our requirements.
We knew at the start that the implementation depended on several forces, all in tension:
Performance
Mutability
Backwards compatibility
Developer acceptance
Customer acceptance
Security
Platform independence
Performance: Since the object of this exercise was […]

For us, security is king. In a volunteer grid system the computing software has to run on a computer that belongs to someone and is used for things besides supercomputing. I used to work as a network administrator at Kistler Aerospace. People are paranoid about their computers. People are suspicious of […]

There’s been a lot of hype about using virtualization for grid computing, so I decided to do a little bit of elementary benchmarking and see how VMWare stacked up against JIVA.
I decided to compare the performance of the Scimark 2 benchmarks running in three different ways (native, JIVA, and virtual native) on the same machine, […]

I was doing a bit of administrative work on one of our lesser used, Sun servers this morning and noticed that it had a hearty uptime of 288 days. Since this machines is a fairly slow but reliable JIVA Client as well I decided to look and see exactly how long the client had […]

We have an old SGI Octane here and I couldn’t resist setting it up with the JIVA Client. It is now arduously cranking away, looking for Mersenne Primes
If you are interested in seeing how it is doing, feel free to look at our server stats page

The idea behind JIVA are really not new: use the idle time of computers that you already own to solve supercomputing problems. If you have access to a lot of computers that are primarily used only during regular working hours you can use those machines to perform parallel computations.
I will try and illustrate […]
