Too small for him?

Today, I hereby officially baptize xAbhishek as a member of our doomed project. May he carry on our legacy of cluelessness!

Presentation on Programming the ANDC Cluster

Yesterday I and the other members of the cluster team did presentations on the ANDC cluster before an audience of teachers and students, mainly from the CS department of our college. The presentations were in the larger context of a 3-day workshop on GNU/Linux organised by our college. We were visited by Mr Amit Karpe and Mr. Dnyanraj Mali of Ascellent Technologies and Mr Niyam Bhushan, who has to be seen to be believed.

Dr Chauhan’s presentation was an overview of various clustering technologies, types and implementations. After that, Animesh and Ankit presented on the history of our (make-believe) cluster.

My presentation was on (parallel) programming the cluster before teachers and students in the college. Sadly, the presentation didn’t go to well, and quite a few people left in the middle of it. Also I could not talk about MapReduce and some more hardcore examples.

I’m still satisfied and happy, though, because I was able to learn a lot, from this, and that was the reason I got into this in the first place.

In case you (?) are interested, you can see the presentation here. Note that my presentation used the awesome Augie font by some guy. If you find some factual errors there, please comment.

I must mention the other presentations, by Vedant, xAbhishek and Priyanka. Nice to see enthusiasm from the nextgen :’-)

So we can now finally use 7 core2duo machines to calculate pi to values humans know are wrong. rah, science!

Suck Cess

Ok, so today I tried to set up a two-node cluster (using the nifty ParallelKnoppix, which is now sadly dormant) at home using my desktop as the master and my mom’s tabletPC as the only other node. I was able to get it to boot through the LAN using the noacpi cheatcode during PKsetup. I did a little digging through it to run some of its example MPI programs – The dartboard algorithm for approximating pi was pretty interesting, though I wasn’t able to get it to run more than 15 processes. (In fact, ever since I did that, I’ve been getting errors with every MPI program I try to run with more than 1 process :s ). While the results weren’t exactly spectacular

…But I was pretty excited to see all the nice figures.

Next up:
* Figuring out how to use Ether***t
* Replicating this ’success’ in the college ‘cluster’
* Running a few more benchmarks
* Getting Laid

Did I mention I have two tests next week on subjects I haven’t a clue about?

Etherbhootnika(#*@(#&@(&*^#@

OK so I’ve spent the last hour and a half :

a) Making my usb drives “read only” while trying to use dd
b) Burning a 500KB image onto a 700MB CD
c) Burning two floppy disk images.

in the vain attempt to load etherboot images on them. They better work or I will kill the prime minister. Or something.

It’s like being forcefed!

OK, short intro: We, students (?) of Acharya Narendra Dev College have been trying to redeem our academic selves by building a computer cluster. And score brownie points, maybe.

The sad part is we have made no headway in our disoriented, mismanaged efforts. So this blog-let is a sad attempt on my part to waste more time force some kind of order into the proceedings.
