Thank god you guyz disscussed it after i left. BTW
what was stopping you from discussing it while me and
shejar were around??
Well here is the outcome of our sunday morning
adventure.
Flashmob iso bombed (as i expected). It appears to be
flaky and not performing properly with Intel hardware.
The results we got were vaying. We could achieve 1.9
Gflops on single machine, but when we extended cluster
to 3 nodes the Gflops fell to 0.5 Gflops.
Flashmob iso was ruled out (unanimosly) due to flaky
behaviour and non availability of source code.
Following this new action plan was drawn. We decided
to go for our iso. After some R&D we got on with the
job. I was carrying an educational cluster ISO which
worked but there were no tools prtesent in the ISO to
benchmark the performance. (we only tested network
latency and stability and results were satisfactory).
Manpreet started working on making a cluster using
PCQLinux 2004(pre installed) as Anindya promised to
make an live CD out of it.
We were able to create a master node on PCQLinux, the
problem started while creating the slave. One of the
packages (we had a collection of packages to make
cluster on RH6.2) required postgresql version 5.x and
we had version 7.3 installed.
By this time it was already 1:30 p.m and we had 4
crashed brains. So, we decided to continue this next
weekend. Hopefully we will have a an ISO to do the the
testing work next week.
