[Saga-devel] Tests for Saga-Cloud paper

[Katerina Stamou]

Dear Shantenu, Andre,

This is an update (yeah almost 24 hrs before the paper submission) of
the progress regarding the experiments we intended to conduct with
Saga-MapReduce in GumboCloud and LONI clusters.

In a quick chat with Shantenu yesterday afternoon, I've explained the
necessity of turning from GumboCloud to Amazon EC2 in order to conduct
the experiments, mainly due to the fact that the current installation
and configuration of Eucaliptus in GumboCloud (and although Andre
tried to fix things even at this very last moment) hasn't and still
doesn't allow to actually utilize it even to run a simple test. The
causes are out of my concern, and I think it was really useful that at
least both Andre and me investigated and possibly helped to improve the
current status of this service. Since, yesterday morning, I've been
trying to set up an image for the Amazon EC2 in order to conduct the
tests there. This resulted to be a more difficult effort than initially
thought, mainly due to the fact that I had to setup everything from
scratch, and overcome various installation hurdles with mismatching
software versions and the like.

I'm currently at the point where everything should be set for running,
but for some reason when the master worker launches the agents on the
ec2 instances, it just waits there forever with no output. From the
other side of things (inside the vm), the worker appears to be having
some trouble. Looking more into it right now, and will send out a mail
later or tomorrow morning for the debugging details.

As I had stated from the very beginning of this effort last week, I
couldn't promise for the accomplishment of our goal, since I am really
in Cloud Computing, as well as the relevant Saga implementations
(Saga-MapReduce, relevant adaptors, etc) are really new and of course
not well tested also.

To sum up, I would like to first of all say that I'm really sorry for
not being able to sufficiently contribute in the current effort. I
really wish I had more time, and I know that I will have a lot of time
in the future not only to conduct such trivial tests but also offer to
the Saga-Cloud and MapReduce efforts regardless of this paper.
Although, I ll keep continue setting up this image in EC2, it would be
mythical to say that I'll manage in time to run the experiments and
comment on them in the paper (as human-weak being I also have to sleep,
and go to school ;-) ), and I don't know if it would be valuable for
further efforts to report what I've done so far.

It will be a quite tough day for me today to schedule a possible
telecon through Skype, as I have to attend several classes and decide
eventually which one to participate, but I'll be online on aim and I'll
keep reading emails.

Shantenu, Andre -again my apologies for missing the our final goal, I
really did the best I could in such little amount of time.

Best,
Katerina
