Yes, I know I need to clean up the code, and remove unused (dead)
code. Can this wait for the next version I am working on, so I don't
do this clean-up twice? The version that is out there in testing
currently is v0.8. My development version is v0.9. I have been
distracted lately from finishing up v0.9, but its not far from being
complete. Mihael, when do you get back in town? <br>
<br>
If this is something more urgent, then perhaps I can get you a clean-up
version of v0.8 in the coming week.<br>

I've already looked at the Falkon code and it's... a lot of code that
does stuff that I understand only in principle. What you want isn't
easy, and I have my reservations towards the amount of fun it involves.
That being said, Ioan, would it be possible to have a cleaned up version
of the code where there are no duplicate classes? It's hard for me to
figure what's relevant or not in that case. And perhaps dead
code/comments removed?

What I think is important about Falkon is that its working, its
proving out the value of the provisioned direct-scheduling approach
with numbers, and that its working for Ioan as a vehicle for his
research.
What we want to get from the effort is a) Ioan progresses towards
his PhD; b) the immediate needs of our app-users get met; and c) we
learn whats needed in architecture, protocol and algorithm for a
successful long-term approach to running swift programs efficiently.
Point is that everyone is open to changes and towards an eventual
re-design and re-write. This, Mihael, would be where you can
propose, design and implement the ideas you've expressed about
implementing provisioned direct-scheduling using Karajan's remote
execution mechanisms.

<pre wrap="">It seems important that Ioan sit down with Mihael and work through the
Falkon code to see where it can be simplified, improved, etc. I am sure
that this will result in problems being identified and fixed that will
otherwise cost us time later.

<pre wrap="">Nope, I think this is a different problem, or at least a subset of the
problems we were having before.
Since we fixed the CPU utilization, and we moved to a bigger box (4
CPUs with 2GB of memory), everything is happening in a timely fashion
(a few ms per notification delivery throughout the experiment). Plus,
I believe the view is consistent (the same tasks look complete on both
ends) between Falkon and Swift, but we are still checking on this as
the run was made just last night for the 100 mol run. We'll keep you
posted with what we find.

<pre wrap="">The same problem that you showed me the other day or different?
with 'the same problem' being that falkon thinks all the jobs are done;
but that falkon's measure response time for sending completion
notifications gets approximately linearly longer over time and the swift
JVM uses ~100% and doesn't inidicate job completion at all after a certain
period.
or different symptoms now?
