Re: [alto] IETF 114 ALTO Hackathon projects

Hi all,

During the weekly ALTO meeting today, we discussed the coming hackathon and
Qin suggested that we send an update to the mailing list on the FTS+ALTO
project, and here is the update:

- In short, if you want to work on ALTO integration with production, open
projects, this can be a wonderful project to work on: it may help both ALTO
(in terms of its crucial deployment mandate) and the largest data-intensive
science projects at CERN.

Specifically:
- For those who have not tracked the hackathon, as Jordi said, it is a
continuation of the 113 Hackathon.  In particular, the 113 Hackathon
focused on the integration with Rucio, which is a wonderfully designed tool
used widely in CERN and some other projects for data movement of a large
amount of data (PB -> EB). In 113, the hackathon modified the manual
workflow, which is the workflow to select the source to download a dataset
when a client issues a download command. The other workflow of Rucio is the
automatic workflow, which selects the sources and destinations to realize
user-specified replication rules. In our original plan, 114 would focus on
the automatic workflow. However, the team realized that Rucio is built on
top of FTS, which is the main tool used at CERN to schedule which transfer
is scheduled at what time, where Rucio is at a higher layer providing the
transfers for FTS to schedule.

- The 114 hackathon includes 2 objectives: (1) introducing resource control
to FTS, and (2) evaluating an alternative design of FTS core: the FTS
Optimizer. Hence, the work includes 3 components, integrating the FTS
production code and framework:
(1/basic) allow FTS to specify resource control goal and use ALTO to map
FTS control state (called links in FTS, where a link is a pair consisting
of a source node to a destination node, where a node is called RSE) to
network state;
(2/basic) implement a full zero-order algorithm, to achieve fully
efficient, zero-order gradient control as FTS Optimizer;
(3/stretch) realize a composition framework to compose end-to-end resource
performance function, including both zero-order and first-order gradient,
covering the bottleneck structure.

The project is exciting both in terms of its technical content and also in
terms of its potential impacts. The hackathon project will work under the
guidance of the Rucio project lead (Dr. Mario Lassnig) and the FTS project
lead (Mihai Patrascoiu and Steven Murray); all cc'd in this email. This can
be a wonderful opportunity for IETF, the networked systems community and
the data-intensive sciences communities to work together.

Please feel free to reach out to us (Jordi, Mahdi and me) if you want to
join the hackathon or later.

Thanks,
Richard on behalf of the IETF 114 ALTO+FTS Hackathon Team
