[Zoo-discuss] Introduction - Rémi Cresson

[nicolas bozon]

Hello Rémy,

Welcome to this list and thank you for such feedback and contribution.
It is very interesting to learn how Irstea is using and extending
ZOO-Project for the needs of the Geosud SDI.
As Gerald mentioned, please feel to share your services source code through
the ZOO-Project trac directly.
You are of course most welcome as new committer! Please accept the
committers guidelines on this list first so we can proceed.
IMHO, you would also be a great and valuable addition to the ZOO-Project
PSC. This will first take a request from the PSC Chair and then vote by
other PSC members.

Best regards,

Nick

> hosted by the WPS server as Zoo kernel do with OTB applications libraries).
> Indeed, we wanted to make use of our supercomputer's front node job
> scheduler in order to delegate resources management, job submitting, ...
> That leads us to implement a new Zoo service, which use ssh/sftp on the WPS
> server side and DRMAA on the HPC front node side. This new Zoo service
> basically transfert files between WPS server and HPC front node, construct
> a command line and submit a job, then transfert back files. We make it
> working with OTB applications only, using the same .zcfg files (but with
> another service name). We think the approach can be generalized to other
> existing processing libraries (Grass, ...). In addition, it can for sure be
> extended to parallel applications (MPI), as DRMAA can be used to dispatch
> process on a given number of nodes.
