<br>
I am glad to hear that you are using the ZOO-Project and its OTB support even if it was not your original goal as you need to run the service remotely from the WPS server rather than running them directly on the same server.<br>
<br>
The work and the implementation you made looks very interesting and is a real asset to the ZOO-Project giving it the capability to be linked to a HPC infrastructure. So we welcome your contribution.<br>
<br>
Anybody can contribute code to the ZOO_Project, obviously if you need write access to the SVN then it will require that you are part of the ZOO-Project developers [1]. You should be member of the ZOO-Project PSC only in case you want to deal with the project organisation, plan and so on.<br>
<br>
Prior to ask the PSC for a vote, we should make sure that you agree with the committer guideline [2], once confirmed, I can then forward the request to the PSC.<br>
<br>
Hope to hear back from you,<br>
Best regards,<br>
<br>

> Hello,<br>
><br>
> My name is Rémi Cresson, I work in the field of remote sensing image processing. I am currently with french National Research Institute of Science and Technology for Environment and Agriculture (Irstea) to develop a geospatial data infrastructure for the GEOSUD project. I work mainly with c++ libraries (GDAL, OTB, ITK, GEOS, ...) for image processing pipelines development. A goal of the project is to use supercomputers for remote sensing data processing, binded with web services.<br>
> We tried Zoo because it was the only open source WPS server which has a friendly binding with OTB applications. We used it, and found that Gerald did a nice work (at least a very solid proof of concept). However, we needed to launch our programs from a HPC architecture (i.e. not programs 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.<br>
> I want to contribute to zoo-project with this service, and I might be interested to be PSC member of Zoo-project in a near future, if however this is an option.<br>

> Thank you for taking time to read this, I look forward to responses !<br>
