Hello,
I'm trying to get an instance of Galaxy working where the application server - the web front end, as I understand it - is on a completely separate host to the SGE cluster the back end runs on. Is there any way of setting up galaxy that it uses ssh instead of having to have the application server/SGE have a shared NFS filesystem?
Is having a shared filesystem the only way I can get Galaxy to work in this kind of scenario? We have a general-purpose cluster which doesn't export filesystems for security reasons, and doesn't run shared web applications.
Thanks for any help you could offer.
Hi Mike,
Unless you can add file-staging support to the DRMAA job runner, you need a shared filesystem. I had been under the impression that staging was not supported in the DRMAA 1.0, although it might be possible with the native spec field.
That said, there are some tools which write files to the working directory and those outputs are collected by the job runner, so if the working directory is not in a shared filesystem, these tools won't work properly. Unfortunately, I don't have a list of such tools, but there are quite a few.

Mike.
