[Swift-user] Question about swiftR temporary and work directories

[Lorenzo Pesce]

Yes, lustre will of course gel up and then freeze =)

You are right. I just wanted a way to change it in case I get a ramdisk explosion. =)

In fact  I am trying to use ramdisk with some other swift apps I am working on. 

Thanks a lot both for the answer and the advice.

It isn't necessary that this temporary directory be visible to nodes in the cluster, since it is just used for temporary storage for the local processes. Many small files are created in the directory, so I have no idea how it will work with lustre.
