Tried working on the Linux cluster today. ROCKS is a super good environment for working with MPI. Every command you type as a user is automatically run on all available nodes. File changes are synched instantly. I highly recommend ROCKS for MPI users.
Unfortunately, this is not the ideal testing environment for my system as the client machines need a different configuration than the cluster manager - and I don't want work to be created on the clients in parallel. :( Doing some thinking at the moment about how to get around this. I could use a portion of the non-replicated file system... still it is mighty inconvenient.
Oh yeah, trying to do transactions in a SQLite DB on the NFS shared FS produces a segmentation fault :( I knew the locking was broken on directory structures that are shared, but I didn't think it would go down like that. The best case scenario says that I should get a DB is locked error or something like this.
