Question How are you running your nfs jobs

I'm assuming that most of here are running GGNFS for the sieving with msieve for the post-processing, but I'm wondering how you're running it.....

I'm fortunate in that I have access to lots of hardware... a 300 node opteron cluster, another 30+ node core2 Xeon cluster, and sundry other smaller fodder, all on different networks and running different OS's (mostly *nix), and all with various other loads from other users that I need to respect. My main problem is keeping them busy with relevant work while not stepping on other people's toes. I've written many scripts to help, but there is still a lot of management that I struggle to keep up with.

anyhoo, it's good fun.

As an added point of info, I would define multi-core or networked PCs as using one of the scripts and sneaker-netting as performing manual (or special purpose script) assignment and transport/merging of relations.

I run most NFS-jobs on a stand-alone-PC (Core-2-Duo-Laptop), the smaller ones (up to ~c117) are running automatedly (gnfs.ub, most GNFS'es currently coming from aliquot.ub) on one of the cores.

For larger jobs I use both cores of the laptop and sneakernet (USB-stick) some additional relations from my P4.

Additionally I have contributed to fivemacks huge NFS-jobs, sneakernetted the relations to my home Pc and uploaded them to fivemacks ftp-server. (I don't know if I can continue contributing to these projects as the numbers start getting too big for a 32-bit-system.)

I use my own siever, along with some of the CWI tools and some of my own
for post processing. I can only run at night so I use the Windows
task-scheduler. I run from a central server over a wide-area net
(multiple buildings miles apart). If the server or net has a glitch, my
jobs stop. If someone disconnects a machine or turns it off, my job
on that machine does not run... I have a total of 15 machines; 2
are fulltime, the rest half-time.

Default Thanks for the insight

I'd like to thank everyone who responded to this poll. I've got some ideas percolating in regards to implementing something a little more robust than the .pl scripts for network-aware jobs (local at least....) Whether or not anything comes to fruition is another matter, it all depends on my free time this coming year....

I'm thinking something more along the lines of NFSNET to allow adding or dropping machines while a job is processing.....
