X-Mailer: VM 6.75 under 20.4 "Emerald" XEmacs Lucid Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG We have an application which is precompiled, for linux, and stupid. It uses (at times large) scratch files. We want to run this on our diskless machines (CPU farm) to cut the per-cpu cost of the computation ($200/drive starts getting significant at a few hundred machines).
