Yes, there is a more recent version -- BTime v1.1 has an improved algorithm which delivers more robust performance. This currently works for BProc clusters, and it worked for regular Linux clusters until about mid-December, when the system call table in the kernel became read-only which broke my kernel module. I'll soon have another way of getting detailed timekeeping info from the kernel, but until then, BTime v1.0 may be a way to get started.

FYI -- BTime v1.1 is finally available, as of 2006-05-15. It uses an improved filtering algorithm and a kernel module to read low level kernel timekeeping variables.

Hi-
We're going to give btime a spin at Livermore on our CHAOS clusters. I've grabbed the latest drop from SF. Is there anything more recent?
Thanks,
