Unfinished tasks have no timings, so will await when they become finished :)

Yeah, just did clickable links so you can check often - these tasks are on Main, so subject to 24-hour purge (assuming validation ;D).

Note: I do have one work unit that started crunching with the v4.35 optimized app before I switched to the v4.37 optimized app.
It had approximately two hours on v4.35 app and approximately eight hours on v4.37 app (it was about 33% complete) before it ended with Found 30 single pulses and 30 repeating pulses, exiting message. I don't know how useful it will be, but here's a link to it anyway: Task details.
The work unit done with only the v4.37 optimized app will complete approximately 23 hours from this post (27.1% complete).
Jason G:
Version 4.37 contains some radar blanking related overhead. You'll notice also in the stderr.txt that SPLIT_COMPLEX is enabled in 4.37, but not in newer builds. V5 showed it to be faster without that, and also has an improved filter that lab tests showed little/no improvement, but yielded a nice speedup over previous builds.
Given the lifespan of 4.37 is going to be a total of a couple of days, I wouldn't worry about that edition too much, especially considering it wasn't meant for release, only to pad the transition of code-base, which happened to be useful (it seems by accident) for hoisting checkpoints up a notch [Well less that, than squeezing out a few obscure bugs].

LoL :) Now AstroPulse will attract credit likers until the point of boykott for too big credits for hour :)
It's clear that state of optimization in MB build higher, but credit is lower.... Good reason to blame that credit system again :)

Woohoo! Cruiser has finished its first v5.00 work unit at Beta!
Task details.
Credits (868.56) divided by CPU seconds (94123.61) = 0.009227865 credits per CPU second.
Other work units on Cruiser:
Shorty Multibeam - AK_v8_win_SSE3 app - Credits (16.84) divided by CPU seconds (2264.34) = 0.007037046 credits per CPU second.
Average Multibeam - AK_v8_win_SSE3 app - Credits (44.12) divided by CPU seconds (5268.02) = 0.008375063 credits per CPU second.
Once again confirming that AMD's Phenom efficiency is very low in comparison to Intel's Core 2 efficiency for SETI@home work units.
