So, is there any noticeable benefit of 1.52 over 1.39 on BRP4G?
HD 7750: No improvement
GTX 750: Run times seem good but I don't have any old data to compare. A quick test indicates 1.39 would take about 15% more time
BRP4 and BRP4G is actually the same data (Arecibo), the post-processing doesn't distinguish whether a task ran on GPUs or CPUs, and so doesn't the progress counter.
Ah ok, thanks for the info.

My Titan Black (on PCIe 3.0 x4 only) went from ~2.200s per task (1.39) to ~1.100s per task (1.52).
Three GTX 750 Ti (PCIe 3.0 x8, PCIe 3.0 x4, PCIe 2.0 x4) went from ~3.200s - 4.200s (1.39) to ~2.400s - ~2.800s.
(one tasks per GPU, one GTX 750 Ti clocks ~100 MHz slower than the others; all GPUs are in a single computer and the integrated Intel HD4600 is also processing Einstein tasks!)
So yes, the benefit is huge in my case!! Thank you! :D

My GTX 750Ti cards have sped up by a few minutes with the new app. Comes to around 14% improvement.

BRP4G change v1.39 -> v1.52 Beta; Total Time (CPU time)
NVIDIA Tesla K20c: 1900 (500) -> 1400 (300)
AMD Radeon R9 280X: 1650 (900) -> 1150 (600)
So a significant improvement! Let's roll it out into production ;-)

Validation statistics look surprisingly bad for a few app versions (e.g. Linux 64 ATI). I'll leave it at Beta until we have collected a bit more data.

There is a Beta version of a CUDA 5.5 BRP6 app for 64Bit Linux. This is mainly meant to test the build and deployment process for CUDA 5.5.

I can not seem to start these, they error out for me immediately. vanilla BRP6 crunches fine.
Running 2 gtx-460 gpus, each running x2.

Thanks for testing. That was a problem in deployment and should be fixed in the new version 1.54.

Thanks Bernt, that has solved the problem, the first two 1.54 completed uneventfully (yet to verify).
A little early to make any comments on performance.
