	We are testing the new applications for Windows and Linux. They should be out tomorrow. The are very many added features from the science point of view. From a practical point of view the multiplier will pass from 1.5x to 2.0x for everybody (SETI 2.4x). We will give further 25% for results returned within two days. Speed should be the same. gdf

	The applications are ready and tested. We are waiting tomorrow, as today we are submitting several updated WUs. If we change two things, we would not know what's wrong in case of problems. Best, gdf

	I assume that the new apps will d/l automatically?

	I assume that the new apps will d/l automatically? Yes, they will ... I already have two 6.63 tasks on my queue ... I should be starting them in about 4-6 hours ... I hope they don't error out

I hope they don't error out I managed to complete my first 6.63 task here. The timestep is quite high though. I might try the new Boinc version and see how it copes. Rob

	I completed my first and the T/S was about the same ... the run time slightly higher. The 4 in work should start pumping out in the next couple hours, the next in line looks to be 8:12 which is about 2 hours longer than before. So, I will have to look to see what is up with that if it is an outlier or just a longer running task ... More to come I am sure ...

	We have performed a further application update to fix one bug which did not allow us to run the new type of workunits. gdf

It says the application (note: hardest page to find!) was applied at 6pm so any prepared after then I guess. Should I cancel the 6.63 in my queue? Edit: Just did and received a 6.64. Rob

	you don't need to cancel old WUs, these are just fine. We need the new application for the WUs which we will submit tomorrow. gdf

	It is a rather technical but important change, from now on we will be able to use the Amber force fields, which is more accurate for certain applications. gdf

And all this time I was hoping that we would start using the puce force fields ... For those mathematically inclined: AMBER force Fields (an acronym for Assisted Model Building and Energy Refinement)...

	I observe that the 6.64 application runs 4x as long on a seemingly same type of workunit, is that intentional ? It also uses 0.25% CPU time instead of 0.15% with version 6.63. The GPU is much cooler. My impression is that this is not as efficient as before...

The GPU is much cooler. My impression is that this is not as efficient as before... My first 6.64 started running a little while ago. I am not noticing any difference in elapsed time or GPU temp so far, but I am seeing the CPU utilization going up to 25% from 15%, same as you. My hardware is a Q6600/GTX280(FOC). Your CPU is faster and our GPUs are similar in speed. I'm not sure what conclusions to draw from this. I find it very interesting and somewhat perplexing that BOTH of us saw 15% CPU utilization under 6.63 and 25% utilization under 6.64, despite having GPUs that run around the same speed (and hence should require the same amount of servicing by the CPU), yet your CPU is faster. EDIT: I just noticed that I have queued up a work unit that looks very different than prior work units. I guess this work unit is one of the new ones just released today. Of note is that the estimated run time is double that of the older tasks. I suspect what you're seeing is also one of the new ones, and perhaps they're just bigger.

	I bet you are also using BOINC version 6.6.20 ? I just read another thread and decided to test it. I got rid of BOINC 6.6.20 and reinstalled 6.4.7 and bingo, I am back to my old high speed crunching !

	Yes, I've been using 6.6.20 for a while. It seems to work fine when you only have one GPU, and solves some problems I had with 6.4.7, most notably the failure to keep all CPU cores busy. P.S. Check the edit I made to my previous post.

	Hi, I read your edit. I suspected a change in workunit structure at first too, but I can conclude that BOINC is the real cause of the issue. The same workunit I was working on before and which I paused, crunches 4x as fast with BOINC 6.4.7. on the GPU. (edit) I can also notice by the GPU temperature, it shot up by 10 degrees after going back to BOINC 6.4.7. It is much more efficient.

	The 6.4.x series needs manual tuning to get it to properly feed all GPUs, 6.5.0 does not need this manual tuning. See the other threads for my comments on 6.6.20, .23 and .24

Of note is that the estimated run time is double that of the older tasks. I suspect what you're seeing is also one of the new ones, and perhaps they're just bigger. As it turns out, that new work unit is now running, and despite having an initial estimate that was much higher, it seems to be running in the same time as the older work units. GPU temperature is normal, and, oddly enough, CPU usage for this task is back down to 15%. Mike

	Hi! I use 32 bit OS and crunch gpugrid :) Do you have also 64 bit version of your aplication? I mean real 64 bit, no 32bit runing on 64 bit os. If you have 64 bit is it faster then 32? I don't know if it is time to upgrade to 64 bit os. My comp have 4 gb ram, on XP 32 bit I have 3400Mb witch is ok ... ____________ POLISH NATIONAL TEAM - Join! Crunch! Win!

Since there is little time spent on the CPU, changing the application to 64-bit won't make much difference. Projects where that can help include Prime Grid, ABC and at least one other and my mind whet blank. Oh MW with the optimized applications.
