Problem : When I start BOINC client (with default settings ) on my machine and add Rosetta@Home (with default preferences) to utilize my CPU but after some period of time OS gets hanged and does not work properly until I detach from Rosett@Home. And I run into one more problem, that is BOINC running with Rosetta@Home causes to hang only particular application, in my case Gtalk and VS 2010. When I detach from project its works fine. Is there any problem with Rosetta@Home or BOINC client?.


Settings:
Windows 7 64bit Home basic
Intel Core i3-2100 @ 3.10 GHz
4 GB RAM
Boinc 7.0.64 (x64)

You may be running low on memory depending on what tasks are currently running and your settings. I am guessing your computer is the first one listed? Is this it?

Hi rajesh

I don't know of any conflict between R@H and any particular applications and I use Gtalk occasionally.

On my i3 (which is a generation older than yours) I have found that 3 tasks run better than 4 (because the loss of one virtual/hyperthreaded core is more than compensated by the increase in L3 cache available per core). That might also help with your issue if it's a resources problem.

Hi,

Thanks for reply.

I have changed global preferences as follows, and it works fine for me means when I am doing something on my machine then BOINC client immediately stops R@H execution as well as remove apps from memory and if I go idle for 0.30 minutes then it immediately start R@H. Transitions (running <==> suspend) are also smooth nothing gets hampered.

Is this solution fine or someone has better than this?

Hi

If you set
<leave_apps_in_memory>0</leave_apps_in_memory>
to 0 then rosetta will lose any work since the last checkpoint which might be some time ago. Setting it to 1 will mean that it takes time (should be a couple of seconds at most) to put the information out to the page-file though, so it depends on your priorities. If you have a slow hard drive then could you move the BOINCData folder to a quick flash drive?

<max_ncpus_pct>0.000000</max_ncpus_pct>
I recommend setting this as 75% - I think you'll get more credit (and more rosetta work done) and it will reduce the effect of any paging etc required as less RAM will be in use for the three tasks.

HTH
