Well, sadly this is unacceptable on my machine (1024MB RAM, 1.7Ghz processor), maybe I have too many other things running for UD to work successfully at the same time, but they take precedence so I'll be opting out of Cancer at this point. I suggest you look again at the RAM usage and minimum recommendations

Hello Nigel,

If you want to limit the amount of memory that the WCG application is using, you can try setting the percentage that the application uses in your Device Profiles, the "Use no more than: __% of total memory." If you are not using BOINC, try running it instead of the UD agent.

Hello Sek,

Now I know, thanks for the info. By the way, this line is in my global_prefs.xml file:

<ram_max_used_busy_pct>95.0</ram_max_used_busy_pct>
<ram_max_used_idle_pct>95.0</ram_max_used_idle_pct>

I wonder if this has something to do with memory throttling. I'm using 5.4.11.

Cio, those 2 lines are leftovers from when u installed the 5.8 test versions. Likely u entered them at some other project where they have advanced also in preparation of the final release or these values were amended manually in xml file. The install defaults are 50/90. WCG set for the idle one 100%, but that may change as 100% was done not to handicap the advanced 'testers'.

The 50 percent 'busy' default put HDC projects in a 'waiting for memory' state on my 1.5gb machine, so upped it to 60%, which was just enough to tilt it, yet keep enough for me to work..... the 'idle' of 90% I left.

Halfcard, yes 1025 for UD agent effectively put the ram mark at 1280 or 1536 physical ram as 1025 to my knowledge does not exist. Why, well occasionally I've seen peaks happening of models being *1090mb*..... the swapping just kills a machine as a usable computer. And that was on BOINC, which does not have all this un-throttled overhead.

DD-865,

If you migrate to BOINC you can again run HDC and much smoother than UD. There the requirement is still 725mb RAM.

cheers
