What do you mean by "a local problem?" Could you be more specific?

Looks like a false alarm. Symantec needs to fix this. There is no virus or any other malware in Rosetta's executable.

But I don't know, whether Rosetta restores the application automatically, once the servers are back online, or whether you have to reset the project.

I had to stop Rosetta as well. My two working rigs (3.4 GB each) got unusable and even my gaming rig (12 GB) was having memory issues.

Still 1.8 GB per task is just ridiculous. I moved over to POEM.

Send me an email, once this has been fixed and I might return...

Live long and prosper,

What are your settings?
Because if you set your "allowed RAM usage" by BOINC too low, then you'll have WUs waiting for memory irregardless of how much RAM you actually have installed.


memory usage (idle and load): 95%
swap file usage to 90%.

When a core goes idle due to "waiting for memory", BOINC will fire up another thread and run it as long as it can. It may run in less memory, or perhaps by the time it requires more, one of the other tasks has released sufficient memory. Either way, a larger list of tasks to be processing improves your odds that no cores go idle.


This is simply not true. There was and still is a sufficent number of WUs available, but no new task is started when a task is automatically suspended and waits for memory. The only way to start another task is to manually suspend the tasks that are waiting for memory (as of BOINC 6.10.56).

It's turning nasty... On my 'big' computer, I had two tasks 'waiting for memory', thus two cores idling. As I assumed before, 1 GB per core is no longer enough.

Of course they won't change the system requirements page. These are the minimum requirements, not the recommended or optimum ones.

I'm just wondering, what happens, if somebody with only 512 MB of RAM gets on of those 1.8 GB tasks, I've seen?

Hello Chris,

these are just my observations. And as well it's a 'worst case' scenario. But since there are WUs utilizing 1.5 GB of RAM, one could end up running only these WUs.
I already ran out of Memory on my two 32-bit Systems, resulting in idling cores. I never ran out of memory with 2.14 tasks...

Currently, there are 4 WUs on my 6 + 6 core machine, each utilizing 1.3 to 1.5 GB. And another two are utilizing 670 MB and 850 MB respectively. The overall memory utilization is already at 88% of the available 12 GB RAM.

This one crashed yesterday after 40 minutes:
T0528_t4_rs_stg0_lrlxjcst_t000__casp9_SAVE_ALL_OUT_22246_78_0

When it crashed the memory consumption was 1.5 GB. The message says 'Directory not found'.

Switch to 64-bit! =]


I can't. That one is my computer at the office and I installed XP 64 in the first place, after assembling this computer. But some applications didn't run properly, so I had to revert to 32 bit.

None of my 3 computers is actually up to tasks using 1.5 GB of RAM. Even my 12 cores machine has 'only' 12 GB of RAM, which is at this point already 4 GB short.

The new memory requirements for Rosetta are:
2 cores: 3 GB
4 cores: 6 GB
6 cores: 8 GB
8 cores: 12 GB
12 cores: 16 GB

:/

The highest I've seen so far is as well 1.5 GB for a single WU.

This is giving me a headache too. Due to the 32-bit OS, I only got 3.4 GB of RAM available on my 4 + 4 core i7. It was already close to the edge with the 2.14's 500 to 600 MB WUs...

At the very moment, I'm typing this, one of the 1.5 GB tasks crashed... I'll post details in the appropriate thread tomorrow.

If you look at his computer list, there are 38 copies of one computer. Looking at the one with the most tasks, they all crashed, because of an access violation.

I would run some system diagnostics. Looks like the RAM or CPU might be faulty. Or it's a driver issue... Hard to tell from the distance.
13) Message boards : Number crunching : WUs running with priority for unknown reason? (Message 67623)
Posted 7 Sep 2010 by Jochen
Post:
This happened, because you had this long running modell. It was running double of the estimated time. The BOINC manager will apply that running time to all other Rosetta WUs. So your cache doubled (6 hours instead of 3 hours per WU). So you were probably facing some deadline problems and therefor the BOINC manager started running Rosetta tasks with high priority. A couple of WUs later the estimated running time dropped to 3 hours again and this solved the problem.

Thanks, Jochen. It was interesting to re-read the Rosetta license agreement.

I didn't link to the license agreement, but to the Rules and Policies.
Scroll down to the bottom of the page and read the disclaimer. At least there is one in the German translation of that page. In bold letters...

deesy, read this: http://boinc.bakerlab.org/rosetta/info.php
Rosetta never promised to keep your computers busy. And they never will.
Any further questions?

How do you know, there is a problem? The limited number of WUs could as well be a side-effect of an update (software or hardware). We simply don't know.

I have received no new work units in the past 36 hours or so. I have rebooted my machine, and I even shut it down last night. Still no work units, even though the "Server Status" page indicates that all servers are up and running. So ,,, what's wrong?

There's nothing wrong and absolutely nothing you could do. Rosetta just generates only a limited number of WUs right now.

You could try one of these old pagan sacrificial offerings, I've read about in one of the other posts... ;)
