Re: tasks with 8 GB memory requirements

I've got 6 monsters out of 40 tasks running now and 36GB out of 96 GB being used. No issues at this ratio of monsters/standard ecm tasks.

Re: tasks with 8 GB memory requirements

I now see tasks in my que with names ending in P2_0. Are these RAM Monster tasks?

It'll take a couple of hours or so before they start loading into my processors.

My boinc manager settings are 100% CPU (40 threads), 90% RAM and 25% swap file. OS is linux mint 19.

Re: tasks with 8 GB memory requirements

The host ID is 437331. On that computer, I aborted all ecm tasks but could not get work on another subproject so I moved that machine on to another project.

Re: tasks with 8 GB memory requirements

Apparently, I had a worse case scenario for my machine. I was working on ecm tasks exclusively and the RAM monster wus started downloading and they had the shortest deadline so eventually all my cores were loaded up with 100% monster wus. These tasks grabbed all available RAM and swap file space as ...

Re: tasks with 8 GB memory requirements

These ECM tasks are running with -maxmem 10000. Is this 10000 MB/10GB?

Is this a mistake? Should I abort these WUs with _np_ in the task name?

tasks with 8 GB memory requirements

There are tasks with _np_ in the name with extremely large RAM requirements (~8 GB) such as this one: ecm_uc_1535071917 _np_ 161_2900e6_01_289_P2. My 40 thread Xeon processor with 96 GB RAM has been swamped with these WU so I have to reduce CPU% in boinc to 25% just to get through these WUs and even...
