What is the number of simultaneous task people run on this project? I see its heavy on Ram and disk space but our modern PC's should handle it, especially with SSD and DDR4. Default Seems to be 1 but wondering what other people run to maximise our efforts
Desktop 1 - Ryzen 9 7950x, RTX 4070ti, 64GB DDR5 6000,
Desktop 2 - Ryzen 7 5700x, RTX 3060ti, 16gb DDR4-3200,
Laptop - Ryzen 7 4800H, GTX 1660ti, 16gb DDR4-3200
SFF Dell - i7 8700, RX 6400, 16GB DDR4,
SFF Dell - i7 7700, Tesla P4, 16GB DDR4,
SFF Dell - i5 7500, GT 1030, 16GB DDR4
SFF HP - i7 3770, GTX 1650, 16GB RAM
Micro PC - N100, 12GB 4800mhz Ram

Greetings turbo0

Well on my 8 thread systems, I would only run 4 at a time, was running a mix of SCC and FAH2, which worked in getting a constant feed of workunits, but I haven't done ARP for about 2 months (wow has it been that long), as I was at max cores on COVID19 workunits, with the occasional TB workunits.

Others may have a nore recent update, on how they are progressing.

Cheers

I had all my cores crunching ARP last week. Yes it's a bit of memory hog and the tasks take over 1 day to complete. I'm not sure what the difference in times are if I only ran say half the amount of wu's.
I did notice my GPU work slowed down though. Whether that's from memory or just too many core running (even though I reserve 2 cores for a GPU work unit) My GPU work is running much better now that I'm onto Primegrid.

I'd just got flat out if you're chasing a badge. Takes forever though. Credits aren't great for ARP.

Hey everyone.
I know this is a bit of an older thread and it is not mentioned here but if you go into device profiles (settings --> device manager --> device profiles) you are able to create a custom profile which lets you change the project limits (maximum number of tasks). It took me a while to find it so perhaps someone else is yet to find it.

Thanks
Ben

Any information is helpful!
Thanks Ben  :thumbsup:

Am crunching COVID and ARP together and i get one ARP wu per machine and the rest COVID makes for a long crawl on getting anywhere on ARP.

How long does one WU run for? I am sure that these took 12 hours each on ubuntu, I've swapped over to windows for a bit and I've got a work unit that is estimated at 18 hours. Anyone else have observations on length? Maybe the estimate is just out?

I did a bunch recently on Linux and they took between 22 and 24 hours to complete.  I did run one per core which most probably slowed them down though.

I just looked at one of the tasks and my buddy on that task took almost 33 hours so it depends on the machine.

I just checked my stats in ARP and on my Windows box I'm taking approx 25 to 28 hours per task. Occasionally there is a long 30+ hour task.

Thanks, guys. They are certainly quite different from the other subprojects!

chooka03

Yes, ARP take a LONG time. I thought from memory it was over 12 hrs for each task on my 3950X.
Also, if I ran all 32 tasks at once, it almost locks up the system. I think they use a lot of RAM as well. I know it screwed with my BOINCTASKS.

Greetings All

Yes they do run a long time now, but also there is more info on ARP forums over at WCG, but 1 thing I did pick up, only run what your cpu has in real cores

So if you have a 4c/8t cpu, only run a max of 4, if you have a 8c/16, only run a max of 8 and well you get the picture, as long as you have the memory as well.

More reading over at the ARP forum on WCG.

Cheers

There certainly is a lot of reading over there. I tried looking over there, so many pages of info but I couldn't find anything comparing the run times for the same computer between different operating systems. But take this as a public team service announcement, try running Linux if you want quicker ARP tasks (although the badges are time-based so if you are looking for badges it makes no difference).
