The requirements for this project are a joke! I am running a quite expensive Laptop Lenovo with i7-8665U. Those projects require around 24 hours to complete on 100% CPU usage per core and they give me 3 days to complete! So I need to literally dedicate a pretty decent device to almost non stop use 100% cpu power per core to perform the task in a normal time. Most project give me around 7-10 days deadline and they take only 3 hours to be calculated. Also most people use their devices while donating CPU power so they obviously don't run 24/7 and they leave the devices powered off. Why such a harder project gives so little time? Sorry Africa but I am unsubscribing.

MomchilAndonov,
the project requirements are not a joke and they are clearly defined and communicated.
Some projects have short WU running time and often checkpoints.
ARP1 has only few checkpoints and each WU takes between 15 and 30 hours on my machines (not the fastest one).
On my side, I do not run WCG projects on laptops, only on desktops.
Additionally for ARP1 the needed data transfer in both directions (download, upload) is significant. Until 2 weeks ago, I had only 5 Mbit/s down and about 1 Mbit/s up. Upload of a computed ARP1 WU took about 20 minutes. Luckily I have now fibre and ARP1 WU upload takes now less than 20 sec.
Since other projects with more limited requirements are available on WCG, I do not see the problem with ARP1, excepted that the available work is relatively limited.
Happy crunching,
Yves

My recent average went up by about an hour. There's always been excursions, in my case to 27-28 hours from normal 20-22. CPU speed is constant.

Abort? A task that makes periodic progress is fine. Someone posted how many minutes of weather simulation the percentage is incremented. Mine go up by 0.021% every so many seconds, so guess its 1/4800th of 48 hours or 0.6 minutes per percentage increment, every 36 seconds of weather in quasi fast forward, but that's like just over 2 on my machine.

what I meant was that I had a bunch of WUs due on the 23rd morning. They just started, my time, would be less than 12-18 hours, which means it is impossible that the WU will finish before the deadline to submit the project. I always hate that the WUs are due in such a short time, I have to calculate carefully if I can finish all the WUs that are running. Daytime I do 16 nighttime I only do 8 due to AC and high temps in the summer. So it is a little difficult. so yes, I had to abort several WUs as they were not going to finish by the deadline. One of them was already in 7 hours. I aborted it because there was no way it was going to finish.
