Re: For Current Volunteers: Advance Information on Our Newest Project

At least 6-7 years ago, noting that 're-reading' does not effectuate all flags of the cc_config part of the options section i.e. at times a client restart is still needed.

Re: For Current Volunteers: Advance Information on Our Newest Project

Minimum CPU Requirements

What are the minimum H/W requirements for this project in terms of CPU?

After earning 8 years crunching for the OPP, I decided to use both my laptop and desktop to get my one year status for this project.

My laptop has an i7-3740QM running @ 2.7 CPU. Actual speed is 1.89 according to Task Manager. Even when I run the laptop 24/7 there is not enough time to finish the WUs before deadline. Unfortunately I end up deleting WUs as they are not completed within deadline. What a waste!!!

My desktop has an i7-8700K liquid cooled CPU running @ 4.20 is fast enough to finish WUs within deadline.

May I suggest that recommended CPUs be posted in the recommended h/w section besides the s/w.

I am not doubting you on what you say, but i find it incongruous that an I7-3740QM can not finish an ARP unit in 7 days. Since it is a laptop, I suspect it is throttling itself due to heat issues, if it is running as slow as you say it is. I have a desktop I7-3770 which takes about 24 hours to finish an ARP unit. Your processor shows a Passmark score of 5647 while the I7-3770 shows a Passmark score of 6371, a little bit faster but not too much. I would think an ARP unit would take something around the 30 to 32 hour mark. Just one more question: How many are running at a one time ?
Edit: Are you running with or without hyperthreading ?

Re: For Current Volunteers: Advance Information on Our Newest Project

Ah Sgt Joe, we "meet" again online.

To answer your question, I am using hyperthreading. The CPU works on 8 WUs at the same time.

I also have the laptop sitting on a twin fan cooling pad. According to HWMonitor s/w, CPU temperatures range between 83 degrees C - 88 degrees C.

The OS is fully patched Windows 10.

I look f/d to your suggestions.

You say you work on 8 units at a time, but are they all ARP? You should not use more than 4 of the 8 on ARP. Use the other 4 on something else.

ARP has a deadline of 7 days, normally, but re-sends are only allowed 3.5 days. Recently, there have been a lot of stragglers being crunched which have also been allowed only 3.5 days. Has that been the problem?

I would agree with Sgt. Joe about the machine speed because my i7-3770 hyperthreaded runs 4 ARP, 3 MCM and 1 OPN at a time and the ARPs finish in about 24 hours.

I use WIN7.

This makes complete sense. If you run 8 at a time you risk escalating cache misses which would tend to bog down your system. You would do well to mix with other work units. let us know if that helps.

Re: For Current Volunteers: Advance Information on Our Newest Project

I just started processing the ARP files and I find the "Elapsed Time" to be completely wrong. I'm running a total of 8 processes but only 2 at a time are ARP. Since the deadline for one of them is early morning july 24, I let the computer run over night, so the computer worked on both of them from about 2 in the afternoon until 8:45 this morning when I had to shut down for a few hours. After continuing on at about 10:30 a.m. I just noticed that the "Elapsed Time" for one process is 3 hours & 29 minutes, and for the other it is 1 hour & 50 minutes. The other 6 tasks, mostly Mapping Cancer Markers, are processing normally. I seem to be wasting my time with ARP, not to mention the time of the ARP project which would benefit from faster throuhput. I'm running on a Windows 10 desktop, Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz, 3600 Mhz, 4 Core(s), 8 Logical Processor(s).

I guess my main question is, why is the "Elapsed Time" only about 1/10 of actual time?

ARP checkpoints once every 12.5% of progress so checkpoints can be hours apart and a reboot will cause it to lose all work since the last checkpoint. The solution is to suspend or hibernate your PC or to choose other projects instead of ARP.

Re: For Current Volunteers: Advance Information on Our Newest Project

Stating CPU time as well as elapsed time might have helped. I suspect that for some reason your machine is shutting down and restarting of its own. Checking the event log would have helped to see what is happening.

Your machine is 4 generations newer than my i7-3770. I find mine takes about 3 hours for each checkpoint which is every 12.5% as Falconet has said.

I would suggest that you check the 'Properties' of your ARP units when they reach each 12.5% (let it go slightly past the point) to see what the elapsed and CPU times are. If you leave it to run overnight and you still have a problem, check the event log to see if it has restarted at some time.

Otherwise, it is possible that your settings are too restrictive for ARP.
