BOINC Pentathlon 2013

An annual event sponsored by SETI.Germany where all BOINC-Teams are invited to participate. This competition is inspired by the Pentathlon of the ancient world. Just like in ancient Greece teams perform this BOINC Pentathlon by running 5 different disciplines. This means within 2 weeks the participants will need to crunch 5 different projects, each for 5 days.

Funny how we all have different ideas on this. I only run CEP2 on regular drives because of the enormous amount of read/writes that would shorten the life of an SSD. :shock:

I'm running 26 of them now, all on SSD's. I up the task checkpoint way up so it doesn't write to them very much (I use 5-10mins). Also they are almost all Intel SSDs with a nice warranty backing them up. So I'm not worried about it. :icon_cheesygrin: And really its only for a week or so, doubt that would damage them anyway.

32 GB of read/writes per WU.

I wonder how a Raid 0 would handle CEP2?

Then everything's cool for 3 or 4 more days and then the same thing. Many crunchers have commented on error code 195 in the forums, but no solution. Anyway, I'm almost up to 1 year for CEP2. Have my PC set for a max of two of these at a time.

I really dislike that they chose CEP2 for the Pentathlon. I had gotten to 2 years and stopped crunching it due to problems.


Hear hear...
I've seen that message blamed on "not enough memory" and a failure of BOINC handing off to CEP2. Sorry I'm no help...Does it do it at the beginning or are you losing processing time?

PS I'm only running 1 WU at a time haven't seen the error yet..But I'm only running it on my newer systems.


If a CEP2 WU is going to error out, it always does it at the beginning -- 0.03 hours maximum. If it goes past this time, it never errors out and always goes to completion. Strange --

Crazy is right. That's why I don't run it on SSDs

After seeing your post I went and got some SSD tools. I let them run overnight and it went through 300GB+ of writes in just 12 hours according to SSDLife and CrystalDiskInfo says I've written 6.33Terabytes over its total life. On the bright side, neither Intel SSD I'm tracking dropped in expected life at all. It still says its expected/estimated life span is another 8 years 3 months and 29 days (its reads data off of the SMART chip--reads/writes/cycles/etc)). I am only running them until I get my two year badge then I am definitely stopping. SSDs get faster every year but I still want to get at least another 3 years out of it. Thanks for the heads up! On a side note, I did see in a couple of places comparing HDD to SSD for this project, HDDs cause CEP2 to take longer because they can't handle all the I/O, given that's only if you run more than one or two.

HDDs handle this project fine if you change the default disk checkpoint setting in BoincManager from 60 seconds to 300.
