restarting of the client appears necessary on *nix to have BOINC Manager display the CPU count correctly, but that's just cosmetic it appears.

I simply changed the parameters and used BOINC Manager, Advanced, re-read config - no restart needed. It read it, suspended the other jobs, relaunched an existing job with -t N.

Everything looks good from here as well. So far 4 machines with WUs that have validated which includes a mix of win and lin across i7s and 1 old phenom II X6. No errors and no invalids.

I am looking forward to getting a crack at badges for this one.

ESP LLR should be up to silver before long. Other than ESP and the 321 sieve, amethyst+ for everything available when I joined.

There is discussion of the PSP sieve re-opening for ESP - this predates me entirely. Bring it! (AP26 alas ;))

Two projects to bring up to amethyst and then several to go to ruby. It is hard to not jump the gun prior to challenges such as the upcoming 3day SR5.

I have to admit the badges are addictive, even when I'm trying to hold positions in 2 other [CPU only] projects.

Could we stop treating AMD chips 2nd class to Intel for FMA and AVX[2]/xop ops? 2 x Opteron 6348 (2 sockets empty right now) @ 12 ALUs/6 FPUs (yes I grok the FPU usage of LLR). In some cases the AMD side of the house got the instructions before the Intel side, yet the BOINC apps couldn't care less about AMD. This home setup is mirroring a work setup (well 2 CPUs instead of 4 as I haven't won the lottery) and the ALU core count for maximizing virtualization in our workloads grinds Intel options out of the running on U/socket/core/perf. (Edge cases where 48+ ALUs in a single box as a predominant workload really mean Intel is the 2nd class citizen). In the interim: could the actual source of the boinc apps be readily available in *some* version control system so we can build our own (-mcpu=native -mtune=native] on say gcc 4.[78].x. Even some of the generic c non-optimized code on the newer gcc releases targeting a given cpu/arch is leaps and bounds ahead of the available "stable" app unless you are Intel only.

Lennart,

Thank you for all the work and time you put into this project! It can be a rewarding experience but can really take its toll. Be sure to give yourself justly deserved breaks and rest to help prevent burn out. I do not want to think of PG without you!

--

I am one of the *two* admins for DistrRTgen (freerainbowtables). When I joke that the project is my 2nd job, it literally takes all the time I can give it outside of my day job. Having to balance running a server, boinc, the project, responding to users, keeping up communication, finding time to improve or fix code, etc. means a lot of work for two people to somehow manage.

To others that are pecking at Lennart as if he had abundant free time that he was just wasting instead of answering every post with all details desired, shame on you! The time demands from such work are extreme and burn out is always something very close for many trying to juggle all the roles as best they can. Yes, abundant open communication from project staff and crunchers is vital *but* please realize time spent on a task such as message board responses is time taken away from other areas.

I just wonder....: Where is the work??? ;-p

Ive been waiting for over an hour.. And run something else instead..
since PG dont want to give me anything.. lol - Zumezthing`s Not right ;-)


I've been constantly getting work. Maybe you should give your settings a quick look just to make sure.


It seemed mostly to be totally random. It took me 4 hours to get work to all my machines and I'm not even going to discuss *keeping them with work*.

Maybe you are just plain lucky, or have few machines, or have few machines with > 4 real cpu cores.

2^4 obviously

Computers are base 2 (a bit is 0 or 1) and not even quantum computing has more than 3 states per qubit (0, 1, or superposition).

Hehe, yes I have some that will be about 5 mins late.

Well, cleanup is still running for the last challenge so maybe we'll get final 2011 results next summer?

sub-title: over-clocking gone wrong :D
