I have lowered my ffa_block and -ffa_block_fetch to what I had before on AP v6.

Those that fix the problem in your host too? Just curiosity.


Well, I haven't had any 30/30 tasks yet after that, and those are the only WU's that shows this problem. (Like Raistmer says)
http://setiathome.berkeley.edu/forum_thread.php?id=75863&postid=1590653#1590653

With the below settings as I run now, the WU's runs a bit slower, but I rather take that, than the memory hogging.

-unroll 16 -oclFFT_plan 256 16 256 -ffa_block 8192 -ffa_block_fetch 4096 -tune 1 64 4 1 -tune 2 64 4 1 -instances_per_device 2

Hm... Looks like no matter if I write in English or in Russian... nobody cares to read anyway :/

No need to invent new entities w/o need.


I read that, and pointed out to Mike in a PM that it is probably the problem, as you stated.

I have lowered my ffa_block and -ffa_block_fetch to what I had before on AP v6.
I may go up to unroll 16 though, from my initial 12 which I am back on now.

Try to use a smaller -ffa_block and you will see, the memory hogging WU will use a lot less memory (i like the name)


I'll drop back to my original (since v6) ffa_block and -ffa_block_fetch, as well as my unroll.


Unroll will be bigger then.
Watch out.


Hmm, is unroll 12 bigger than 16? Am I missing something here? Is it backwards?


I meant if you remove unroll in comand line.


OK, a simple misunderstanding,

Interesting, Sten-Arne uses ATI, not NV like me, so aparently the problem is in the code itself and sure not host related.


It is since i dont get this high memory usage even with biggest unroll and ffa_fetch values.
Same on my sons 7850.


Could this be memory related? This old computer only have slow DDR2 memory, single channel.

OK, I spoke to soon. Now I also have one of those memory hogging WU's.

Virtual memory size 1 526,04 MB
Working set size 1 416,16 MB

Running extremely slow, but does progress. Badly slowing down the other running task too.


This is the task:

ap_10jn14aa_B2_P0_00382_20141022_13024.wu_0

Edit: This never happened before I introduced these new timing switches. Not before I got specifically the -oclFFT_plan 256 16 256 to take effect. The computer run all day with the new timings, except for the oclFFT_plan, and this never happened.

It will finish though what it seems, only very much slower than normally. That WU will take just over one hour it seems.

However, what will happen if I get two of those running at the same time, is another question. The computer may run out of memory, since it only have 4 Gig.

OK, final Edit/Adding: It ended early, it was a 30/30 WU:

-oclFFT_plan is case sensitive.

Maybe is a good ideia change that, all the other switches uses lower case letters.


Like Raistmer said its for advanced users.
Everybody can snip it out of the read me.

Sorry for the typo.

My mistake.


Bah, advanced users, and crazy people like me :-)
The speed up, is incredible. It's even better than what I wrote in that PM to you.

The WU production increase, is almost as high as if I had bought another card.

Geeze...

Erm.. That date has already passed Celt....
It's now 24 Oct 2014, 4:08:00

I vote for "Rose" from WinterKnight even though it managed to avoid the list too. :-)

I object, even though it is a fun objection. After all this is supposed to be a fun contest, but nevertheless, I object in a fun way :-)

Why?


Because it is fun to object :-) (The devils advocate?)

Can we vote early and often, or can we only vote early and once? :-)


My very strange intellect (What there is of it.) wants me to
say 'Yes' and then end it there. All votes will be counted,
there are no restrictions on the numbers of votes a person
can cast for different names. Block voting will be discounted.
i.e. "I vote 37 votes for XXX-butt." I am hoping that some
sort of plurality will be achieved. Even if every one just
votes their pick, all it takes is for one or two to switch
to a name that they enjoy more. I am hoping that Setizens
would only vote for one favourite name to make it easer
to run it all in a reasonable amount of time. Most of all I
want it to be fun for me, and every one else


Thank you for the ruling. I think I understand, even though I really shouldn't understand, due to English not being my first language. I will now vote again, in another post.

My jumbled word is lasting longer than these tool are.

The mystery tool of the moment is this. It was purpose built for one task only. So you have to have the location and purpose of this tool.

I will not sample (or win) that tool, even if I would work for NASA :-)

Yale researchers say West African Ebola will explode

While U.S. officials scramble to curb the spread of Ebola in the U.S., the disease's epidemic spread in West Africa will likely get far worse unless international commitments are immediately increased, according to a new study led by Yale researchers.

http://www.ctpost.com/local/article/Yale-researchers-say-West-African-Ebola-will-5843529.php

If they had the vaccine back then, see it getting shelved, nobody expected this.
No one cared back then, why invest in a cure when nothing might happen.


And now Mali have its first Ebola case unfortunately.

http://www.bbc.com/news/world-africa-29750723

The Mali government has confirmed the first case of Ebola in the country.

It said a two-year-old girl had tested positive for the haemorrhagic virus. She recently returned from the neighbouring Guinea.

More than 4,800 people have died of Ebola - mainly in Liberia, Guinea and Sierra Leone - since March.

Meanwhile, an international team of scientists has been set up to determine the effectiveness of using the blood of Ebola survivors as a treatment.

It is hoped the antibodies used by the immune system to fight Ebola can be transferred from a survivor to a patient. The study will start in Guinea.

Card: ATI HD7870
CPU Q8200
Two cores left for feeding the GPU

Timings:

My original settings, carried over from AP v6:
-unroll 12 -ffa_block 8192 -ffa_block_fetch 4096 -instances_per_device 2

With the help of Mike, I now try these:

-unroll 16 -oclfft_plan 256 16 256 -ffa_block 12288 -ffa_block_fetch 6144 -tune 1 64 4 1 -tune 2 64 4 1 -instances_per_device 2

Initial result is that the new settings may be just a tiny little bit faster, not much at all, maybe only 30 seconds or so/task.


Next 20
