I'm no English mayor, but... consider the following.
On the homepage, it says:

DENIS is a project created to help researchers in electrophysiological modeling. Electrophysiological models are a powerful tool to study the electrical activity of cells under normal or pathological conditions. These models also can help to predict the effect of drugs in the cells of the heart or the brain.

These models are complex and it’s neccessary to simulate them many times (varing the conditions or some model parameters). For this reason, researches usually need a high computational capacity. We have created DENIS as an infrastructure of simulation to help researchers. The five pillars of DENIS are:

DENIS uses volunteer hosts to compute large packets of cardiac electrophysiology simulations.
You can participate by downloading and running a free program on your computer. See how to collaborate. Using the idle time of your computer, you can help to resarch projects giving valuable computer capacity. You can read more about resarch in DENIS in the section Science.


I think it sounds better (English-wise):

Like I said... I'm no English mayor, but I think this reads a bit better. If you have whatever information in Spanish, I'd be more than willing to translate it for you in English. I translate wikipedia articles back and forth between Spanish and English all the time... so, I sort of enjoy sharing translating :)

The BOINC logo at the bottom incorrectly links to: http://boinc.berkeley.edy/
It should rather link to: http://boinc.berkeley.edu/

Is there a Windows 32 bit app available? I have 3 machines that are unable to run 64 bit Windows.


Or AVX "1" ? :)

Yeah, DENIS is gonna crash.

AVX2 version.

Download:
http://optos.sesef.pl/denis or https://dl.dropboxusercontent.com/u/1452459/denis/denis1.6.1_avx2.zip

You should get up to ~30% speedup depends on cpu type, on new Intel Skylake even more.


My laptop trashed all the units using this one, I reverted to the old one and it is fine again.


^ Same result. On W7 i5 2400



AVX2 is available only on i3/i5/i7/xeon 4th gen or newer processors. So only i3/i5/i7 4xxx+ or Xeon v3+


Is an AVX "1" version worth it at all? I have a 3rd generation CPU on my main laptop which only support AVX. Not AVX2.
I'll try this app on my 4th generation laptop tho.

Amazing how you managed to squeeze out even more efficiency. Updated my Linux and Windows binaries. Looks OK. Thanks!

If a system can support both SSE2 and SSE3 versions, is there an advantage to using one over the other? Some very quick tests on my 64 bit Linux systems show pretty much the same times for both versions (and they are about 85%-90% faster than the stock version).

Also, any chance of a 32 bit Linux version for SSE2? I've got one lone cruncher of that kind that could use some help.

(New to this project, not to BOINC.)

Thanks
Charlie


If you notice, his URLs both link to the SSE3.

As a side question, do these take advantage of AVX?

Their servers seem a bit slow lately. Maybe it's the opt app that's causing too much traffic?
I'd reckon every WU averages about 3 minutes on my computers... I'm running 16 WUs simultaneously... that's about 5 requests per minute JUST from me.

Maybe trying for AVX could bring an additional strong boost...

12K RAC for 24 HT cores seems OK to me. My 8 HT cores gives me about 4.5k RAC.

The first test are all ok. At the moment we didn't have see any differences in the results between this version and our 1.05. We can't support this version, and we haven't check if the app just do what if have to do.

We will contact with the developer soon and we hope that we can add this optimization to the official app.

Regards, Joel.


Sweet!
