Hm, willst Du Dir nicht lieber ne PS3 besorgen? Würde sie mir dann gerne mal ausleihen, um wenigstens eine WU bei PS3grid zu crunchen.....

Ich habe für meine kompletten Teile weniger bezahlt als die PS3 wert ist, und wie schon vorher gelesen, CPU Lüfter nicht mehr als 900U/min, bräuchte nur noch ein leises Netzteil :wink:

September 6, 2007
I notice there are some concerns about forums and the like, but unfortunately I'm the only person working on this project and I am only a college undergrad doing some research on the side. I appreciate your interest in this project, and also your commitment to keep things respectable while I am away. Currently I'm working on fixing some bugs in the actual program, and once I get something working I will add binaries for new platforms and update the web interface. Hopefully I can get everything running smoothly, and I hope to have project working correctly sometime this weekend or during next week. Once that is finished I will get right on top of web stuff. Thanks for your patients!!

March 23, 2008 Reduced Granted Credit
Due to the fact that the application has been highly optimized in the last few versions, most people agree that the granted credit is way too high for the project by a factor of 3. We've scaled credit down to keep it in line with other projects, so if you notice reduced credit this is why.
Endlich, zurück zur ursprünglichen Vergabe.

Aufgrund enormer Serverbelastungen wurden die WUs jetzt um etliche Std. verlängert.

Credit Changes
November 3, 2008

After some discussion, we've decided to move the credit generated per workunit back to where it was, however reduce the maximum possible credit generated per hour in half -- this should keep our project in line with other BOINC projects, but not penalize people not running optimized apps. These changes should effect all newly generated work so it might take ahwile for everything to propagate out.

CUDA Update -- Working Compile Script
May 22, 2009
I've updated v0.04 to the code release directory. This should work correctly with the compile script. The next steps on our to-do list are getting checkpointing working correctly for it (i'm pretty sure its not working), and compile time specified single or double floating point precision. In the next couple days I should get the milkyway_gpu forums up and running and some test work units available.

CUDA Application Released
August 26, 2009
The CUDA application has been released on BOINC, please see this thread for more information. The Milkyway@Home team appreciates your patience in reaching this milestone. This code has been implemented and tested on the GeForce GTX 285 donated by NVIDIA to the Milkyway@Home research team.

We are therefore launching the following "thank you" and fundraising campaign. On September 1, 2011, we will run MilkyWay@home with double credit. Hopefully, this will at least make up for some of the credit lost when MilkyWay@home was not operational for software, hardware, or air conditioning emergencies. We understand that these have been frustrating to some users, but be assured that they were much more frustrating for us.

In addition, we will run MilkyWay@home with double credit for one additional day for every $500 raised between now and September 1, 2011.
Heißt es gibt für alle den ganzen 1. September bei Milkyway doppelte Credits, das ganze wird danach um je einen Tag für je 500/EUR Spende im Zeitraum zwischen heute und 1. September verlängert.

Gruß Odi

It appears that I have made a mis-step in management of MilkyWay@Home, regarding double credits for fundraising. I believed that this had been done before. I have since discovered that not only I was incorrect, but it is also inconsistent with the BOINC credit system. As volunteers, you have donated enormous computational resources to my group, and on top of that have created a powerful community that not only helps us with software but also teaches us how to be responsible members of your community. We will be running double credit two days this week to make up for lost credit in the past, but we will not be running a double credit fundraiser in September. I apologize for any inconvenience this has caused. I will need a little time to understand what the right way is to do this, so stay tuned.
We'll be running two days of double-credits this week on Wednesday and Thursday to make up for outages earlier in the summer.
Heißt die Doppel-Credit Spendenaktion ist gecancelt, aber es gibt diese Woche Mittwoch und Donnerstag zwei Tage an denen, wegen der Ausfälle Anfang des Sommers, doppelte Credits vergeben werden.

Separation updated to 1.00

#19 Post by odicin » 08.02.2012, 18:29

I've updated all of the separation applications to 1.00. For changes people might care about,

- The old CAL version is gone; it's replaced with the OpenCL application. On AMD/ATI GPUs (older than 79xx) it is using some hackery to use the same IL kernel as before so it should be as fast. However this also means the Radeon 38xx cards aren't supported with new stuff.

- Radeon 79xx stuff should work

- The occasional validate errors from empty / truncated stderr should stop

- AVX will be used if available on Linux and Windows (64 bit only for Windows)

- I've increased the default GPU target frequency so GPU stuff should make things less laggy on average. You can now also configure this with the web preferences now so you don't need to use app_info stuff if you want to play with that.

- Partial workaround with high CPU usage with recent Nvidia drivers.*

* It should cut down on the CPU usage a bit while not sacrificing too much. I would recommend not using it unless you are very unhappy with the CPU usage on Nvidia. There are options to change the polling mode if you want to lower the CPU usage further while not slowing it down. (--gpu-wait-factor (default = 0.75) and --gpu-polling-mode (default = - 2) work similarly to how they did with the old CAL one, but slightly different). With the default of -2 it will use mode -1 unless it is an Nvidia driver newer than the one that introduced the high CPU issue, where it will use mode 0. Mode -1 uses the correct waiting method, mode 0 use the correct waiting method with an initial sleep based on time estimates, and modes > 0 are a polling period in milliseconds. The wait factor is a sort of correction of the time estimate used for the initial wait. The default is 0.75, to wait for 75% of the estimated time before trying to poll.
In diesem Zusammenhang gibt es in den Prefs nun auch endlich die Möglichkeit zwischen Separation und Nbody auszuwählen. Die Nutzung der app_info ist daher nicht mehr nötig.

Die OpenCL Tasks können auch auf BOINC Clients 6.12.X gerechnet werden, obwohl diese Version die OpenCL Erkennung noch nicht unterstützt.
