I discovered (with 32GB of RAM ...) that RAM usage crept up and up. You have to have some program with very serious memory leak (bug) to fill 32GB in one day. (I have 3 GB of RAM for Windows XP - sometimes I don't need a Reboot for weeks. Only restart per 2-3 days the only program with memory leak here - cracked (by Russians) Skype 4.2.0.187 - I hate the new Skype (No, I will not 'update'; No, I am not afraid of Russian cracks) ) Which program uses so many GB of RAM is easy to see by any of: Windows Task Manager Process Explorer Process Lasso System Explorer ProcessHacker (no need of links - first result in Google is OK for all of them) - ALF - "Find out what you don't do well ..... then don't do it!" :) |

Last modified: 29 Mar 2015, 15:01:09 UTC Several programs I use have "Memory Clean"/"Memory Usage Trim" Options: Memory Cleaner (Koshy John) Process Lasso System Explorer In fact all such programs call standard Windows functions to do the job Usage of such programs/tools to "Trim Memory Usage" of processes may be helpful up to some point. Windows do this "Trim" by its own when an active program want more Memory then RAM is free at the moment. The real cure is to find the 'bad' (RAM leaking) program, then find different version which don't have the bug or find alternative program for the same job. If no alternatives/versions are viable - restart the 'bad' (RAM leaking) program as often as needed (e.g. once a day). P.S. BUT I don't think that the Atom CPU that was in the beginning of this 'RAM talk' have any issue. The Atom is just not so fast ;) - ALF - "Find out what you don't do well ..... then don't do it!" :) |

I had there estimated time 2000 sec, after day it growed up to 20000 sec yes, i know that atom CPU is like a CPU unit of an calculator, but i have another mobile CPU attached on another project, it is intel pentium M 1,7GHz and is working on tasks without any issues, when is on some task written 32000 secs, then it will do it for this time,... and it is older CPU as intel Atom with 4 cores (2 real cores, 2 threads) and 64bit architecture... so it is strange for me, that the newer mobile processor is slower on this project as an 15 years old CPU... |

Last modified: 1 Apr 2015, 0:46:06 UTC Could the download limiting server software be changed so that it doesn't count Download failed as a reason to stop a computer from downloading more workunits? That should help get rid of the workunits set up with missing input files on the server faster, without the current restriction on how many good workunit get done each day. I've found that there is no need to abort workunits with Download failed - just use the normal method for reporting them back to the server. |

So what is currently the suggested action from the users? Keep going through the faulty WUs, or don't bother? Looking at a tcpdump of my traffic to ateroidsathome.net, and trying the URL in a web browser, it seems that instead of the WU's data, the server provides just the 39-byte MD5 sum. Going by the presence of "Content-Location" header and its contents, I'm guessing this is caused by a misconfigured mod_rewrite in apache..?

What is this nonsense. 10 task daily limit on a 2600k?

Sounds like too many errors were reported so your work fetch has been throttled, this is standard at alot of projects, but since you have your pc's hidden I am only guessing. As you return valid units your daily quota will climb rapidly, if I am remembering right it's almost doubled every day as long as no more errors creep in again. |

What is this nonsense. 10 task daily limit on a 2600k? This computer doesn't have an Nvidia GPU. Looks the download failure rate is 90%+. I've had 4454 failures to get 413 tasks that can be run since March 19th. Makes no sense to me why this issue has not been fixed. |

Last modified: 2 Apr 2015, 19:36:12 UTC Makes no sense to me why this issue has not been fixed. Well, the reason is very simple: Administrator of this project is busy. Obviously he hasn't had enough time to do it yet. He will fix it when he has enough time to study what causes the problem plus apply the fix. |
