11) Message boards : Generalized Fermat Prime Search : Gefener 3.03 fails on slightly overclocked GPU (Message 79305)
Posted 2855 days ago by Profile matszpk
I fixed problem. Now I am crunching on mem=1270MHz. and apparently is good (no errors).
That rights. genefer is very sensitive for mem overclocking.

Hi, all.
I was overclocked slightly my GPU (radeon hd 7850). In the stock my card have: core=900MHz, mem=1200MHz.
Few months earlier, I overclocked to core=1000MHz, mem=1290MHz (and ofcourse I made stress tests like memtestCL and others).
In my current setup, Genefer fails after few minutes with maxErr exceeded error. How much is genefer sensitive for GPU memories clock (must be in stock frequencies)?
I am using AMD Catalyst 14.6 beta (from May) on the Linux 64-bit.
Thank you for any response.
PS: Fans speed while genefer computing was in 41% and GPU temp was not higher than 63C.

TRP Sieve has been ported few weeks ago and works very well (I tested on my htc sensation phone). I fixed its wrapper and should'nt behaves unexpectedly.

I have important message: I moved NativeBOINC to my new domain: nativeboinc.org.
New version of the NativeBOINC will be downloading binaries and news from files.nativeboinc.org. Currently I am preparing website for NativeBOINC.
New info at https://github.com/matszpk/native-boinc-for-android/wiki/News and fetched news by NativeBOINC. New APK also in files.nativeboinc.org/android.

but this workunit finished unexpectedly (stopped at 45.8398% progress by signal or other reason). Sometimes android can kill application when it have too small amount of the memory. I found bug in the sr2sieve wrapper (can handle improperly unexpected app exits, for example kills, termination by signal).

Unfortunatelly I found dangerous bug in wrapper (can improperly handle unexpected app exits). I really recommended to update primegrid apps, because these bug can causes sending incorrect results as correct!.

I wrote (and published) unofficial port of Riesel Problem app for Android. Unfortunatelly during computations Android killed apps and boinc sent result to your server. One of incorrect result was ACCEPTED by your validator even it was INCORRECT. Incorrect result: http://www.primegrid.com/result.php?resultid=400143100. Currently I am working on fixing this problem on application's side. I am using sources from https://sites.google.com/site/geoffreywalterreynolds/programs/sr2sieve and [url]http://sourceforge.net/projects/primegrid/[url]. My sources available at https://github.com/matszpk/native-boinc-for-android/[/url].

Hi. new app has been published. It is Riesel problem sieve. It optimized for ARM NEON extensions. I encourage to testing app. Workunits are short and can be quickly computed on the devices without NEON extensions. Unfortunatelly, deadline for these workunits was shorten from 7 to 4.7 days (for olimpic challenge???).
Ok. I encourage you to testing and updating primegrid apps.
Nice crunching.
