Any update on GPU app? It's still in development or is stopped?

At this pace whe are talking :
87554 - 11587= 75967 / 26= 2921 days /365= 8 years

I think more users are needed
Maybe upgrading the WU generator poperly

We are confident that your team will figure the best solution for the project
Keep crunching :)

Allowed what? This large number of WUs?
This host has 48 cores. max task quequed for each core =8 48x8= 384
According to elaboration time, he need 2 days to complete theese wus

Hi David,
are you running all 64 thread on this monster? http://gene.disi.unitn.it/test/show_host_detail.php?hostid=44901
15700s is impressive for 64 thread

AMD is doing grat job for BOINC users

It is a normal practice for each challenge issued on every project.
When starting date and hour is set (in this case March 4th 0:00 UTC) you calculate when you can begin download wu to return after the challenge is started (in this case 5 or les days). The user is interest to execute wu an upload them, before deadline to recieve credit.

Personally, doing bunker, i do some maths to calculate the right amount of wu needed in this period
However many user don't do this


By the way, theese challenge are kind of boost for the project, because maybe some partecipant decide to stay on the project
It's also a server' stability test

All theese wu are only bunker fo the upcoming challenge on the project, issued by TSBT, starting March 4th
http://gene.disi.unitn.it/test/forum_thread.php?id=241

You can avoid the wu limit (10wu per core) increasing the value "ncpus" in the cc_config.xml (only in the bunker construction phase)
8) Message boards : Number crunching : Report Deadlines (Message 1495)
Posted 11 Feb 2019 by Profile Buro87 [Lombardia]
It happen on all project. if you have a lot wu with tight deadline, boin try to finish them. For example yesterday on WCG with subproject FAH (1 day deadline)and MIP (10 days), boinc complete firs all FAH wu because i have set request for 3 days work.

If you have the internet connection always on, try to set request work for 1 day or less. In that case boinc will switch project because it see that wu are not so in hurry

Hi, another user (Luigi R.) from our team Boinc Italy has done theese app_info.xml. Try it and let us know if they work
Make sure that you have the correct app

Windows
http://gene.disi.unitn.it/test/download/gene_pcim_v1.11_win64__avx.exe

Open Notepad an copy the following text and save the file as "app_info.xml"

11) Message boards : Number crunching : New TCGA workunits (TCGAz) (Message 1412)
Posted 5 Dec 2018 by Profile Buro87 [Lombardia]
Thanks for the warning - some of these jobs seem to need considerably more CPU-time. 17 h for 32% in one case. Anyhow, if there's a chance they come to an end I'll let them run.



if you can, let them run. If you need to turn off your pc at the end of the day, abort them. If you are in the middle of long checkpoint, and you turn off your pc, you'll come back to the previously checkpoint, losing your time.
One wu stay at 52% for 9h. Total run time 33h


I refer to old TCGA wus

if you click on "Application details" you can see that: the sse2 version is more profitable for you (3,40 GFlops) against avx (2,83 GFlops)
this is the reason why you recieve much more sse2 wus

This afternoon we will have a meeting to discuss various issues, among them the new big experiment and the efficiency of the system. I will update you all after that.

I have just generated a few workunits related to the new experiment, just a test, for the moment, checking if everything will work well.


Hi Valter, any updates from the new project?

We are back to zero work units available for down load. Since the Admin has not responded on this thread I will try to send a PM to him.

Why don't you try to overclock your Ryzen CPUs? With the stock cooler you can do it to 3.6-3.7 GHz without overheat it. I have a Ryzen 7 1700 at 3.9 GHz and it works perfectly.


My R7 1700 is runnig @ 2,7 GHz to save Energie.
Electricity is quiet expansive in Germany.
At this speed the R7 uses less than 50 watts.
@ 3.6 GHz it would be around 90 watts or more. :)



You just set cpu multiplier to x27? Or you have add an undervolt?

I will try to set my r5-1600 from 3.4ghz (1,07v vcore) to 3-3.1ghz
I also test if CPU stay less time waiting for memory

However, 0:40 ~ 4:00 hours for every WU.
AMD Ryzen 7 1700 at 3.9 GHz
RAM 2x8GB 3200 MHz CL16


My bottleneck is ram bandwidth because i have only 1 stick

as explained by Daniel at the end of this thread
http://gene.disi.unitn.it/test/forum_thread.php?id=135#1229
in my case, overclock on CPU is not so good

These are running about 5 hours on my Win 10 4770K @ 4GHz...



as explained by Danien at the end of this thread

with TN-Grid app, ram frequency is more important than cpu speed
