1) Message boards : Number crunching : Nvidia GPU: OpenCL vs CUDA55 (Message 19991)
Posted 1180 days ago by SuperSluether
I'm receiving a mixture of OpenCL and CUDA55 tasks for my Nvidia GPU. I understand the difference between them, but why is there a separate OpenCL app for Nvidia when it can use CUDA55? Is this for compatability with older cards?

Edit: Does CUDA55 offer any advantages over OpenCL for this project?
2) Message boards : Number crunching : Mini Collatz Aborted By Project? (Message 19907)
Posted 1205 days ago by SuperSluether
I've had computation errors before, but I've never had many with Collatz, and I've certainly never seen a task aborted by the project before... Does this mean anything?

Maybe OpenCL speeds things up in other projects, but for this project it's just a waste. Mini Collatz and Mini Collatz using OpenCL both run for about the same time and generate the same amount of credit. The only difference between OpenCL and non is that OpenCL tasks run on all available cores, which means that it is the only task running. Am I missing something? Was OpenCL used for something other than optimizing the tasks on all cores?

Remind me why we're endlessly crunching on this project? It's impossible to compute every number down to 1 with this theory, so when is it decided "true"?


When we have computed every number down to 1 of course! Crunching thru Boinc is about choices, you can crunch here, there or even everywhere, your choice. On of the REALLY nice things about Collatz is the Admin who runs the Project, he is very responsive when problems arise and as a result the Project is up 99% of the time. To me that alone makes it my go to project when I need to just put my pc's on cruise control for a bit. Solving a math problem is another bonus for me!


But like I said, it's impossible to compute every number down to 1. Besides, there comes a point (somewhere after quadrillions) where nobody counts that high.


Why can't we count that high, we are using pc's now not our fingers? And no person will fly to Pluto in our lifetime, yet Nasa sent a spacecraft PAST that point and it's still going! Science is not about 'we can't', Science is about 'why CAN'T we'. It's okay if you stop, the rest of us will carry on without you, people come and go all the time.


But isn't it a waste of computing power if no solution will ever be found? There are projects out there that could actually help people and actually solve problems, but this one will never have a solution.


This is becoming a circular discussion, you are making assumptions, just like the Collatz Conjecture! Prove to me that it will NEVER be solved and I will leave, until then I choose to crunch here! Just remember NEVER is a VERY long time, and with computers we can calculate pretty fast!


Numbers go on forever. Even with super fast computers, you'll just find bigger and bigger numbers with more and more digits. However, this leads me to ask how other mathmatical theories were proven...

Any way I can get that "completed" signal send ?
I have since received new Collatz WUs, but I hate to see my PC work for nothing for another month.


Go to the projects tab in BOINC Manager, select Collatz, and click the Update button. That assumes there is an entry listed as "Ready to Report" under tasks. If you don't finish a WU prior to the deadline, BOINC will abort it.

If the large WUs are taking a month to complete, you may want to deselect it from your preferences so that you only get the mini or solo WUs.


Just a quick question, I'm a desktop user and currently only have the onboard Intel graphics. In my preferences, I have everything selected, but mini and solo are the ONLY tasks I ever get. Are the larger ones specifically for better GPUs?

Yeah... I use Advanced System Care to optimize my PC and Driver Booster to update drivers. Some people say they just cause more problems, but I haven't had any as of yet. There was this one time when the onboard graphics driver updated, and gave me lower FPS though. That was the only driver I rolled back.

Posted 1231 days ago by SuperSluether
Now I feel ridiculous. For whatever reason, BOINC, my antivirus, and a few other programs acted as if they were reinstalled. The error must have reset something in registry.

I use IObit Driver Booster. The only bsods I'm having with this system is when my overclock is unstable. (I think I've got it now, but it was a mess trying to get the right voltage)

Posted 1232 days ago by SuperSluether
I just had a blue screen error, and when my computer restarted I found that all tasks from this project still had their runtime, but started over from 0%. Do tasks from Collatz checkpoint to the disc at all? I just lost 1.5 hours of computing from this.

As for why I had a BSOD, I've been overclocking recently. I thought I had a stable overclock, but it crashed after about 6-8 hours. (I think I've got it now though)

How do you know when the project is done, and what happens when it's finished?
