CPDN models are very floating point intensive. Since a cpu core only has one set of floating point units, two threads have to compete for resource. That's why your throughput drops.

Yes, I've noticed this apparent behaviour too. I think this is down to the way the code is compiled; the compiler is told to add in conditional code for different instruction sets depending what chip it finds. For instance, instructions for SSE2/3/4.* are included. When the code executes it will use different assembly instructions depending on what capabilities it finds on the chip. Older chips therefore will not necessarily be using the same assembler as more recent chips. That's great for speed but a bugger for debugging.

The executable sent out with WaH is also old. It's not been recompiled for many years and that could also be introducing issues.

BOINC crashing when left unattended is a new one for me. The only times I can remember BOINC itself crashing as opposed to tasks is the recent bug that would sometimes make it crash switching between advanced and simple view then back again. I think that has been fixed now but not 100% certain.

This happens to me once in a while, I'll come check on it and find BOINC isn't running. I can't remember when the first time was, this year or last. I think this was the first time with the latest version (7.24.1). It was also the first time with CPDN running which was costly due to loss of tasks and a lot of processing time. I haven't tried to investigate it in any way yet.

If it happens again it would be good to check in the system logs to see why it failed. I'm assuming this is the Windows client only and not linux (I've never seen it myself).

and others due to BOINC seemingly crashing

I am sure alot of the hard fails are simply due to this and not because of an inherent problem with the model perturbations. Not sure whether CPDN will decide to rerun them or not yet.

I was rather shocked recently to find a tool to discover what package contains a file you need to run programs. Useful if the package containing what you want changes with a new version or really useful if compiling BOINC from source.

apt-file find 

will if you type or paste the name of the missing file tell you the package you need to install to get it. Had I known of it earlier it could have saved me many hours of searching the interweb to discover what package I needed. I don't know if there is anything similar for RPM distros.

I'd like to be able to delete the old, obsolete computers in my account, some of which were scrapped over ten years ago.

My hope is that those in charge have learned from the effectiveness of the shorter deadlines given to OIFS tasks.

Just so I do not be considered greedy, I do not wish to hog an unfair number of tasks, but OTOH, I do want a large enough number of tasks on my machine to coast me over the dead spots.

Because the region covered is much bigger than the ANZ region, these tasks will be long if they get here. Currently looking like about 50 days on my Ryzen. Slower machines will be well over 2 months even if running 24/7.

Yes DreamLab only works when power is plugged, whether charging or not. I've not noticed any temp bump from extra power. It's a well behaved app. I use both my phone & chromebook, though the CBook is significantly faster.

It uses a very small amount of memory. Have been trying to find out exactly what the Tropical Storms app is computing in such a small footprint but there's scant details about it on the web (other than the publicity). From what I can gather it's crunching small amounts of data rather than running a real model but it's hard to find out more details.

WCG has been hard-down again, for some hard drive failure issue or another.
