Hello,

I am going to change computer equipment since the one I use is borrowed, taking the data to the new computer equipment. Will I lose the generated data?

You can sign up to the same projects with your new computer(s). Tasks in progress will almost certainly crash. Even with identical computers you would need to be both very lucky and have a very good knowledge of BOINC to transfer them.

Maybe with Linux, but with Windows it's just copying the data directory over from one computer to the next, install BOINC on the new computer and continue where you left off.

I thought there were problems with having to have a very similar CPU?

Most of the science applications run on an "Intel-compatible CPU", so that includes AMD, Intel, and anything else (though not ARM).

I say "most" because there are GPU applications, which require the correct GPU, of course.

I know what you meant, the advice is to go from an Intel to an Intel CPU, and AMD to AMD CPU to make sure BOINC doesn't hiccup on recognizing the CPU. Maybe the advice is still sound when going from a 32bit to a 64bit CPU - and certainly the other way around when the applications are 64bit - but I don't think it matters much these days.

Thanks Jord, I am still learning. I think it may also be the project where I have most experience, CPDN is much more fussy about such things than some others.
