Good day,

I'm an user of Win7Pro 64-bit and BOINC Manager in 64-bit version. But I see in my TaskManager that miniRosetta 2.14 is a 32-bit process. Can you create 64-bit mR version for best performance?

Thanks.

You won't see much improvement with a 64-bit rosetta application. So there's no need to make a 64-bit application.

im wondering why will rosetta not benefit from running at 64bit?

Why do you think it would? Rosetta doesn't currently come close to the 4GB RAM limit that 64-bit removes.

Here's an old thread on 64-bit. The posts by Mats Petersson are a good starting point as he both knows the subject matter and had seen the code:

https://boinc.bakerlab.org/rosetta/forum_thread.php?id=1523#15242

It might be that minirosetta, which was released more recently has changed the facts, but I doubt it.

The guys at the bakerlab are pretty handy with code and I'm sure they'd release a 64-bit client if it gave them more computer power without being overly onerous.

64bit processors do more then lift memory constraints. They allow you to do operations on 64 bits in a single clock tick, rather then 32. But if you are only using 32bit floats in your calculations, they take just as long. So the applications that benefit the most from a 64bit processor either need more memory, use a lot of double float operations, or move large amounts of data in and out of the CPU.

Think of it like 64 train lines rather then 32. Twice as many lines only helps throughput if you frequently have more then 32 trains trying to use the route at the same time.
