Potential Issue: Atomic buffers not cleared between trials

await primitive.execute({

This line is executed repeatedly when running multiple trials (params.trials > 1), but the underlying atomic buffers are not cleared. As a result, atomics may accumulate values, causing decreasing performance or incorrect results after several runs.

I’ve attached a screenshot showing the atomic values of spineBuffer and scanBump over multiple trials for reference.

Possible solution: Clear atomic buffers after each trial

After clearing it :

So should the fix go here?

gridwise/primitive.mjs

Line 794 in d0ecc7f

/* just use the existing buffer */

I think we could just call clearBuffer there.

});

I thought this place was good because it allows us to clear it before opening the compute pass.
