Why not? It is. Calculating pi is trivially parallelizable. If you wrote good kernels, calculation distribution could be exactly the same.

Blockchains that perform computation (e.g Eth), aren't doing parallel computation as we think of it.

They perform the same computation on every node, there's no way to split up the work between nodes

But what role would a Blockchain have in the parallel computation of pi?

[berbec]

Besides Block chain being useless for this purpose, calculations of pi are disk io limited at the current time.
