If you are running Rake Search make sure you install the optimised app that [B@P]Daniel created, so much faster than the default one.
For Acoustics, back in September 2017 the admin said:
A GPU application is being developed now, but it is a quite hard problem. I hope, that we will launch it in a couple of months. We also plan to develop an AVX and SSE CPU applications.
So I held off doing too much work waiting for the optimised and GPU apps to appear. To be honest I wasn't expecting a GPU app but it would be good if Daniel could work his magic here. Tasks are taking about 48 minutes for a fixed credit of 42 points, am sure they could be done much faster if they used the hardware fully.
A few days ago the admin posted:
Unfortunately, the GPU developer left our laboratory, so the GPU application is delayed.
On the plus side we have a lot of points to grab at Acoustics as we work our way up from the bottom
