I've just released a new version of SSRC. More than 10 years has passed since the last release. In this release, the FFT subroutine is replaced and the new FFT can utilize AVX and SSE instructions.

I released version 1.10 of BAUM library. It can now be used from Java. A few potentially serious bugs are also fixed.

I don't know if someone is reading this, but here is a tip for making CPU load lower when we do some processing with OpenCL on nVidia GPUs.

1. Always use pinned memory when you transfer data between a device and the host. Reading and writing buffer always block and waste CPU if you don't use pinned memory.

2. Never use a command that blocks. With nVidia GPUs, all blocking commands involve a busy wait that wastes CPU.  Avoid them and you need to manually poll and sleep in order to wait until a command finishes.

3. If you don't use blocking commands, you need to manually flush the command queue.
