经过一次跳票，没有很多人注意（才怪）的cuda9.2终于发布了，官方介绍如下：
CUDA 9.2 includes updates to libraries, a new library for accelerating custom linear-algebra algorithms, and lower kernel launch latency.
With CUDA 9.2, you can:
Speed up recurrent and convolutional neural networks through cuBLAS optimizations
Speed up FFT of prime size matrices through Bluestein kernels in cuFFT
Accelerate custom linear algebra algorithms with CUTLASS 1.0
Launch CUDA kernels up to 2X faster than CUDA 9 with new optimizations to the CUDA runtime
Additionally, CUDA 9.2 includes bug fixes and supports new operating systems and popular development tools. Join the NVIDIA Developer Program to find out when CUDA 9.2 is available for download.看上去还是一个小版本升级，没有看到很大的提升。值得注意的是，该版本着重优化了rnn网络的性能。
因为是刚发布的，目前看，各大深度学习框架还没有跟进，预计最近一两个月，会是各大深度学习框架推出新版本的高峰期。
看上去，下载里面还没有18.04的版本下载，或者18.04的repo里面已经包含了也不一定。
