cuptiFinalize not defined in cuda7.5

[putcn]

I am trying to fix Paddle's manylinux1 build. It will build Paddle based on CUDA 7.5. And it failed on

[21:34:51][Step 1/4] In file included from /paddle/paddle/fluid/platform/dynload/cupti.cc:17:0:
[21:34:51][Step 1/4] /paddle/paddle/fluid/platform/dynload/cupti.h: In member function ‘CUptiResult paddle::platform::dynload::DynLoad__cuptiFinalize::operator()(Args ...)’:

Looks cuptiFinalize and related APIs are not available in cuda7.5, which fails the nightly build of cuda7.5 cudnn5.

@panyx0718 cuptiFinalize is used in profiling.

So, are we going to ditch the support for cuda 7.5?

There are 2 solutions, we update the cupti API call to support cuda 7.5, or we can disable timeline support for cuda7.5. Looking into it

I am using cuda8.0 and get the same error. Is there any update about this problem?

[panyx0718]

Is there something broken recently? cuda8 used to work.

I have a PR that can fix the issue:
#10500

But cuda7.5 gives me another not quite related error after this one is fixed:

closing this as we have decided to stop supporting cuda7.5
