hcc with "New GNU Portable Threads" #884

Open suvayu opened 6 years ago

suvayu commented 6 years ago

I am on Fedora 28, running on 2400G, and wanted to try out Tensorflow with ROCm (with kernel 4.19). So I tried to install rocm-dkms from the Centos repos mentioned in the docs. However that fails because I do not have Pth on my system. I did some digging and I see that Pth was deprecated for nPth on Fedora. Is there any possibility for building hcc against nPth?

Currently, Fedora is not an officially supported operating system (https://rocm.github.io/ROCmInstall.html#software-support).

@david-salinas, thanks for the response. I have read that page, I linked to it above! I'm asking if compiling against nPth is possible, and if so, how may I go about it?

A somewhat broader comment: it's a bit strange and frustrating to encounter situations where, the latest kernel is required but the supported distros are among the slow moving conservative ones.

I don't think the current release supports > 4.15 anyway

With the latest kernels (> some version of 4.18.x, or 4.19 I think) the drivers are available upstream. All I need are the userland libraries to work.

In any case, I have resurrected the old Pth library in a copr as a temporary hack. But I have had other issues :-|

I haven't tried to build the dkms on debian in a while, will give it a go

This is why I have three operating systems on most machines!

Following https://github.com/RadeonOpenCompute/ROCm/issues/567#issuecomment-430771267 seems to get it working with npth.
