Compilation issue on the PowerPC

[eddy16112]

I try to use TBLIS on the PowerPC, and I am able to compile the TBLIS, but when I try to include a header file, I am getting the following error:

In file included from /autofs/nccs-svm1_home1/wwu12/install/TBLIS/include/tblis/util/../external/marray/include/expression.hpp:4,

The error is from https://github.com/devinamatthews/tblis/blob/master/src/external/marray/include/expression.hpp#L4
I can add the -DNO_WARN_X86_INTRINSICS to mute this error, but I think the include <x86intrin.h> is not masked correctly in the expression.hpp. I also want to know if TBLIS supports PowerPC vector intrinsics.

@eddy16112 TBLIS doesn't currently support PPC/POWER. In the near future TBLIS will work off of the BLIS framework which will allow support for x86_64, arm32, aarch64 and POWER.

Hey @devinamatthews, do you know what the timeline on this looks like? I'm interested in running some experiments on a PowerPC machine using TBLIS as well.

[devinamatthews]

Within 3 months or so is my best estimate.

Hi @devinamatthews, is TBLIS over BLIS available to try out yet?

[ipdemes]

@devinamatthews I got the same question as @manopapad . We were trying to build tblis for aarch64 and got a lot of errors.

[devinamatthews]

I finished the first version of the plugin architecture in BLIS on Tuesday, so getting there!!

[ipdemes]

Is that something we can try? I am OK to be an alpha tester

[devinamatthews]

I still have to do the TBLIS side but when there's an alpha version ready I'm happy to have testers.
