NEHALEM arch detection #69

ViralBShah · 2011-10-28T15:53:56Z

The build process seems to be unable to detect NEHALEM correctly. I have found issues on a recent macbook air (core i7) and on an ubuntu 11.0

Hi Viral,

What's the version? Is it v0.1alpha2.2? Could you try the lastest
version or develop branch on github.com?

Thank you for the report.

Yes we were on 0.1alpha2.2. I just updated to 2.4, and am waiting to hear back from some people who are trying it out, as I don't have a nehalem box myself.

Hi,

Do you or your colleague meet the problem on Nehalem again?

Thanks
Xianyi

ViralBShah · 2011-11-04T07:29:28Z

I built with DYNAMIC_ARCH=1, and things don't crash anymore. I assume it is using the right version - but don't have a way to tell.

BTW, julia users still keep reporting this error. If using DYNAMIC_ARCH=1, is it possible that this can be made smooth by detecting at runtime, and using a safe fallback in case the detection fails, while printing a warning?

xianyi · 2012-01-26T12:25:13Z

Hi Viral,

Thank you for this report.
Now we are in Spring Festival holiday. I will check this bug in next month.

Thank you

Ok, I now have a NEHALEM machine and am using 0.1alpha2.4, and it fails with the same error.

xianyi · 2012-02-13T09:08:22Z

Hi Viral,

I think Mac Air 2011 equips with Intel Core i5-2557M (http://ark.intel.com/products/54620). This CPU is Sandy Bridge microarchitecture.

Because we didn't optimize OpenBLAS on Sandy bridge. it couldn't automatically detect this CPU.

Thus, you should set "TARGET" flag on compiling, e.g.

make TARGET=NEHALEM

Xianyi

ViralBShah · 2012-02-13T09:10:49Z

It would be nice if NEHALEM is set automatically for Sand bridge arch,
with a warning message. Currently, this just breaks the build, and it
would be nice if that could be avoided. Would that be possible?

Thanks,

Hi Viral,

OK. Pleas give me your CPU processor number, e.g. i5-2557M.
I will add detecting this cpuid into OpenBLAS.

Thanks

Xianyi

ViralBShah · 2012-02-13T09:30:53Z

It has also been reported by people using Linux etc. Can we make it
default to NEHALEM for all CPUs later than Nehalem, until support is
added?

Hi Viral,

I just added those CPUs. You can download it on develop branch.
Could you help me test it?

Thanks
Xianyi

ViralBShah · 2012-02-13T14:21:05Z

I am traveling, and don't have access to that computer where I need to
try it out. I should be able to test it out next week and get back to
you.

OK. I have tested it on my core i5. It works fine.

A request - is it possible for you to make a release with this? This is the number one reason the julia build fails right now.

xianyi · 2012-02-19T04:04:34Z

Hi Viral,

Did this patch solve the problem?

If it solves the issue, I will release a version today.

I finally could try it out. It works great. Would be great if you can release a new version. Thanks!

Hi Viral,

I have released the new version, 0.1 alpha 2.5
