[sage-devel] Google cloud platform research credits

Dear Sage-devel, In mid June 2019 I submitted an application to Google's "research credits" programme for "Google Cloud Platform". The project "SageMath continuous integration" that I submitted was accepted in early July, and I was awarded 5 k USD credits on GCP, valid for a duration of 6 months.

Thanks, using OPENBLAS_CONFIGURE="TARGET=ZEN" make seemed to work. Now, since It will be running a patchbot, it might need to recompile openblas depending on the ticket that is being checked at each time. Is there a way to make sure that this flag is used always? El miércoles, 4 de diciembr

Re: [sage-devel] Error compiling openblas

I suppose openblas fails to recongnise the CPU, resorts to TARGET=ATOM and fails there. You probaby can try setting OPENBLAS_CONFIGURE="$OPENBLAS_CONFIGURE TARGET=???" replacing ??? with the correct value, and rebuild... On Wed, Dec 4, 2019 at 4:09 PM mmarco wrote: > > I am trying to setup severa

[sage-devel] Error compiling openblas

I am trying to setup several virtual machines to run patchbots (for different distros). I am getting the following error when trying to compile Sage from source: n not be used when making a shared object; recompile with -fPIC /usr/lib64/gcc/x86_64-suse-linux/7/../../../../x86_64-suse-linux/bin/

[sage-devel] Simple integral raises AttributeError

Hi, In Sage 9.0.beta8 we have sage: a = var('a') sage: integrate(1/(x^4 + x^2 + a), x) ... AttributeError: 'RootSum' object has no attribute '_sage_' The same error occurs in Sage 8.9, but not in Sage 8.8 (and below). In Sage 8.8, we have instead: sage: a = var('a') sage: integrate(1/(x^4 + x^
