Subject: Re: [patch, libfortran] Speed up cshift for dim > 1
Date: Fri, 16 Jun 2017 15:14:00 -0000	[thread overview]
Message-ID: <B1F0FF5A-F160-494F-9C45-8EA029B41933@lps.ens.fr> (raw)

Hi Thomas,

Your patch works as advertised! For the record, the following CSHIFT is still 4 times slower than the DO loop

    td(:,:) = cshift(array=t(:,:), shift=vect(:), dim=1)

Thanks for working on this issue.

Dominique
