*** Bug 1174256 has been marked as a duplicate of this bug. *** Atlas.x86_64 and atlas-devel.x86_64 are (should be) with SSE3, no need for specialized *-sse3 subpackages. Old 64-bit processors with SSE2 without SSE3 exist, but they are rare these days and atlas upstream no longer explicitly supports them. You probably care about performance, consider rebuilding atlas from source on your own machine.

Fair enough. However, the non-sse3/base F20 (and back to F15 or earlier) atlas rpm contained all sorts of stuff that the F21 atlas rpm does not. I've detailed that below. Where should I look for the missing stuff? I need it to compile plasma. On Fedora 20 we have: $ rpm -qil atlas Name : atlas Version : 3.8.4 Release : 13.fc20 Architecture: x86_64 Install Date: Sun 07 Dec 2014 12:04:57 PM EST Group : System Environment/Libraries Size : 11395870 License : BSD Signature : RSA/SHA256, Thu 20 Nov 2014 06:53:34 AM EST, Key ID 2eb161fa246110 c1 Source RPM : atlas-3.8.4-13.fc20.src.rpm Build Date : Tue 18 Nov 2014 10:14:25 AM EST Build Host : buildvm-07.phx2.fedoraproject.org Relocations : (not relocatable) Packager : Fedora Project Vendor : Fedora Project URL : http://math-atlas.sourceforge.net/ Summary : Automatically Tuned Linear Algebra Software Description : The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. At present, it provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK. The performance improvements in ATLAS are obtained largely via compile-time optimizations and tend to be specific to a given hardware configuration. In order to package ATLAS for Fedora some compromises are necessary so that good performance can be obtained on a variety of hardware. This set of ATLAS binary packages is therefore not necessarily optimal for any specific hardware configuration. However, the source package can be used to compile customized ATLAS packages; see the documentation for information. /etc/ld.so.conf.d/atlas-x86_64.conf /usr/lib64/atlas /usr/lib64/atlas/libatlas.so.3 /usr/lib64/atlas/libatlas.so.3.0 /usr/lib64/atlas/libcblas.so.3 /usr/lib64/atlas/libcblas.so.3.0 /usr/lib64/atlas/libclapack.so.3 /usr/lib64/atlas/libclapack.so.3.0 /usr/lib64/atlas/libf77blas.so.3 /usr/lib64/atlas/libf77blas.so.3.0 /usr/lib64/atlas/liblapack.so.3 /usr/lib64/atlas/liblapack.so.3.0 /usr/lib64/atlas/libptcblas.so.3 /usr/lib64/atlas/libptcblas.so.3.0 /usr/lib64/atlas/libptf77blas.so.3 /usr/lib64/atlas/libptf77blas.so.3.0 /usr/share/doc/atlas /usr/share/doc/atlas/README.Fedora Note the abundance of libraries, including cblas, clapack, f77blas, lapack and pthreads versions. On Fedora 21 we have: $ rpm -qil atlas Name : atlas Version : 3.10.1 Release : 16.fc21 Architecture: x86_64 Install Date: Sun 14 Dec 2014 07:01:03 PM EST Group : System Environment/Libraries Size : 22447409 License : BSD Signature : RSA/SHA256, Mon 03 Nov 2014 11:49:33 AM EST, Key ID 89ad4e8795a43f 54 Source RPM : atlas-3.10.1-16.fc21.src.rpm Build Date : Fri 31 Oct 2014 12:49:38 PM EDT Build Host : buildhw-09.phx2.fedoraproject.org Relocations : (not relocatable) Packager : Fedora Project Vendor : Fedora Project URL : http://math-atlas.sourceforge.net/ Summary : Automatically Tuned Linear Algebra Software Description : The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance.

Where did the rest disappear to? The _text_ still refers to the missing packages. Looks incomplete! All the code is still in the package. Separate libraries are now linked together and you need only libsatlas.so.number (or libtatlas.so.number if you wish the threaded version). This should be simpler than before, one library and you have all the functionality you need. Of course, unfortunately, it breaks builds which expect other libraries to exist. You can delete those '-lf77blas -lcblas ...' flags, only -lsatlas is needed. Merging of separate libraries together is upstream decision and will probably last for some time. An easy, fast and dirty workaround can be symlinking libatlas.so -> libsatlas.so libcblas.so -> libsatlas.so libclapack.so -> libsatlas.so ...

Thank you for clearing that up. Much simpler. But I needed this tip to help me figure it out. Thanks! |
