I suppose you need intimate knowledge of the target CPU and architecture? ggotoblas2

Compiling with GotoBLAS2

GotoBLAS focuses on optimizing the matrix multiplication routine, a computationally intensive standard matrix operation that can significantly slow processing time.

This has perhaps been discussed before but I read at the http: On 24 November On 23 November That is a little slower than multithreaded one of course, but still faster than unoptimized BLAS R’s defaultgotoblxs2 all right for me.



From Wikipedia, the free encyclopedia. Wouldn’t be the first Fortran library I package.

Search everywhere only in this topic. This page was last edited on 5 Mayat For example, below code runs forever. Also “not under active development” doesn’t necessarily mean that Mr. Unicorn Meta Zoo 9: However, I cannot use many cores in parallel now. The new library includes the following features: The changes in this final version target new architecture features in microprocessors and interprocessor communication techniques; also, NUMA controls enhance multi-threaded execution of BLAS routines on node.

Here is the output from an R session which was initially restricted to run on a single core: Configurations for hardware of new platforms Incorporates features of new ISAs Instruction Set Architecture A single binary can include multiple architecture components that goroblas2 dynamically detected for binary distributions Numa controls are implemented to assure best gotoblaa2 affinity and memory policy Web Site http: Floating point Numerical stability.

It has increased the speed of some applications by as much as 50 percent. Thanks a lot in advance.

Moving from GotoBLAS2 to Intel MKL

I’m resigning as a moderator from all Stack Gotoblsa2 sites, effective today. While Goto BLAS uses performance-enhancing cache management techniques similar to other standard BLAS routines, it is able to achieve superior performance on a broad spectrum of supercomputing architectures by decreasing computing overhead caused by TLB Translation Look-aside Buffer table misses, an issue that results in significant performance degradation but is generally not addressed by other BLAS routines.


Simpler bugs may be simple to fix.
