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.
In reply to this post by tmacchant. On Tue, Nov 23, at Regards Tatsuro What is the No. Views Read Edit View history. Still would not expect the code to ‘run forever’, just slower than the for one. Now I have an urge to package it for Debian.
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.
