From bug-octave-request at bevo dot che dot wisc dot edu Wed Apr 29 18:32:28 1998 Subject: Digital Parallel Mathg Library From: Franc Carter To: bug-octave at bevo dot che dot wisc dot edu Date: Thu, 30 Apr 1998 09:30:56 +1000 In an attempt to get Octave to use the multiple CPU's on our Dec Alpha-8400 I changed the SPECIAL_MATH_LIB variable on line 134 of the Makeconf file from -ldxml to -ldxmlp so that it would use the threaded version of the maths libraries. When I multiply two matricies together Octave usess all free CPU time while it is waiting at the prompt (it appears to work however). i.e octave:1> a=rand(10,10); octave:2> b=rand(10,10); octave:3> c=a*b; octave:4> Version: Octave-2.0.11 OS: Digital unix Version 4.0B Extend Maths Library Version: 3.3 Compiler: gcc version 2.7.2.3 Digital f77 version 5.0 Has anybody else tried to parallelize Octave ? Is what I have done reasonable ? -- Franc Carter MEMLab, University of Sydney Ph: 61-2-9351-7819 Fax: 9351-6461
