Maho On thinking about it, it was the wrong question to ask as the structure is such that C++ types will not have equivalents in FORTRAN. The problem is that I want to adapt some code which is in FORTRAN so I am going to have to find some way to interface the two. I am working with MAGMA (LAPACK for GPGPUs see http://icl.cs.utk.edu/magma/index.html) and I have to interface FORTRAN to C++ there. Thank you John Dr John P.

Hi Fletcher, Oh you're developing MAGMA! Great. It is very fast on C2050. Anyway, interface to FORTRAN77 would be impossible, but FORTRAN90 or 95 might be possible. Which MP library do you want to use? GMP, MPFR, QD? thanks, Nakata Maho From: "Fletcher, John P" <j.p...@as...> Subject: [Mplapack-devel] FW: Fortran examples Date: Thu, 31 Mar 2011 13:05:04 +0100 > Maho > > On thinking about it, it was the wrong question to ask as the structure is such that C++ types will not have equivalents in FORTRAN.

Goto san kindly told me that even though logical core is counted as eight, GotoBLAS2 enumerate the number of physical core and set it as the number of threads. thanks -- Nakata Maho http://accc.riken.jp/maho/ , JA OOO http://ja.openoffice.org/ http://blog.goo.ne.jp/nakatamaho/ ,GPG: http://accc.riken.jp/maho/maho.pgp.txt |

Nakata Maho I was looking at the choice last night. I think I am going to use mpfr (mpreal C++ interface) and mpcomplex. I needed to reorder the libraries, -lmpc before -lmpfr as a test case was not linking properly. I had copied MPFRLIBS in the examples/mlapack Makefile. There does not seem to be an operator<< in mcomplex but it should not be much work for me to make one. I am using gfortran, so plan to follow the MAGMA style to make an interface, but I will start with some C++ examples with MPACK to get a better understanding. I am more familiar with LAPACK than MPFR. You will find I am quite active at the moment on the MAGMA forum. Are you in touch with Goto Kazusige? There is unfortunately a bug of some sort in the Nehalem version of GotoBlas2 which means that safe operation requires use of the 4 core version even on an 8 core machine. It does not look as though maintenance is being done any more on the distribution site. I don't have full details but can get them if needed. Best wishes John Fletcher Dr John P.
