I am encountering segfaults when checking the lme4 package on an Athlon64 system if I use the acml blas. R was built as a 64-bit application using the GCC 4.0.3 compiler suite including gfortran. The version of acml is 3.5.0 gfortran64.
I do not encounter the segfaults when I compile R with R's built-in BLAS. The errors occur in the first example in lme4 in a call to lmer. It looks like they would occur in any call to lmer. Running under the debugger shows that the segfault occurs in a call to dtrsm (a level-3 BLAS routine to solve a triangular system of equations) that is called from within a cholmod (sparse matrix library) routine. Has anyone succeeded in running R CMD check on the lme4 package with accelerated BLAS? I'm trying to pin down is this occurs only with ACML or also with Atlas and/or Goto's BLAS. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
