Re: [Help-gsl] Floating point exception in gsl

in Alpha EV7 using cc (HP Tru64 C compiler): MPI process 21963 died from signal 8 (Floating point exception) Does anyone know how to solve it? Thanks. Additional options are needed compiling on Alpha, see the platform specific compilation notes in the INSTALL file. -- Brian Gough (GSL Maintainer

Re: [Help-gsl] Floating point exception in gsl

: GSL_IEEE_MODE=mask-all MPI process 391678 died from signal 8 (Floating point exception) Do you know why? Thanks. On Alpha the libray has to be compiled with -mieee (with GCC). For other compilers that option is probably called something else. -- Brian Gough (GSL Maintainer) Network Theory

Re: [Help-gsl] How to solve a linear equation system with left (lower) triangle matrix in gsl?

or lower triangular matrices, e.g. gsl_vector_memcpy(x, b); /* x - b */ gsl_blas_dtrsv (CblasLower, CblasNoTrans, CblasUnit, L, x;) See the documentation for more details. -- best regards, Brian Gough (GSL Maintainer) Network Theory Ltd, Publishing the GSL Manual - http
