Hi

Solving PDE, the stencil possibility in arbb is useful. My question is about the vectorization/parallelization of the boundary conditions where the stencil doesn't apply.

For example i use the stencil in that way :

// first the stencil

// ********************

Hi I am using dense vector and i try to fill row or columns without _for nest in order to get parallelization: For exemple is it possible to fill a row or column with a given value : dense a; a(0, all) = val ; // all for all elements of row 0 If yes is it possible for a section : a(0,[1:3])= val ; // This possibility is available in all C++ libraries i use (eigen, blitz++). Thank you very much

Hi I developped a kernel with ARBB for solving Partial Differentiel Equation in 2D with stencil. Everything is fine with the emulator (ARBB_EMULATE=1)though being very slow comparing with a pure C++ version. Without the emulator, even withARBB_OPT_LEVL=O0, the code runs a long time ending with a Low level optimization (LLO) got the exceptions: ILLEGAL_MEM_OP: Access the illegal memory address => Accessing not mapped address [0x50] at IP[0x7fd6736ffad5]. Failed! terminate called after throwing an instance of 'arbb_2::internal_error'

Hi On simple another example i still get a "what(): zero types captured" although an arrb data is a member. // using bool so that the capture will recall the function behavior
class PayOffSimple1 { private : arbb::f64 strike ; bool bVendeur; public : PayOffSimple1() : strike(0.),bVendeur(true){} PayOffSimple1( arbb::f64 strike_, bool bVendeur_):strike(strike_),bVendeur(bVendeur_){} arbb::f64 operator()( const arbb::f64 & x) const { if (bVendeur) { return arbb::max(arbb::exp(x)-strike,0.); } return -arbb::max(arbb::exp(x)-strike,0.); } };
