class hysop.backend.device.codegen.symbolic.expr.OpenClBool(expr)[source]

Bases: TypedExpr

Convert a scalar boolean condition (ie. a int in OpenCL) to a compatible vector boolean condition (ie. all bits set) prior to vectorization. Also force min integer rank.

doprint(expr, terminate=True)[source]

Print the expression as code.

Parameters:

  • expr (Expression) – The expression to be printed.

  • assign_to (Symbol, string, MatrixSymbol, list of strings or Symbols (optional)) – If provided, the printed code will set the expression to a variable or multiple variables with the name or names given in assign_to.

Symbols are identified by name and assumptions:

>>> from sympy import Symbol
>>> Symbol("x") == Symbol("x")

True >>> Symbol(“x”, real=True) == Symbol(“x”, real=False) False
