2014   PyOperators 0.13

What’s new ?

• Python 3 support
• add settingerr context manager to contextually set error behaviour
• add environment variables PYOPERATORS_NO_MPI (to prevent importing mpi4py on supercomputers such as NERSC’s edison to avoid crashes on login nodes), PYOPERATORS_GC_NBYTES_THRESHOLD, PYOPERATORS_MEMORY_ALIGNMENT, PYOPERATORS_MEMORY_TOLERANCE and PYOPERATORS_VERBOSE (see config.py file)
• add helpers last, last_is_not, ilast and ilast_is_not, split
• improved ProxyOperator: operators in a proxy group may have different shapes, and can access the operator’s attributes
• Return algorithm instance in pcg ’s output
• add pool_threading context manager
• add MPI rank in strinfo
• in iterative algorithms, silence MPI processes with rank>0
• add timers to measure the time spent in Operator’s __call__ method and in MPI operations

API changes, deprecations:

• rename openmp_num_threads -> omp_num_threads
• deprecate distribute and distribute_slice
• change isclassattr calling sequence

Under the hood:

• common superclass for DiagonalOperator, DiagonalNumexprOperator and MaskOperator
• add Cartcomm communicator and Comm.Create_cart method in fake_mpi module
• morph MPIDistributionIdentityOperator into IdentityOperator is communicator size is 1
• allow implicit shape SparseBase subclasss
• update for scipy 0.14
• new decorator deprecated
