Fwd: Re: square, naca results

by Islam El Salawi

Hallo Andreas, thanks for your fast respond. First of all I still receive unsatisfactionary results, no matter if I watch them with paraview or visit(axial velocity doesn't become null at the noslip boundary). What about the warnings I get(I sent to you last time)? Are they supposed to appear by running the square.py or naca.py example? Secondly, trying to run hedge with cuda by writing out silo, I get an error: Traceback (most recent call last): File "square-neu.py", line 304, in <module> main() File "square-neu.py", line 166, in main tune_for=op.op_template()) File "/home/elsalawi/src/hedge/hedge/backends/__init__.py", line 120, in make_discretization return self.discr_class(mesh_data, *args, **kwargs) File "/home/elsalawi/src/hedge/hedge/backends/cuda/__init__.py", line 489, in __init__ overall_plans = list(generate_overall_plans()) File "/home/elsalawi/src/hedge/hedge/backends/cuda/__init__.py", line 456, in generate_overall_plans flux_plan, flux_time = fluxgather.make_plan(self, given, my_tune_for) File "/home/elsalawi/src/hedge/hedge/backends/cuda/fluxgather.py", line 311, in make_plan debug_flags=discr.debug) File "/home/elsalawi/src/hedge/hedge/backends/cuda/plan.py", line 58, in optimize_plan plans = [p for p in plan_generator() if p.invalid_reason() is None] File "/home/elsalawi/src/hedge/hedge/backends/cuda/fluxgather.py", line 287, in generate_valid_plans mbs_per_block*given.microblock.elements)) File "/home/elsalawi/src/hedge/hedge/backends/cuda/__init__.py", line 297, in _get_partition_data max_block_size) File "/home/elsalawi/src/hedge/hedge/backends/cuda/__init__.py", line 211, in make_gpu_partition_metis adjgraph, vweights=[1000]*len(adjgraph)) File "/home/elsalawi/src/env/lib/python2.6/site-packages/PyMetis-0.91.1-py2.6-linux-x86_64.egg/pymetis/__init__.py", line 30, in part_graph from pymetis._internal import part_graph ImportError: /home/elsalawi/src/env/lib/python2.6/site-packages/PyMetis-0.91.1-py2.6-linux-x86_64.egg/pymetis/_internal.so: undefined symbol: regerrorA ------------------------------------------------------------------- PyCUDA ERROR: The context stack was not empty upon module cleanup. ------------------------------------------------------------------- A context was still active when the context stack was being cleaned up. At this point in our execution, CUDA may already have been deinitialized, so there is no way we can finish cleanly. The program will be aborted now.

This problem is already posted in the pycuda mailing list, though it couldn't help me out solve my problem. Maybe you have an idea? Is there any trick to compile silo? I followed the instructions introduced on scicomp. If you need any more information, just give me a sign.

Attribute Error on Staging: 'int' object has no attribute 'shape'

by Daniel Gempesaw

Hi, I'm encountering a strange error on the staging branch of hedge. I created a new virtualenv with distribute and no-site-packages and made a new clean install according to the wiki instructions in case it was something strange on my side, and I got the same error again. Checking out my local copy of the master branch and doing setup.py install makes the error go away. Traceback (most recent call last): File "shearflow.py", line 198, in <module> main() File "shearflow.py", line 116, in main rhs(0, fields) File "shearflow.py", line 111, in rhs ode_rhs, speed = navierstokes_ex(t, q) File > "/home/daniel/cookie/src/env/lib/python2.6/site-packages/hedge-0.91-py2.6-linux-i686.egg/hedge/models/gas_dynamics/__init__.py", > line 841, in rhs **extra_kwargs File > "/home/daniel/cookie/src/env/lib/python2.6/site-packages/hedge-0.91-py2.6-linux-i686.egg/hedge/backends/jit/__init__.py", > line 485, in __call__ self.discr.exec_mapper_class(context, self)) File > "/home/daniel/cookie/src/env/lib/python2.6/site-packages/hedge-0.91-py2.6-linux-i686.egg/hedge/compiler.py", > line 492, in execute return self.execute_dynamic(exec_mapper, pre_assign_check) File > "/home/daniel/cookie/src/env/lib/python2.6/site-packages/hedge-0.91-py2.6-linux-i686.egg/hedge/compiler.py", > line 447, in execute_dynamic insn.get_executor_method(exec_mapper)(insn) File > "/home/daniel/cookie/src/env/lib/python2.6/site-packages/hedge-0.91-py2.6-linux-i686.egg/hedge/backends/jit/__init__.py", > line 54, in exec_vector_expr_assign compiled(self, stats_callback)), [] File > "/home/daniel/cookie/src/env/lib/python2.6/site-packages/hedge-0.91-py2.6-linux-i686.egg/hedge/backends/jit/vector_expr.py", > line 53, in __call__ shape = single_valued(vec.shape for vec in vectors) File "/home/daniel/cookie/src/pytools/pytools/__init__.py", line 292, in > single_valued assert others_same() File "/home/daniel/cookie/src/pytools/pytools/__init__.py", line 288, in > others_same for other_item in it: File > "/home/daniel/cookie/src/env/lib/python2.6/site-packages/hedge-0.91-py2.6-linux-i686.egg/hedge/backends/jit/vector_expr.py", > line 53, in <genexpr> shape = single_valued(vec.shape for vec in vectors) *AttributeError: 'int' object has no attribute 'shape'* Is this error message familiar to anyone? I guess if no one recognizes the error I'll try to checkout older commits of staging until I find one that works. Thanks! Daniel Gempesaw
