Re: [Paraview] reducing startup time on cray

It makes sense to me too. Having said that, wouldn't it be better to go to the next step and use a frozen Python? If all of the commonly used Python modules are frozen to the build, loading them will become much faster. The solution that you are proposing only defers the cost to later. Given that

Re: [Paraview] Extents problem

Hi Greg, I tracked down the problem. It is this line: 133 sgrid-SetDimensions(count[0], count[1], count[2]); This is equivalent to sgrid-SetExtent(0, count[0]-1, 0, count[1]-1, 0, count[2]-1); which overwrites the earlier SetExtent() call. If you get rid of it, it should work fine. Best,

Hey Rich, Is this a matter of updating the VisIt bridge or the code in VisIt is old too? What are the larger runs these folks do? And what is the timeframe? We are working on ADIOS readers and that may be another option. This is where we currently plan on pushing for large scale IO needs. HDF5
