Why I cannot stand PGI.

posted Nov 2, 2010, 8:11 AM by Jeongnim Kim

I tried to give PGI compilers another chance but they really make it hard.

What C++ compiler does not have std::abs(double)? Apparently, PGI doesn't.

        more than one instance of overloaded function "std::abs" matches the
          argument list:
            function "abs(int)"
            function "std::abs(long)"
            function "std::abs(long double)"
            argument types are: (double)

qmcpack-doc project

While I'm not using eclipse as my development tool, I see a lot of potential of eclipse for HPC community. Inspired by the eclipse PTP (Parallel Tools Platform, http://www.eclipse.org/ptp/) development, I started a plugin project for QMCPACK document  http://code.google.com/p/qmcpack-doc/.

Changed default energy estimator

When no estimator is defined in a qmc section, LocalEnergyEstimator using ascii data format is used.

Dealing with input problems

posted Feb 20, 2010, 5:28 AM by Jeongnim Kim

Ken's summary of the discussion on Feb/19.

1)  Add a "wizard" utility to wfconv that will generate XML input with
all possible parameters with reasonable defaults.
2)  Fix as much as possible within QMCPACK itself, including aborting
on inconsistent data, parameters
    outside the allowed range, etc.
3)  Tightening up the parsing of attributes and parameters to balk at
unrecognized parameters.
4)  Introducing a "help" utility which gives possible parameters and
attributes for elements.
5)  Removing case sensitivity or agree on case conventions.
