Context: Options with values are not properly parsed.
If the value is not set, a bug makes appear that 0 was
provided.
This patch fixes options parsing (issue #337). An error
is reported if 'backend.option=' argument is provided.
* Basic support for memory allocation on GPU using CUDA unified memory. Partially addressing #284. IOR support completed.
* Support for GPU alloc in MDTest and MD-Workbench
* Option: support repeated parsing of same option (allows option sharing across modules).
* Checks for gpuDirect
* Integrate gpuDirect options and basic hooks, more testing to be done.
* POSIX: basic gpuDirect implementation working with fake-gpudirect library.
* CUDA allow setting of DeviceID for IOR (not yet MDTest).
* CUDA/GPUDirect Support --with-X=<path>
* Bugfix in option parser for flags that are part of an argument for an option, e.g., -O=1, if 1 is a flag it is wrongly assumed to be a flag.
On previous versions of IOR (and most Linux CLI applications in general)
multiple flags can be combined such as -vvv to get verbose=3 rather than
having to specify each separately as -v -v -v. This patch fixes this behavior.
It also fixes issues around handling of the verbose flag where the
output would never be printed as we were comparing verbose < VERBOSE_0
where verbose defaults to 0 and can only increase.
The parser now supports concurrent parsing of all plugin options.
Moved HDF5 collective_md option into the backend as an example.
Example: ./src/ior -a dummy --dummy.delay-xfer=50000
