Perhaps you should try some spelling variations:
concurrent processes » concurrent processing, concurrent programs, concepts processes
information pge » information pre, information pt, information put
pge concurrent » ce concurrent, use concurrent, large concurrent
arrays probing » array probing, rays probing, arrays producing
array forming » array arcing, array fermi, array formats

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: information pge concurrent processes ((((array forming) or (array format))) or (arrays probing))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information pge concurrent processes ((((array forming) OR (array format))) OR (arrays probing)).
• Adding a wildcard symbol may retrieve word variants: information pge concurrent processes ((((array forming) or (array format))) or (arrays probing))*.
