- for example,
string buffer = ...;
SubStrings<string> split;
{
auto colon = buffer.find(':');
if (colon != std::string::npos)
{
split = stringOps::splitSpace(buffer, colon+1);
}
}
Not really possible with a substr() since that would create a new
temporary which then disappears. Similarly awkward to split and
then scan for the ':' to decide how many to discard.
ENH: add pop_front() and pop_back() methods to SubStrings
- the content is trivial enough (a pair of iterators) and the total
number of elements is usually reasonable short so that removal of
elements is inexpensive
For example,
string buffer = ...;
auto split = stringOps::splitSpace(buffer);
if (!split.empty() && split[0].str() == "face")
{
split.pop_front();
}
Test that -ioRanks selections perform as expected and that sub-rank selection is also doing the correct thing. For example, mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks host mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '(0 3 14)' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks 14,15,2,0,10,15,0,0,0, mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,10' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,11' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,14' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,15' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,12,115' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3,10,12,115' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks host -pick '1,2,3,4' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -pick '2,4,6,8' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,3' -pick '2,4,6,8' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,4' -pick '2,4,6,8' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,6' -pick '2,4,6,8' mpirun -np 10 --oversubscribe Test-fileHandler-ranks1 -parallel -ioRanks '0,6' -pick '2,4,6,8'
