Understanding CUDA grid dimensions, block dimensions and threads organization (simple explanation) [
...uted by a multiprocessing unit.
The threads of a block can be indentified (indexed) using 1Dimension(x), 2Dimensions (x,y) or 3Dim indexes (x,y,z) but in any case xyz <= 768 for our example (other restrictions apply to x,y,z, see the guide and your device capability).
Obviously, if you need more...
What is the difference between a schema and a table and a database?
... of which has the attributes defined by the schema. Tables might also have indexes on them to aid in looking up values on certain columns.
A database is, formally, any collection of data. In this context, the database would be a collection of tables. A DBMS (Database Management System) is the softw...
Why does the month argument range from 0 to 11 in JavaScript's Date constructor?
...g., { "first", "second", "third", ..., "twenty-seventh", ... }) and try to index it by tm_mday. Then again, maybe they just saw the absolute utility in making off by one errors a regular occurrence.

Java: Best way to iterate through a Collection (here ArrayList)

The first one is useful when you need the index of the element as well. This is basically equivalent to the other two variants for ArrayLists, but will be really slow if you use a LinkedList.

How does python numpy.where() work?
...f True/False values, not a single value.
Furthermore, numpy arrays can be indexed by boolean arrays. E.g. x[x>5] yields [6 7 8], in this case.
Honestly, it's fairly rare that you actually need numpy.where but it just returns the indicies where a boolean array is True. Usually you can do what y...
When are C++ macros beneficial? [closed]
...ode fragments. Thus you can define a foreach macro:
#define foreach(list, index) for(index = 0; index < list.size(); index++)
And use it as thus:
foreach(cookies, i)
printf("Cookie: %s", cookies[i]);
Since C++11, this is superseded by the range-based for loop.
