Data generated when executing submissions (i.e., the "stdout", "stderr" streams) can have any size (OS limitations may apply). However, Sphere Engine saves only a shortened data stream of the maximum allowed stream size.
For the Sphere Engine Compilers module, the maximum stream size is 1MB for both streams.
For the Sphere Engine Problems module, the maximum stream size (per test case) is:
5kB for "stdout" stream,
1kB for "stderr" stream.
Note: The verification procedure conducted during the evaluation of the user's submission uses complete stream data.
