'''Parallelizing

We From one of the suggested improvements in the algorithm post link. A potential improvement is changing from char& c to a const char in the for loop <syntaxhighlight lang="cpp"> for (char& c : input) { </syntaxhighlight > since char& c is not being modified. Otherwise we did not see any ~~other~~ way to parallelize ~~the algorithm~~compression.

=== Assignment 2 ===

Profiling the code shows that '''~~cudaMalloc~~memcpy''' takes up most of the time spent. Even when

there are 10 iterations, the time remains at 300 milliseconds.

As the iteration passes 25 million, we have a bit of memory leak which results in inaccurate results.
