Hi. I am doing some complex computations using c, c++, matlab, python. It is very slow on a conventional PC. I heard, there is a way to do scientific computations remotely. Such that I could sort of get an access to the remote advanced PC, and perform computation remotely there. And then download the results. Could you please advice some web links where I can do such cloud computations? Is there a possibility to try it for free? Thank you.
