Hi experts!!
Im doing Monte Carlo simulations with my laptop. The papers relationated with my topic says that use CPU clusters for calculus. Does free and public clusters exists? How can I use that for run my codes writen in SAGE? (I use ubuntu 13) Can I use SAGE Cloud for that? How?
Waiting for your answers.
Thanks a lot!
Right now https://cloud.sagemath.com provides a single computer with 8 cores. From within a worksheet, you can use the @parallel decorator to run 8 computations at once (type parallel? for docs).
Depending on what you're simulating, you might benefit a lot from writing Cython code (included in cloud.sagemath), using numpy/scipy (which is in Sage), etc.
I'd be the last to put the brake on your sage enthusiasm ... and I can't answer your question on SAGE cloud usage ... so, admittedly my answer is kind of unrelated to this forum ... but if you are really up to writing scientifically competitive numerical Monte Carlo production code including - as your question suggests - parallelism, i.e. most likely code that makes use of MPI, then, to my humble understanding you may want to reconsider, if a CAS like sage is really what you want to use for that - before you get stuck. Surely you can try doing your best at using essentially the C(P)ython subset of sage including libs like mpi4py. But even then - and I have lots of examples for that - it is very very likely, that your MC code will perform poorly, to say the least, as compared to any straightforward C++ implementation.
