I need compute some **polynomials using giant integer with power of numbers perhaps. I found GMP library can do this in user mode. How about in kernel? Is there any existing codes? Or, I should keep the computation in user mode and use netlink to let kernel pass the task to application for computing and wait for result asynchronously. But I worry about efficience by using this method. Does it cause mode switch frequently, even on multi-core cpu chip? -------------- next part -------------- An HTML attachment was scrubbed...
