about computer architecture questions(parallel programming)

Your company just bought a new quad-core Intel Itanium 9340 processor and you have been tasked with optimizing your software for this processor. You will run two applications on this processor, but the resource requirements are not equal. The first application needs 65% of the resources and the other only 35% of the resources. Given that 70% of the first application is parallelizable, how much speedup would you achieve with that application if run in isolation? Given that 80% of the second application is parallelizable, how much speedup would this application observe if run in isolation? This time you are running both applications. Given that 70% of the first application is parallelizable, how much overall system speedup would you observe if you parallelized it, but not the second application? How much overall system speedup would you achieve if you parallelized both applications, given that 70% of the first application is parallelizable and that 80% of the second application is parallelizable?
