Hi Eslam, Along the lines of what Jimmy mentioned about "giving things up" specifying fully versus partial tryptic really speeds up the search if that is suitable for your sample.
I would recommend talking to your IT department to see if they have any ready solutions for increasing your computing power. They may have resources available that you are not aware of. For example, I talked to the IT Dept. here and they happily set up a 12 core virtual machine that I installed TPP on. They would have done more, but ultimately they wanted to charge me a yearly fee and I decided to go the less expensive route and buy pre-owned "pizza boxes" with dual hex cores, install Ubuntu and TPP myself. These are relatively inexpensive on E-Bay for ~$500 depending on configuration. Here is one example: http://www.ebay.com/itm/HP-Proliant-DL360-G7-Server-2x-X5670-2-93GHz-HexaCore-128GB-4x-450GB-2x-power-/322197730383?hash=item4b047b344f:g:FOAAAOSwtnpXpQMR You may be able to work with such companies that sell these units to have them configured to your specs. So the above would be for just one shared memory system with 12 cores (+12 virtual cores if you config it that way since these processors support hyper theading, which may or may not speed things up. Apparently with hyper threading more isn't always better). Using Ubuntu or other Linux distros, you can set up a cluster of many of these inexpensive boxes that will work in parallel to further increase your processing power. With 5 such boxes, mentioned above, you could have a 60 core cluster for less than $3000 in hardware. Ultimately its your budget and ability to do things yourself that will determine what is best for you.
