Hello Nick-MMX,
Already covered. NRW is a special case that runs for 7 hours. During that 7 hours it will run simulations for seconds or minutes, depending on the speed of the CPU. Eventually all the desired ?tens? of thousands of simulations will be run for a protein.. Unless the validator function finds a simulation result far off the curve, no makeup units will be sent. The scheduler (uhh, really a different process, but I forget) will send out a new unit to continue from the end. This is not necessarily the most efficient use of our server, but we control the work units sent, so we can keep the inefficiencies from overwhelming us.

So this is one method that can be used to allow us to graciously use the widow's mite without sneering at slow CPUs. We are constantly developing different ways of running projects to meet different needs.

On top of the fixed 7 CPU hours for the RICE jobs, the HCMD2 jobs are in principle delimited to 4 hours. If not finished by then or having reached 60% of the total work in the task, it will cut off at the position underhand. The remaining positions are put into a new task for someone else to compute.

The problem with HCMD2 is that it takes a lot of work on our part to handle cut-off work units and netbooks would cut off all work units. So it is best to stick too NRW for netbooks or reconcile yourself to multi-day runs on FAAH.

Will be looking at a new notebook once the new Ix (I7, I5, I3) hyperthreaded CPU's with turboboost are out. Supposedly they use 25% of the power compared to a regular Ix comp. They have on-cpu graphics so that the cooling part of these laptops becomes a whole lot easier to implement.

Did not know until I read that, but they mentioned that some of the atoms have hyperthreading.

I thought that I had already chimed in on this one; but I cannot find that I responded.

I have a pretty original netbook: 8.9" screen, Atom N270 processor, 1 gig DRAM. My machine is an Acer 150-1635.

This machine, and probably any netbook, will do some work, just recognize its limitations :no speed, no power. I can run Rice, I can run some Leiden, Spinhenge, just look for projects with short work units.

I bought this machine to just manage one of my external hard drives of music and video, and for travel. But, no machine that cannot crunch comes into my life.

I have checked results on this machine and they are fine. There are just not a lot of them compared to my 2 Core 2 Duo machines and my I7 machine.
