I've been a 'standard programmer' for many years but have recently moved into bioinformatics and I can see that the types of programs I need to write now are fundamentally different form what I used to write: due to the huge volume of data and amount of processing performed means I need to shift my mindset when I design programs from a 'serial' design to a 'parallel' design.
I've had a look for books on parallel computing and they are WAY too technical for what I'm looking for. I'm looking for tutorials/guidelines, not necessarily specific to bioinformatics, to make me start 'thinking in parallel' if that makes sense.
I was also wondering if there was software available where you could emulate a multi processor environment. I was thinking perhaps if I started working in a multi processor envinonment I would start thinking that way.
As a basic example I have a perl script I've been passed to work on which sends 12 millions SNPs to one function, waits patiently for this function to return and then shuttles the 12 million SNPs off somewhere else. I've never heard the term before today but this is an embarassigly parallel problem. It's crying out for parallelism (or parallelisation - see i don't even know the right words!) but I would have implemented the code in exactly the same way myself as I don't think parallel.
So really, I'm looking for books/tutorials/websites/guides to help me think parallel. I'd also value other people's insights and experiences but I'm aware that this is a vague question and that this forum appreciates questions where you can have a direct answer and not simply discuss things.
Thanks in advance for your help
