Instead of blowing against the wind, I changed my super lotto program to work on IRIX, AIX & Windows using ostringstream to convert the INTs to Strings.
First off the board was the random seeding issue. which I had implemented wrong in the first place but it did leave me wondering..
Basically the program:
Generates as many random lottery draws of 6 numbers as inputted by the user.
Adds a count of each number drawn.
Calculates the highest drawn 6 & the lowest drawn 6.
At first this was done through a loop which went through the list sequentially, but that proved to be biased towards the end numbers in the loop, so say number 1,4,5,6,7,8,10 had been drawn 100 times, number 1 would always be pushed off the list. To counter this, each number taken from the list index was also a random number, so 10 could be checked first and maybe 1 last.
Each time a random number was obtained, a new seed was created and this was my mistake.
The IRIX, AIX compile would always get stuck finding the last 2 entries in the list index whilst sorting, yet the windows always worked fine, this had me scratching my head with possible timing issues. I had a loop to delay the time for the new seed by 1 second, and yet it was never able to sort the last 2 numbers.
I changed this to produce a single seed at the beginning, all was well and I was able to remove any sleeps, pauses or loops. To speed things up further, I may remove each entry checked from the list and reduce the random number for the list index sorting.
The AIX can produce a 10,000 lotto sample in about 4 mins, as does the windows machine which is an i7 - Quite impressive I thought. The SGI (300MHz Octane2 - 1.5 GB of memory) is still running and has taken half an hour so far.
Below is the code taken from the windows machine because I'm on it right now. It's exactly the same apart from a few headers in and out.
I may do some time trials on my machines and maybe win the lotto in the process.
