[hts-users:01933] Re: Fast & memory efficient HHEd clustering patch

[康世胤 <kangshiyin@xxxxxxxxx>]

hi, 

i have tried these 2 patches. the fastHHEd.patch works well, 
but the HHEd.c.patch seems not so good.

it is even slower after this patch is used on my computer.
and i find that all other programs such as HInit & HRest become slower if the -fopenmp flag is applied when compiling.

my compiler is gcc4/Fedora9

is this gcc or openmp's problem? should i use icc or something else?

The attached patch code provides additional parallelization based on OpenMP to reduce the computational time while setting the Question x Model table.  To turn on this parallelization, you need to compile it with a option for OpenMP.  For gcc (>=4.1), please use -fopenmp option.  Intel compiler also supports OpenMP (-openmp).
