1) Message boards : Project Staging Area : AVX build of pfgw (Message 51396)
Posted 2107 days ago by Robert47
On an AMD FX-4100 Bulldozer using Windows 7 SP1, both 32 bit and 64 bit pfgw 3.6.2 fail with "error 1002 initializing FFT code".

Are you certain that it is a build that is linked with gwnum v27.4?


I'm certain. It solves the non-SSE4 bug, and contains the version number 27.4 near the end of the file.

Whatever was changed in 27.4, it didn't fix the Bulldozer problem.


George told me that it should be fixed. What problem are you seeing with v27.4?


Every test fails with "Fatal error at setup : Number sent to gwsetup is too large for the FFTs to handle."

The 64 bit version of LLR is faster on my computer than the 32 bit version of LLR. How come?


64 bit programs have access to eight more SSE (and integer) registers than 32 bit programs do.

Still no joy on Bulldozer.

The line
geneferexe=geneferCUDA-boinc-windows
should end in .exe

Also, PPSEhigh has been completed.

my AMD Buldozder is definitely NO Core 2 processor :))

It is also not like any previous AMD processors.
