These new versions have support for the Intel AVX 256bit SSE extensions. They generate compatible results, so there's no need to reset the project or abort workunits. Unless you have a sandybridge processor and want to see if AVX works. I have no way to test that code here.

Why is setigraphics_6.94_windows_intelx86.exe so big at 53.73Mb? when setigraphics_6.91_windows_intelx86.exe was only 1.01Mb?

About new 32bit linux version

Doing some standalone testing some behaviour is not so good. It seems there are no "state.sah"-files created/written and runtime is overly long when compared to v6.93 (runtime ca. 8 minutes). Stopped the test after one hour without finishing.
Edit:
Seems to work normal under BOINC.

Answering to myself after some wus are done (or should be done) :
No, it is not. Picking up and continueing a wu, that was started by an older version (6.91, 6.92 or 6.93), led to, v6.94 finishes the wu normal while updating the "state.sah" properly.
But, starting a new wu, there is no real progressing. After one hour under boinc there is only 0.018% progress shown in BOINC manager. At that speed a wu at AR=1.24 would take more than 230 days.

Although setigraphics_6.94_windows_intelx86.exe took nearly 5 hours of download time on my dial-up connection, the file did pass its signature check. Checking the top computers list shows that some have completed tasks with the Windows 6.94 build, and BOINC won't start those tasks until all required files have been successfully downloaded.

Obviously a 53 MB file won't do for main, with many active hosts there it would really impact the download of work too much. With fewer than 2000 active Windows hosts here, my rough calculations suggest it may be using about 10% of the download bandwidth which is unfortunate but not disastrous.
                                                                    Joe

setigraphics_6.94_windows_intelx86.exe passed it's check here too, i've put it on a USB stick and copied it into my Beta project folder on some of my other hosts, so i don't have to download it again,

Done a offline benchrun on the 6.94 Windows app over at Lunatics on the shortened v7 test Wu's, there's a nice speedup even on non AVX CPU's,

I'm trying to decided whether to deprecate the windows version. The fftw dll didn't get checked into the app_version table, and I don't think I can successfully add it after the fact. If the windows version is working for you, it's probably because you still have the dll in your boinc project direction.

Eventually it will fail for someone.

Regarding file sizes. The windows exes will get stripped and compressed before it's released to the main project. It's also possible that statically linked versions of some dlls are getting linked in rather than the dynamic versions.

Eric, thank you for the explanation. Now I know why the 2 WUs I tried on my Sandy Bridge (I7-2820QM) laptop both terminated immediately with an exit code of C0000135.

Since reading your post, I have manually downloaded the libfftw3f-3-1-1a_upx.dll file and modified an app_info.xml file I found in an earlier post (Thank you, Sutaru.) to run the setiathome_6.94_windows_intelx86.exe using Anonymous Platform.

I have seen the first WU finish early due to a -9 result_overflow, but at least WUs are now running. Several more have now finished and are awaiting validation.

If you decide to proceed with the creation of x86_64 versions of the programs kindly send them in my direction.

You can get 6.94 to work by downloading libfftw3f-3-1-1a_upx.dll and dropping the file in your Beta project folder,

I'd try redownloading the dll, overwrite the last one, you could also try restarting Boinc and Windows, (0xc000007b) and (0xc0000135) are both initialization problems,
and make sure the dll is in your Beta project directory, that should be on your host C:\ProgramData\BOINC\projects\setiweb.ssl.berkeley.edu_beta\

Boinc debug flags won't help, this is an app problem,

Thanks Claggy, that worked. The dll I downloaded before was 260 kB, and the new one is 439 kB.
