px this is no problem for BOINC.

 

When a new windows version of BOINC is available (with reporting of AVX) i
will test it with WinXP/WinXP-64bit, and if it is reporting AVX...i will
test it with the PrimeGrid app  ;-)

feature

 

AVX needs support from operating system and according to Wikipedia the first
Windows to support AVX is 7 SP1.

Should the client report all the features that could be available and leave
it to the scheduler to decide what is safe to use or should the client
report only those features that the entire system supports?


(SSEn needs OS support as well, but since that was added in Win 95 or 98
maybe we can safely assume the support is always available.)

Subject: [boinc_dev] : BOINC (windows) doesn't report avx processor
feature

Hi all,

BOINC (windows) reports these processor features for a sandy bridge CPU
(2600k):
Processor features: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss htt tm pni
ssse3 cx16
sse4_1 sse4_2 popcnt aes syscall nx lm vmx tm2 pbe

But there is no avx entry, so PrimeGrid cannot deliver the new
GeneferAVX application to windows hosts.

Can you please add this line to hostinfo_win.cpp (e.g. line 1075)?

FEATURE_TEST(std_supported, (std_ecx & (1 << 28)), "avx ");


Regards
Wolfgang Schwieger
