Hi Sergey,

Windows and linux might be different here. On linux we compile SDE asking the compiler to insert SSE3 instructions. On windows, we only use SSE2 as a target.

In theory, SDE could run on a P4 without SSE3 and emulate the SSE3 instructions. I wrote SDE partly because I had PIIIs and had to handle P4 binaries withe SSE3, but that was a long time ago now.

I was not aware there were P4's without SSE3. SDE is built upon Pin and pin has some P4-requirements but your chip has the required features for Pin (CX8, FXSR, CMOV, SSE2).

I guess you tried it and it did not work? on Linux?

Regards,

Mark

[SergeyK] I didn't try yet. I simply wanted to get some information ifSSE3 could be supported by
SDEon Windows XP SP3?

Could you verify ifSSE3 emulationis supported andworking?

Best regards,
Sergey

It will take me a few days to find and get access to a P4 running windows. Hopefully it is easy enough for you to download SDE and try it yourself. Should work.

[SergeyK] I can't follow that path. I'd like to know in advanceif it supports SSE3. If it does than I
could schedule some time for all the rest tests.

Mark,

The SDE is not a new software product and it should have some docswith a list of supported features.
Also, you worked on the project and had, or maybe still have,full access to thesource codes. Could you
simply verify ifthe SDEsupports SSE3?

[MarkC_Intel]

SDE supports emulation of SSE3.

On windows the SDE program itself uses SSE2 instructions.

On linux, the SDE program actually uses SSE3 occasionally.

We generally tell people that they need a P4 host to run it, but in the linux case, the P4 host would have to have SSE3.
