Intel Visual Fortran 64-bit support

[kerryblue19]

Intel's Visual Fortran has 64-bit support right?

Also does Compaq Visual Fortran 6.6 for linux have 64-bit support?

Thanks.

Intel Visual Fortran does provide a compiler for 64-bit Windows. (Two of them, actually.) The one you are probably interested in, for "Windows XP x64", we refer to as our compiler for Intel EM64T. In version 8.1, this is a separate download from Intel Premier Support File Downloads - the installer has a name starting with "w_fce". In version 9.0, it will be bundled with the other compilers. You can get to Intel Premier Support after you have registered your compiler serial number.

The other 64-bit Windows compiler is for systems based on Intel Itanium processors which can run Windows Server 2003.

CVF has no 64-bit support (and never will.)

For best performance on Intel processors with Intel EM64T, use the /QxP option for code generation. If you want to run on AMD 64-bit processors too, use the combination of /QxW /QaxP instead.

Note that the EM64T compiler is used at the command line at present.

Steve,

I was under the impression that the PSDK from Microsoft was required for the visual interface?

Will a 64 bit AMD also compile a 32 bit version?

Can you tell me when version 9.0 will be released?

Thanks

The PSDK does not provide the visual IDE. It is command line tools and libraries only.

When Visual Studio 2005 comnes out, we will then release an update which provides integration into that version. VS 2005 (note that they have dropped ".NET" from the name) will be usable on EM64T systems and you'll be able to select which target you want to compile for.

We have three separate compilers. The 64-bit compilers do not compile for 32-bit code. But the 32-bit compiler is available for use on EM64T/AMD64 systems.

9.0 will be released in June.

I have to retract what I just said. The 32-bit compilers are currently NOT supported on EM64T systems, because Microsoft did not support VC.NET on those systems. We have new information that this situation may have changed. We will test it and if it pans out, then we will update the product to allow install of the IA-32 compiler on EM64T systems.

Sorry for the misinformation.

Steve,

I have been holding off on a purchase of IVF in hopes version 9.0 will be released soon and I was hoping to get all the capabilities including use ona 64 bit computer.

I have invested in a 64 bit computer for this reason and now I see there may not be a Visual Studio 2005 release soon that has capabilityto integrateIVF(EMT64). Nor will IVF be suitable for use with visual studio 2005at first since it sounds that Intel has to start working on that.

What are the policies on getting updates if I was to purchase now?

Can you tell me when IVF version 9.0 will be released?

What is Intel doing to integrate EMT64 into Visual Studi 2005? Is there any Beta testing involvement?

Thanks

Ken

Ken,

We expect to release version 9.0 within the next two weeks. Our policy is that you get, at no extra charge, any update or new version released within 12 months after your purchase. We license by "support date", not by version. After the initial 12 months, you can renew your support agreement at a 60% discount for an additional 12 months.

We have long ago started working on support for VS 2005 and in fact have it fully functional in-house. But Microsoft does not allow VS partners to release products based on beta varsions of VS, so we cannot offer such support until Microsoft publicly releases VS 2005 (the date for that keeps sliding into the future). If you are interested in beta testing, we would be glad to accomodate you, but the beta for that has not yet begun. Send your request to Intel Premier Support.

Yes, the EM64T compiler will be available from within the VS 2005 environment. You can sort-of fudge it from within VS.NET 2003 if you want - details are in the release notes.
