Does anyone have any views on whether this might be of any use or interest to the humble scientific Fortran user ?

Does Silverfrost itself intend to participate?

It certainly looks interesting

Agree. All topics are from the top. Organizers seems are really smart. They should consider this in other places in the world

I have booked. It clashes with another conference which I had been planning to attend, but this one seems more interesting!

As a comment or request for future development I'd like to Silverfrost to look at "NetCDF and HDF5 scientific file formats for data sharing in Fortran". Reading and writing directly into HDF5 compressed files will become an important topic with 64bit computing with its TBytes of I/O data

If not the Unicode text fonts used in open source PlPlot i'd possibly looked at it as a substitution of our ugly, buggy, crappy, dead Simpleplot in %pl. The package is not abandoned like many many others, its 3D plotting capabilities look nice, and since it is open-source the users can modify it and would never stuck in the no-go situation like with Simpleplot

I would certainly agree about HDF5. Am currently in early stages of a 4-year project that will generate terabytes of data, and frankly worried about handling such data volumes efficiently!

I agree, Dan, about improving the graphics options. I don't use Simpleplot, and have mostly coded my own 2D and 3D graphics including SVG and VRML export interfaces, but it would be nice to stop banging my head against various brick walls!

I have made a note of Dan's request.

Simfit provides some 3D drawing facilities, see FTN95 help->Win32 platform->ClearWin+->SIMFIT->Simfit plotting styles. (The images don't show up for me when using the online help so you may need to open FTN95.chm to see them.)

SVG file output is available with ClearWin+. Documentation will be provided in the next release. Let me know if you want the information now.

Paul - thanks for the news about SVG export. Useful, as it's likely to be more general than my own, which was limited to just the functionality I needed at the time. Will take a look at the SIMFIT graphics, thx for the reminder!

One other simple question (commercial rather than technical). About to buy the upgrade, but there doesn't seem to be any "1yr updates" option as there is with a new purchase. Does it come with or without updates?

The upgrade doesn't come with updates. If you would like to buy an upgrade with updates then we can send you a quote.

What's the situation wrt 64bit version and the pricing strategy ?
Is 64bit & 32 bt included in the FTN95 package ?
I see no mention of it at all on the 'Buy Me Now' page

Oh and 1yr updates seems to be a bit surplus to requirements as for the last years or so the updates have been every 'just over 1 yr' so presumeably buyers wouldn't qualify for an updated version !?

The 64-bit version is now included in FTN95. I have amended the description to reflect this.

It did take quite a bit longer to finish the 64-bit compiler than we thought it would. Quite a bit longer. Anyone who bought 7.20 with a year of updates is entitled to 8.00. Now we have a 64-bit compiler updates will be more regular.

and I would like to say thanks for this 64 bit version. I have found it very robust for the 64 bit codes I have been testing and the ease of getting more memory for the clearwin+ applications has been great.
I have also been beta testing the vector routines and find then a good addition for performance. I hope they can be finalised soon.
I hope others find it similar.

John

I have now downloaded all the documents associated with this workshop (links are all here: http://www.nag.co.uk/content/fortran-modernization-workshop). One of them is a comparison of compilers - they compare features of 9 different compilers but Silverfrost is not one of them. The list was prepared by Polyhedron Solutions, who at one time actually sold the Salford/Silverfrost compiler. Maybe worth asking them to extend the list ?

One other question (maybe asked and answered before) - any current plans to develop Fortran 2003 or 2008 versions of the Silverfrost compiler?

The Polyhedron benchmarks are no longer so prominent on their website, but after a search I see that FTN95 v 7.20 has been used on a 64 bit version of Windows.

I imagine that using SSE etc may lead to different roundoffs between 32 and 64 bit versions of FTN95 as well as differences in performance. Has anyone run the Polyhedron benchmarks to compare 32 and 64 bit versions of FTN95?

I don't think that it is useful to do so yet.

The Polyhedron performance benchmarks emphasize FPU performance. The 64-bit compiler does not support /opt yet, and the 32-bit compiler can only generate x87 instructions.

The Polyhedron diagnostics benchmarks can only be run with the 32-bit FTN95 compiler, since the 64-bit compiler does not yet support /undef, etc. The results for the 32-bit compiler are posted on the Polyhedron/AdeptScience/Fortran.uk pages.
