[M3devel] Renewed interest in Modula-3 in HP Labs

[Daniel Alejandro Benavides D.]

Hi all l
looking to support a c-backend we would need to know how much can we optimize the energy consumption of any backend CG or how long can we use M3CG in compilation time total (the result could be that we need to distribute precompiled form, see p. 7:
http://www.fdi.ucm.es/profesor/ricardo/ei2/crisis.pdf

).
This would be a rather good measure of the need of a Object code backend or not (like Gcc, or JVM one, or a translation based like Pascal first implementations were pascal manually machine coded). For instance HP had  HP3000 [1] with several measurements, as their "u-code" Interface was not open but proprietary so you couldn't get their compiler for A-L/SPL (contrary to pascal). I'm sure they have worked out in this problem as well as for newer machines (like for fpga reposition programs for VAXen and Alpha) but how much they will emulate in SW I don't know.
I write that because VAX is essentially translated to Alpha via M3CG via HW and equally in SW. I know they are producing VAX in FPGA, but don't know abut Alphas at all.
Thanks in advance

Hi all:
I see there is some products coming from HP, and others, but specially HP, claiming that provide lower consumption in data center power management.
As I see they are working in Tycoon as a Data processor (created in Germany and Europe).
As Greg Nelson wrote code for profiling the Alphas and Itanium, perhaps they are interested in work on ESC, but nevertheless Modula-3 and family languages (Quest) as Tycoon is based on them.
If I may say so, Quest was defined by its simple denotational semantics, which is the natural deduction system of Baby Modula-3 (though it lacks more than that, but you can process the language of it through the former)
Do we want to confirm that, if anyone interested in the TML - TVM please write me for any other questions or comments
Thanks in
 advance
