1237.0. "dfav, kap and parallel decomposition?" by CSC32::J_HENSON (Don't get even, get ahead!) Thu Mar 20 1997 11:38
I need some clarification on Fortran/Alpha/OpenVMS' capabilities for
parallel decomposition on SMP machines.
My understanding is that Digital Fortran (F90 and F77) does not
provide full SMP capabilities on OpenVMS Alpha systems. That is, it is
not capable of doing parallel decomposition or whatever is needed
to take full advantage of multi-processor smp systems. Is this
correct?
If so, what about Kap fortran. Per the spd, it does this for Digital
Fortran, but I'm not confident that the spd I just checked is current.
For instance, it makes no mention of Fortran 90. Is there a version
of Kap Fortran that performs parallel decomposition for f90? If
not, are there any plans to provide one?
Is there anything I'm overlooking here? My customer is interested
primarily in high performance fortran solutions for OpenVMS Alpha
systems.

| Your understanding is correct.
KAP Fortran 90 for OpenVMS is scheduled for release later this year,
as I understand it. The person to talk to about this is Karen Degregory
(HPCGRP::DEGREGORY). KF90 will support the same sort of parallelism that
KAP for DEC Fortran (77) does today.

| Thanks. I'll check with Karen.
