Subject: Re: [Pdl-general] PDL 2.059 released
Hi Ed,
I've noticed very strange clutter of # line ... in PP
2.059 had problems on more recent versions of the MinGW runtime. I have now
worked around these, and released a new 2.060 which seems to work again.
Please report any problems in 2.060!
Best regards,
Ed

The IRC channel (#pdl on irc.perl.org) is a great virtual place to come and ask
questions, or just watch the GitHub messages flow by.
As usual, please give the new PDL a try and report problems.

Thanks, Zaki!

I should add: it is a known problem that older versions of clang/LLVM (at least
10.0.1 and 12.0.0, though not 12.0.5) crash when compiling the latest PDL. If
this happens for you, please upgrade your clang/LLVM.

I have now updated the PDL version, which now shows speed comparable to C, and
indeed with the pthreading it’s even faster (which isn’t fun to do in pure C,
but incredibly trivial in PDL):

Further to this, an obvious approach for e.g. “conj” is to add “PMCode” that
simply does “return $self if $self->type->real;” first, with the obvious
“topdl” bit first to setup $self.

Hi Luis,
I’ll take a look shortly (in the final stages of getting the multi-C to work).
Can you confirm whether this worked according to your expectation in 2.057?

intended development is to use OpenCL where available to
automatically translate pp_def-ed functions to use GPUs as well.
The second and third main points are intended to transform PDL into a C library
with a Perl interface, which could then be used in C programs, or via
interfaces in other
