Thanks.
I appreciate your working to make this happen. No pressure from me on
time. I am blessed that you are contributing this to the community and
that I can benefit from your labors. At your convenience.
I look forward to using Smallapack when available. I am thrilled to be
able to stay with Pharo and not have to use Python/Numpy. :)
Thanks.

Hi Jimmie,
The Metacello Configuration is not ready for Pharo7.
I have succeeded in loading Smallapack yesterday without Metacello,
and could run some of the tests.
I had to modify a few methods because of Pharo refactorings, and there
is still some work to make it fully operational.
When ready, I'll update the Metacello configuration and keep you informed.

When I attempt to install via Metacello in Pharo 7, I get the
following warning.
This package depends on the following classes:
Parser
MessageAsTempNode
Compiler
MessageNode
I do not know how to proceed from there. Any help greatly appreciated.
Thanks.

Hi,
I recommand inquiring about Smallapack, the Smalltalk interface
to LAPACK, on squeaksource.com <http://squeaksource.com> or
github. You'll get the speed of numpy. There is a Metacello
configuration. I have not checked the port on current
Pharo, but I can reactivate if there is some interest.

I just recently discovered FloatArray by accident.
I was close to having to use Python/Numpy due to considerable
performance differences. Performance is very important.
In one of my test using a 212000 item array of floats and
doing a sum on
each iteration through the array Pharo was taking 17 minutes
verses
Python/Numpy taking 20 seconds. Using FloatArray closes the
gap to 40
seconds. That is acceptable.
However when looking at the FloatArray comment it says it
uses 32bit
floats. I need 64bit. I don't even know where to look to
create 64bit
FloatArrays. I am surprised that they didn't get converted
when moving
to 64bit Pharo.
Would I need to change VM source? Compile a new VM and create
image side
classes? I have not messed with VM in years. I do not know
where the
FloatArray plugin would be.
Any pointers would be a great help. If this needs to be on
the vm-dev
list I can move it there.
Thanks.
Jimmie
