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.
