Re: [Bug-apl] errors in latest SVN

[Peter Teeson]

Hi Jürgen:

I did a locate pthread* and there are only 3 .h files that show up for OS X 10.8 and 10.9 in the SDKs. 

OS X pthread*.h files.zip
Description: Zip archive

I happen to be coding in APL something that would greatly benefit from parallel capability.

My machine only has 2 x 2.66 Quad-Core Intel Nehalem  processors and each core can run 2 threads.

But most of the time most of the cores are idle.

Except in my case with the APL solution to my problem because it uses fairly deep recursion.

My thinking is that the ¨ (each) primitive would be a candidate for trying out a parallel approach.

Of course given an APL capability for parallelism one could perhaps consider a different algorithm.

(Historical note: At IPSA when we had a dual processor IBM Model 158 we did experiment with co-routines.)

Hi Peter,

fixed in SVN 478.

Looks like your box is lacking some functions like pthread_getaffinity_np() (or they have different argument types).
This could become a problem for parallel APL later, so maybe you want to grep -r  for them in /usr/include or find
out how core affinities are set on your box.
