Dear All,

is &-symbol use GPUs ?

Best Regards,

The Dyalog interpreter does not currently make use of GPUs.

The interpreter does use threads for a limited number of scalar dyadic functions - there's more info in the following post: viewtopic.php?f=30&t=574&p=2206&hilit=1111#p2206

We have introduce isolates, which allow you to parallelise tasks by partitioning the data and sharing the load across multiple APL processes - which themselves can be spread across multiple physical or virtual machines. The isolate documentation can be found at http://docs.dyalog.com/16.0/Parallel%20 ... atures.pdf.

Aaron Hsu is working on the Co-dfns compiler which does use GPUs. There's a link to his talk at Dyalog '17 on https://www.dyalog.com/user-meetings/dyalog17.htm, and he spoke at previous user meetings too. It is still experimental, but it may be of interest to you.

Dear Andy,
Great thanks for your time.

isolates are very good idea. but the calculus charge is wear by the same processor.
GPU's add a new processor (sometimes, just a slice).

interesting with Aaron hsu, and Martin Elsman (University of Copenhagen)do also a great job.
