Subject: PARI/GP and parallelism
Date: Fri, 17 Jun 2022 14:35:11 +0200	[thread overview]
Message-ID: <Yqx0/8lBaANe1esC@jurong> (raw)

Hello,

PARI/GP ("guix edit pari-gp") provides several mechanisms of parallelism,
which could be honoured by providing different package variants. 

After discussion with the author, I would suggest to enable the pthread
interface in the standard package (and to not provide an MPI variant unless
someone voices demand). This can be obtained trivially be adding the
configure flag "--mp=pthread". It will transparently parallelise a number
of internal functions according to the number of processor cores, and
should have negligible impact on single-core systems (which hardly exist
nowadays anyway).

What do you think? Are there any objections?

Andreas
