Dear List,
this is a continuation of previous messages.
I am trying to do a sparse triangular solve using a CSR matrix.
the point is that some rows can be computed directly, while some others
need to wait
for the specific example i post
lines 0 4 5 can be computed independelty
while 1 must wait for 2
2 must wait for 1
3 must wait for 2
in a more general case a line may have to wait for multiple other lines to
be executed.
essentially what i am trying to do is to say that a given line must wait
for its dependencies before being processed.
I have been trying to achieve this all day without success.
My latest attempt is with a lambda, but the captured values at the moment
of running (in particular i) are not the ones when i launch it, which
essentially means that my usage must be wrong.
(and it definitely is, as in the version i post the dependencies on the
shared futures is not there)
essentially the function to futurize is the one on line 65 of
https://gist.github.com/RiccardoRossi/4adbdb29e1c94da8fefc4afdcf6b1e37
my guess is that knowning how to actually do it, the change to my code for
having it to run should be minimal ... but i am simply not able to do it
succesfully
any help would be great
cheers
Riccardo
