| I took an example from Data::Dump::Tree (DDT)and started playing with Promises, the | |
| goal was simply educative, I am following "Parallelism, Concurrency, | |
| and Asynchrony in Perl 6" document to try the different mechanisms. The final goal | |
| being the parallelization of DDT as it is too sluggish and also in preparation of | |
| Asciio 2.0. | |
| <jnthn> | |
| 1 will probably because the thread pool over-subscribes the CPU. Second is 'cus you exhausted the thread pool (16 is the number of threads it has by default). Third one may be a data race that's worth reporting. | |
| First two are already known about; the latter being addressed by making await non-blocking (available in 6.d.PREVIEW) | |
| The first just needs the time spent making the pool size itself more sensibly in respones to the kind of workload | |
| <nadim> I don't see how the first case differs from the first run and the last run. I await all the threads in each iteration so the thread pool should be full [no thread running] at each itertation [start] | |
| how does await non blocking fix second problem? I'd like to know I have reached the pool limit when I run start not later when I use await. or I am not understanding it right? I'd rather have an exception thrown directly when using start. or that things get aueued without me thinking about the thread pool. | |
| <jnthn> Everyone would love not to have to think. | |
| <nadim> An exception makes people think, like it or not | |
| Problem 1 | |
| ========= | |
| for ^50 | |
| { | |
| $dump_start = now ; | |
| my $d1 = start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| my $d2 = start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| my $d3 = start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| my $d4 = start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| my $d5 = start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| my $d6 = start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| my $d7 = start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| my $d8 = start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| await $d1, $d2, $d3, $d4, $d5, $d6, $d7, $d8 ; | |
| say "dump time: {now - $dump_start} s" ; | |
| } | |
| The problem is that it first iterates quickly and then slows down considerably | |
| dump time: 0.24248294 s # first iteration | |
| dump time: 0.2493730 s | |
| dump time: 0.2249258 s | |
| dump time: 0.25128736 s | |
| dump time: 0.24334974 s | |
| dump time: 0.2577809 s | |
| ... | |
| dump time: 0.4216805 s | |
| dump time: 0.404167881 s | |
| dump time: 0.40570028 s | |
| dump time: 0.41778251 s | |
| dump time: 0.4126616 s # last iteration | |
| I ran it with 500 iteration, around iteration 150 the time seems to stabilize just below 0.5s. | |
| At iteration 500 it is half the time under 0.5s and half the time very slightly higher | |
| with peaks around 0.7 s | |
| execution slowing down | |
| ---------------------- | |
| I changed the code to this loop and that call to ddt to show the promises, wrongly calling promises | |
| threads in my example. | |
| for ^15 | |
| { | |
| @threads.push: start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| } | |
| ddt @threads ; | |
| that worked fine and fast. I changed the code to | |
| for ^16 # change from ^15 to ^16 | |
| { | |
| @threads.push: start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| } | |
| ddt @threads ; | |
| that doesn't work at all. The "ddt @threads" does not get executed, nothing get's schedules, no CPU is used. It's dead Jim. | |
| random errors | |
| ------------- | |
| I changed the code to | |
| for ^15 # change back to ^15 | |
| { | |
| @threads.push: start $d.ddt: :get, { :$config, :$regex, :$match }, :title<config parsing>, :elements_filters[&sorter] ; | |
| } | |
| ddt @threads, :flat{1, 5} ; #changed the option to ddt | |
| The option to ddt makes the rendering much slower, slow enough to that some promises get scheduled before the | |
| ddt call returns. | |
| I ran it mucltiple times on the command line, sometimes it works, like the example below: | |
