my $MAX_PROCESSES=10; my $pm = Parallel::ForkManager->new($MAX_PROCESSES); while (1) { my $pid=$pm->start and next; print "$$ LOCK \n"; $pm->finish; } $pm->wait_all_children;
I made this sample piece of code which I basically took from the docs, I only changed to infinite loop but I cannot understand why this would make any different between an infinite loop and iterating through an array for example? Anyway I am fighting this for several hours now trying different versions of my code and cannot find why am I getting "Cannot start another process while you are in the child process" all the time, any hints appreciated
output looks basically like this
Cannot start another process while you are in the child process at .... 16366 LOCK 16367 LOCK 16368 LOCK 16369 LOCK 16370 LOCK 16371 LOCK 16372 LOCK 16373 LOCK 16374 LOCK 16375 LOCK Cannot start another process while you are in the child process at ....

Prior releases of the 6.x line relied on Lexical::Types, which was a major performance pessimisation over the 5.x releases.
6.0.4 relies on a simple source filter instead, which restores performance levels back to expected levels.
More benchmarks added to the test suite validate the dependency changes.

113-bit integer arithmetic
Changes for 0.04
- Allow negative values to be passed to bitwise operators (&, |, ^, ~, >>, <<). These negative values will be converted to their 113-bit 2s-complement value prior to being acted upon by the bitwise operator - thus mimicking perl's treatment of negative 32-bit/64-bit IVs.
- Add divmod() function.
- Add new test file t/bitwise_feature.t

HTTP/2 Dynamic Benchmarks (PHP vs. ModPerl2), 2024 edition.
I ram these about four years ago, and the time differentials were about the same then as now. Monolithic POSIX-threaded server architectures like mp2 + mpm_event will always dominate in low-latency/scalability HTTP/2 benchmarks because they leverage zero-copy in the runtime.
Anyways, sexy terminal graphs with smag to enjoy!

Lessons learned: A) Performance freaks to stop using #rstat 's runif for random generation. The Hoshiro random number generator arxiv.org/abs/1805.01407 is 10x faster. Implementations in #perl 's #PDL, #rstats (dqrng) and #python #numpy are within 20% of each other B) But does it make a difference in applications? To get to the bottom of this, I coded a truncated random variate generator in #rstats and #perl using #pdl (as well as standard u/perl) using the #GSL packages metacpan.org/pod/PDL::GSL::CDF & metacpan.org/pod/Math::GSL for accessing the CDF & quantile functions. In this context, it's the calculation of the #CDF that is the computationally intensive part, not the drawing of the random number itself. C) I should probably blog about these experiments at some point. Note that #pdl (but not base #perl) are rather competitive choices for large array processing with numerical operations. I mostly stay away of #python , but would not surprise me that for compute intensive stuff (where the heavy duty work is done in C/C++), it does not matter (much) which high level language one uses to build data applications preview.redd.it/qn00sx78gbuc1.… preview.redd.it/4by4jbh9gbuc1.… submitted by /u/ReplacementSlight413 |
