MCE đi kèm với ví dụ khác nhau cho thấy thực tế kịch bản trường hợp sử dụng trên parallelizing một cái gì đó nhỏ như con mèo (thử với -n) để greping cho các mẫu và số lượng từ tập hợp.
barrier_sync.pl
A barrier sync demonstration.
cat.pl Concatenation script, similar to the cat binary.
egrep.pl Egrep script, similar to the egrep binary.
wc.pl Word count script, similar to the wc binary.
findnull.pl
A parallel driven script to report lines containing
null fields. It is many times faster than the binary
egrep command. Try against a large file containing
very long lines.
flow_model.pl
Demonstrates MCE::Flow, MCE::Queue, and MCE->gather.
foreach.pl, forseq.pl, forchunk.pl
These take the same sqrt example from Parallel::Loops
and measures the overhead of the engine. The number
indicates the size of @input which can be submitted
and results displayed in 1 second.
Parallel::Loops: 600 Forking each @input is expensive
MCE foreach....: 34,000 Sends result after each @input
MCE forseq.....: 70,000 Loops through sequence of numbers
MCE forchunk...: 480,000 Chunking reduces overhead
interval.pl
Demonstration of the interval option appearing in MCE 1.5.
matmult/matmult_base.pl, matmult_mce.pl, strassen_mce.pl
Various matrix multiplication demonstrations benchmarking
PDL, PDL + MCE, as well as parallelizing Strassen
divide-and-conquer algorithm. Also included are 2 plain
Perl examples.
scaling_pings.pl
Perform ping test and report back failing IPs to
standard output.
seq_demo.pl
A demonstration of the new sequence option appearing
in MCE 1.3. Run with seq_demo.pl | sort
tbray/wf_mce1.pl, wf_mce2.pl, wf_mce3.pl
An implementation of wide finder utilizing MCE.
As fast as MMAP IO when file resides in OS FS cache.
2x ~ 3x faster when reading directly from disk.
