Cancel Bioinformatics Pipeline Blocks Running in Parallel
Import the pipeline and block objects needed for the example.
import bioinfo.pipeline.Pipeline import bioinfo.pipeline.block.*
Create a pipeline.
P = Pipeline;
Add some pause blocks for illustration purposes. Each block pauses for 1 and 10 seconds, respectively.
PB1 = UserFunction(@() pause(1)); PB2 = UserFunction(@() pause(10)); addBlock(P,[PB1,PB2]);
Run the pipeline in parallel.
run(P,UseParallel=true);
Starting parallel pool (parpool) using the 'Processes' profile ... Connected to parallel pool with 4 workers.
Let the pipeline run for a few seconds in parallel. Then cancel the pipeline while it is still running.
cancel(P);
Check the process table that contains the run status of each block. Set Expanded
to true to expand the process table variable values which are in cell arrays.
t = processTable(P,Expanded=true)
t=2×5 table
Block Status RunStart RunEnd RunErrors
________________ ______ ____________________ ____________________ ________________
"UserFunction_1" Error 26-Jul-2023 08:51:44 26-Jul-2023 08:51:44 {1×1 MException}
"UserFunction_2" Error 26-Jul-2023 08:51:44 26-Jul-2023 08:51:44 {1×1 MException}
You can extract more information from the process table. For example, check the run status of the first block.
PB1Info = t(1,:); PB1Info.Status
ans = RunStatus enumeration Error
Check any error message associated with the block.
PB1Info.RunErrors{:}
ans = MException with properties: identifier: 'parallel:fevalqueue:ExecutionCancelled' message: 'Execution of the future was cancelled.' cause: {} stack: [0×1 struct] Correction: []
