# ParallelTable kernels die - maybe Mathlink timeout?

I am new to parallel computing in Mathematica. I am using

LaunchKernels[16]
ParallelTable[]


to parallelize calculations. The ParallelTable consists of approx 10000 elements that are calculated using a routine which in certain cases can take a couple of minutes to finish. After starting the notebook I get after a while a bunch of errors:

LinkObject::linkd: Unable to communicate with closed link LinkObject[/path/math -subkernel -noinit -mathlink, 102, 16].

ParallelDeveloperQueueRun::req: Requeueing evaluations {11} assigned to KernelObject[16, local, <defunct>].

• I had the same errors here using ParallelMap. You can try the option Method -> "FinestGrained" to minimize the time each kernel is busy without giving any feedback. – Karsten 7. Dec 31 '14 at 15:17
