RemoveNodeStateAsync() on a node in fabric cluster fails even when the node is in disabled state. -


i have custom auto scale set scaling of nodes in cluster. scale works great. have issues scaling down. problem when want scale down, identify node want remove- after call deactivatenodeasync() method on intent of removing node. wait till deactivation done, check status of node confirm disabled. once disbled call method removenodestateasync() cluster can register node being removed.

but problem - when call removenodestateasync(), getting following exception - says node up. complete exception.

scale containers: scale nodes failed . exception : system.aggregateexception: 1 or more errors occurred. ---> system.aggregateexception: 1 or more errors occurred. ---> system.fabric.fabricexception: node up. ---> system.runtime.interopservices.comexception: exception hresult: 0x80071bc4 @ system.fabric.interop.nativeclient.ifabricclustermanagementclient9.endnodestateremoved(ifabricasyncoperationcontext context) @ system.fabric.interop.utility.<>c__displayclass20_0.b__0(ifabricasyncoperationcontext context) @ system.fabric.interop.asynccalloutadapter2`1.finish(ifabricasyncoperationcontext context, boolean expectedcompletedsynchronously) --- end of inner exception stack trace --- --- end of inner exception stack trace --- @ system.threading.tasks.task.throwifexceptional(boolean includetaskcanceledexceptions) @ system.threading.tasks.task.wait(int32 millisecondstimeout, cancellationtoken cancellationtoken)

what missing ? why saying node after explicitly checking status says node disabled ? how can register cluster node removed. appreciate on this.

i found answer in azure article : https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-cluster-programmatic-scaling

removenodestate needs done after node removed scaleset not before.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
