Thanks Jesse. I submitted a request and Amazon increased my maximum vCPUs to 164. Now I can run jobs in the Wolfram batch stack using 96 vCPUs. But this has raised yet another question--can I use all of the 164 vCPUs Amazon has allotted to me? I tried rebuilding the batch stack setting the maximum number of vCPUs in the Wolfram template to 164. Unfortunately, I found that a test job using 128 vCPUs would not move out of a Runnable status even after an hour, so I killed the job. Is it possible for me to use more than 96 vCPUs, or does something in Wolfram's setup prevent the use of more than 96 vCPUs in any event? If it is possible to use more than 96 vCPUs, how do I setup the batch stack to allow it? Thanks!

This is my first try to run a code on AWS.
I have a job that executes locally is the following code:

deviceS=Flatten@ParallelTable[dection@deviceS[[i]], {i, 1, Length@deviceS}];

I rewrite it in the following way, hoping to execute it on AWS:

deviceS=RemoteBatchMapSubmit[env, 
  Flatten@ParallelTable[dection@deviceS[[i]], {i, 1,  Length@deviceS}], 
  RemoteProviderSettings -> <|"VCPUCount" -> 8, 
    "Memory" -> Quantity[32, "Gibibytes"]|>, 
  LicensingSettings -> <|Method -> "OnDemand"|>];

No response for a long time. Can you help me see what is wrong? Besides, my original data (deviceS) is a huge file (I save it as mx file). Should it be better to upload to AWS first?
