Controlling batch_mode memory allocation for quantum chemistry calculations #396

Closed tanvipg closed 5 years ago

tanvipg commented 5 years ago

What is the expected enhancement?

For bigger molecules batch_mode = true causes memory crash. Proposed enhancement is to control the number of circuits created. @pistoia @chunfuchen @liupibm

liupibm commented 5 years ago

proposed a fix. waiting for @tanvipg to check how the fix works.

tanvipg commented 5 years ago

Checked the fix, memory crash does not happen anymore. Performance of the functionality needs to be tested with the new fix. @liupibm working on it.

woodsp-ibm commented 5 years ago

The memory issue was fixed and performance has been investigated and reported.
