Member Enumeration Documentation

◆ StoragePolicy

enum madness::MacroTaskInfo::StoragePolicy

Enumerator

StoreFunction

store a madness function in the cloud – can have a large memory impact

StorePointerToFunction

store the pointer to the function in the cloud, the actual function lives in the universe and its coefficients can be copied to the subworlds (e.g. by macrotaskq) when needed. The task itself is responsible for handling data movement

StoreFunctionViaPointer

coefficients to the subworlds when the task is started. This is the default policy.

store a pointer to the function in the cloud, but macrotaskq will move the

return some preset policies

"default": StoreFunctionViaPointer, cloud rank-replicated, initial functions node-replicated
"small_memory": StoreFunctionViaPointer, cloud rank-replicated, initial functions distributed
"large_memory": StoreFunction, cloud rank-replicated, initial functions distributed the user can also set the policies manually note: the policies are checked for consistency when the MacroTaskQ is created
