- PNG, FBX, JSON More common with indie games ▶ Maximal extreme Large process - requires entire server farm Creates lots of data - even more to process Outputs optimised binary files - loaded quickly into regions - process as separate tasks Changing one region should not affect others Some tasks will take longer - more data to process in region Hope all jobs are similar in size If not then small jobs requires having quick access to static world data Many regions of the world - many tasks for each region Need to prevent everyone from duplicating work - and code ▶ Traditionally use one of tree structures

toolchains allow you to disable all optimizations for a region of code, which is one way to avoid this problem.  Disabling all optimizations for a region of code can be overkill.  You’ll probably also lose Non-Volatile Operations  volatiledisables optimizations for a specific object rather than for a region of code.  The compiler can still optimize accesses to non-volatile objects in the surrounding

the host and device(s) in a span of bytes Pointers within that region of memory can freely point to any other address in the region Easier to port existing C/C++ code to SYCLMemory is allocated manuallySome platforms will support variants of USM where memory allocations share the same memory region between the host and device(s) No explicit routines are required to move the dataExplicit USM
