-  - E.g.: CU_MASK=3-8,16 would request Transfer be executed only CUs 3,4,5,6,7,8,16
-  - NOTE: This is somewhat experimental and may not work on all hardware

+* Adding the `CU_MASK` environment variable, which allows you to select the CUs to run on
+* `CU_MASK` is specified in CU indices (0-#CUs-1), where ' - ' can be used to denote ranges of values
+  (e.g., `CU_MASK`=3-8,16 requests that transfer be run only on CUs 3,4,5,6,7,8,16)

-    - Setting NUM_CPU_DEVICES=0 can be used to only benchmark GPU devices (like "g2g")
-    - New environment variable USE_REMOTE_READ replaces "_rr" presets
-  - New environment variable USE_GPU_DMA=1 replaces USE_HIP_CALL=1 for benchmarking with GPU-DMA Executor
