FYI, these interfaces may change in the near future. Currently GOMP_OFFLOAD_get_table returns a joint table for all images, offloaded to a device. But this doesn't work properly with offloading from dlopened libs. Do you plan to support such cases for PTX? Perhaps it's worth to replace them with a function like GOMP_OFFLOAD_load_image, which will offload one image, and return a target table for this image. In this case there is no need to pass host_table to the plugin, and return a joint table, since libgomp will join host and target tables itself. Another question is what to do with multiple devices of same type. Can they have different images? There are 2 options: 1. GOMP_OFFLOAD_load_image will offload one image to one device and receive a table from it. or 2. GOMP_OFFLOAD_register_image will register one image in the plugin for all devices of same type, and GOMP_OFFLOAD_get_table will return a table for one image and for one device. Multiple MICs can't have different images, but for the generality we can use option #1. -- Ilya
