Unless the BOINC code has changed since I checked it out via git-v2 a
couple weeks ago, I have to say it is a qualified yes, but you have to
create your own custom sched _customize code to do it.
The stock sched_customize does not take into account having CAL and not
OpenCL or the reverse. You can change the flops scale a little to choose
one over the other if both are present, but that logic doesn't handle it
100%. Nor does it distinguish between CAL and Brook support or the IL
changes to the HD 7xxx GPUs that cause it to no longer run Brook+ apps
correctly. But, you can do it if the client is running a recent BOINC
version.
The coproc.attribs.target property contains the AMD GPU family. See the
cal_boinc.h for an abbreviated list. The list I use is as follows:
CAL_TARGET_600, /**< R600 GPU ISA */
CAL_TARGET_610, /**< RV610 GPU ISA */
CAL_TARGET_630, /**< RV630 GPU ISA */
CAL_TARGET_670, /**< RV670 GPU ISA */
CAL_TARGET_7XX, /**< R700 class GPU ISA */
CAL_TARGET_770, /**< RV770 GPU ISA */
CAL_TARGET_710, /**< RV710 GPU ISA */
CAL_TARGET_730, /**< RV730 GPU ISA */
CAL_TARGET_CYPRESS, /**< RV870 GPU ISA */
CAL_TARGET_JUNIPER, /**< RV830 GPU ISA */
CAL_TARGET_REDWOOD, /**< REDWOOD GPU ISA */
CAL_TARGET_CEDAR, /**< CEDAR GPU ISA */
CAL_TARGET_RESERVED0,
CAL_TARGET_RESERVED1,
CAL_TARGET_WRESTLER, /**< WRESTLER GPU ISA */
CAL_TARGET_CAYMAN, /**< CAYMAN GPU ISA */
CAL_TARGET_RESERVED2,
CAL_TARGET_BARTS, /**< BARTS GPU ISA */
CAL_TARGET_TURKS, /**< TURKS GPU ISA */
CAL_TARGET_BROKEN1,
CAL_TARGET_BROKEN2,
CAL_TARGET_BROKEN3,
CAL_TARGET_BROKEN4,
CAL_TARGET_BROKEN5,
CAL_TARGET_BROKEN6,
CAL_TARGET_BROKEN7,
CAL_TARGET_BROKEN8,
CAL_TARGET_BROKEN9
Using the target, anything 20 (BROKEN1 or greater) means HD7xxx or newer
which distinguishes the GPUs won't run Brook+ correctly. Combined with the
have_cal and have_opencl properties, you should be able to do the checks
you want. For example:
//To send OpenCL apps to HD7xxx or later
if ((c.attribs.target > 19) && (c.have_opencl))
//To send CAL/Brook+ apps to HD6xxx and earlier
if ((c.attribs.target < 20) && (c.have_cal))
//To send OpenCL apps to any AMD GPU that supports it
if ((c.attribs.target > 8) && (c.have_opencl))
//To send CAL apps to any AMD GPU that can't run OpenCL
if ((c.attribs.target < 9) && (c.have_cal))
Note: c.attribs.target may be 0 if it is an older client. It was added
prior to BOINC 7.x.x but after BOINC 6.6.0.
If anyone has an easier or better way, I'd like to know about it.
