One minor point, with the extra project.clj settings, as the repl starts up, I see
Java HotSpot(TM) 64-Bit Server VM warning: Failed to reserve shared memory (errno = 22).
from clojurecl.
Can you please run info function on the platform and on that device and verify that they support OpenCL version 1.2? clReleaseDevice was introduced in OpenCL 1.2, so the crash may be caused by calling the non-existing function. Also, please try with-release on some other type of object - if it works, I am pretty sure the problem is a pre-1.2 platform driver.
Please post the outputs of those two info calls. Obviously, since I do not have nvidia platform available to me, I can not try it myself, but I'll try to identify the problem and at least find whether it is in ClojureCL or not, so we can find a solution.
from clojurecl.
(info (first (platforms))) gave me
#uncomplicate.clojurecl.info.PlatformInfo{:profile "FULL_PROFILE", :version "OpenCL 1.1 CUDA 7.0.41", :name "NVIDIA CUDA", :vendor "NVIDIA Corporation", :extensions #{"cl_khr_gl_sharing" "cl_nv_copy_opts" "cl_khr_icd" "cl_nv_pragma_unroll" "cl_khr_byte_addressable_store" "cl_nv_device_attribute_query" "cl_nv_compiler_options"}, :icd-suffix-khr "NV"}
So I'm not even on opencl 1.2.
Devices give a larger result confirming the same (pasted below).
I isolated the jvm crash to just with-release
on dev
So this works:
(def dev (first (devices (first (platforms)))))
(let [work-sizes (work-size [1])
host-msg (direct-buffer 16)
program-source
"__kernel void hello_kernel(__global char16 *msg) {\n *msg = (char16)('H', 'e', 'l', 'l', 'o', ' ',
'k', 'e', 'r', 'n', 'e', 'l', '!', '!', '!', '\\0');\n}\n"
]
(with-release
[
;;dev (first (devices (first (platforms))))
ctx (context [dev])
cqueue (command-queue ctx dev)
cl-msg (cl-buffer ctx 16 :write-only)
prog (build-program! (program-with-source ctx [program-source]))
hello-kernel (kernel prog "hello_kernel")
]
(set-args! hello-kernel cl-msg)
(enq-nd! cqueue hello-kernel work-sizes)
(enq-read! cqueue cl-msg host-msg)
(apply str (map char
(wrap-byte-seq int8 (byte-seq host-msg))))))
-->> "Hello kernel!!!"
(info dev)

Thank you for this library, it will make openCL so much more approachable.
from clojurecl.
OK, so it works as expected. I'll close the issue. The point for posterity is that, if you use an older version of the OpenCL platform, you should use only the functionality supported by that particular version of the standard. Follow the links from clojurecl API to khronos's website, but change the version in the link to the one you use.
from clojurecl.
For easy access, the link to the api docs is here: http://clojurecl.uncomplicate.org/codox/uncomplicate.clojurecl.core.html
Each function doc also links to the khronos page.
Thanks to blueberry for clarifying this for me!
