Message#
The macro definition has multiple migration results in the dimension of free queries function that could not be unified. You may need to modify the code.
Detailed Help#
SYCLomatic was unable to migrate the code correctly. You need to modify the code manually.
For example, this original CUDA* code:
1 namespace cg = cooperative_groups;
2
3 #define TB(b) cg::thread_block b = cg::this_thread_block();
4
5 __global__ void test1() {
6 TB(b);
7 }
8
9 __global__ void test2() {
10 TB(b);
11 }
12
13 void foo() {
14 test1<<<dim3(2, 2, 2), dim3(2, 2, 2)>>>();
15 test2<<<2, 2>>>();
16 }
migrated with options --assume-nd-range-dim=1
and
--use-experimental-features=free-function-queries
,
results in the following migrated SYCL code:
1 /*
2 DPCT1088:0: The macro definition has multiple migration results in the dimension
3 of free queries function that could not be unified. You may need to modify the
4 code.
5 */
6 #define TB(b) \
7 auto b = sycl::ext::oneapi::experimental::this_group< \
8 dpct_placeholder /* Fix the dimension manually */>();
9
10 void test1() {
11 TB(b);
12 }
13
14 void test2() {
15 TB(b);
16 }
17
18 void foo() {
19 sycl::device dev_ct1;
20 sycl::queue q_ct1(dev_ct1,
21 sycl::property_list{sycl::property::queue::in_order()});
22 q_ct1.parallel_for(
23 sycl::nd_range<3>(sycl::range<3>(2, 2, 2) * sycl::range<3>(2, 2, 2),
24 sycl::range<3>(2, 2, 2)),
25 [=](sycl::nd_item<3> item_ct1) {
26 test1();
27 });
28 q_ct1.parallel_for(sycl::nd_range<1>(sycl::range<1>(2) * sycl::range<1>(2),
29 sycl::range<1>(2)),
30 [=](sycl::nd_item<1> item_ct1) {
31 test2();
32 });
33 }
which is manually adjusted to:
1 #define TB(b, d) \
2 auto b = sycl::ext::oneapi::experimental::this_group<d>();
3
4 void test1() {
5 TB(b, 3);
6 }
7
8 void test2() {
9 TB(b, 1);
10 }
11
12 void foo() {
13 sycl::device dev_ct1;
14 sycl::queue q_ct1(dev_ct1,
15 sycl::property_list{sycl::property::queue::in_order()});
16 q_ct1.parallel_for(
17 sycl::nd_range<3>(sycl::range<3>(2, 2, 2) * sycl::range<3>(2, 2, 2),
18 sycl::range<3>(2, 2, 2)),
19 [=](sycl::nd_item<3> item_ct1) {
20 test1();
21 });
22 q_ct1.parallel_for(sycl::nd_range<1>(sycl::range<1>(2) * sycl::range<1>(2),
23 sycl::range<1>(2)),
24 [=](sycl::nd_item<1> item_ct1) {
25 test2();
26 });
27 }
Suggestions to Fix#
Rewrite the code manually.
