Re: X2GO client connection failure: Socket Disconnected
Hello, I encounter a similar issue. Here are the steps: On login-2 node: devcloud_login Choose 1) Arria 10 PAC Compilation and Programming - RTL AFU, OpenCL and 1) 1.2.1 In a new mobaxterm: ssh -L 4002:s005-n003:22 colfax-intel Start an X2GO session, and I got such an error: Any idea? Thanks! HongboRe: OpenCL to OneAPI Dramatic change in Frequency and Performance
I compared the two files: kdiff3 a.cl gemm.generated_oneapi_header.h One suspicious place is that OpenCL code uses vload16, but OneAPI does not: OpenCL (a.cl, line 116): float16 _29 = vload16(0, (__address_space__A_serializer float*)_A_serializer + _28); OneAPI (gemm.generated_oneapi_header.h, 2755): _158 = { _A_serializer[_157+0], _A_serializer[_157+1], _A_serializer[_157+2], _A_serializer[_157+3], _A_serializer[_157+4], _A_serializer[_157+5], _A_serializer[_157+6], _A_serializer[_157+7], _A_serializer[_157+8], _A_serializer[_157+9], _A_serializer[_157+10], _A_serializer[_157+11], _A_serializer[_157+12], _A_serializer[_157+13], _A_serializer[_157+14], _A_serializer[_157+15] }; Another suspicious place is the use of fpga_reg with float16: OpenCL (a.cl 193): float16 _61 = __fpga_reg(__fpga_reg(_60)); OneAPI (gemm.generated_oneapi_header.h, 2852): float16 _190 = (float16){ sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[0])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[1])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[2])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[3])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[4])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[5])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[6])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[7])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[8])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[9])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[10])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[11])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[12])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[13])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[14])), sycl::ext::intel::fpga_reg( sycl::ext::intel::fpga_reg(_189[15])) }; Anyone knows how to (1) use vload16 in OneAPI? (2) use fpga_reg for float16 type? Thanks!
