Segmentation fault of sample code in readme.md on mac #34

Closed ghost closed 10 years ago

ghost commented 10 years ago

When I try to run the sample code in readme.md on my mac, it gives segmentation fault, which is for the function clblasSgemm.

kknox commented 10 years ago

Hi @yjuboiler I have a ~2011 macbook pro (with a discrete Radeon HD 6750M), and Mavericks installed. I compiled the library from source, and then linked the example code to the dylib. It runs to completion for me.

We may need more information about your setup. Do you have a GPU device?

kknox commented 10 years ago

I'm going to close this issue soon due to inactivity.

Hi @kknox I have the same issue here. clblasSgemm gives segmentation fault on 2013 mac pro with Yosemite + Intel Iris. I modified the code in the readme and checked that it actually found GPU device info. Could you help me figure out this issue?

This is what I printed out in the sample code

char buffer[30];
cl_bool param;
clGetDeviceInfo(device, CL_DEVICE_NAME, sizeof(buffer), buffer, NULL);
printf("device: %s\n", buffer);
clGetDeviceInfo(device, CL_DEVICE_VERSION, sizeof(buffer), buffer, NULL);
printf("device_version: %s\n", buffer);
clGetDeviceInfo(device, CL_DEVICE_COMPILER_AVAILABLE, sizeof(param), &param, NULL);
printf("device_compiler_available: %u\n", param);
clGetDeviceInfo(device, CL_DRIVER_VERSION, sizeof(buffer), buffer, NULL);
printf("driver_version: %s\n", buffer);

gives

device: Iris
device_version: OpenCL 1.2 
device_compiler_available: 1
driver_version: 1.2(Sep 25 2014 22:25:51)

and clblasSetup() does not complain anything. I attached cmake log since I am not sure if I did correctly.. (I only built runtime library though)
