Currently, an issue has been observed in the Aurora compiler, where errors occur during the compilation of certain programs. The details are as follows:
In versions 5.2.0 and later of the Aurora compiler, the optimization feature for common subexpression elimination after vectorization (-fcse-after-vectorization) is enabled by default. (In versions prior to 5.2.0, this optimization was disabled by default.)
However, there is a problem with the compiler’s processing during the application of this optimization after vectorization, which has led to compiler errors.
At this time, the release of a corrected version of the Aurora compiler and the timing for its application to the SQUID system are both undetermined.
As a temporary workaround, the following is recommended:
Temporary workaround:
Add the option -fno-cse-after-vectorization during compilation to suppress the common subexpression elimination optimization after vectorization, which will prevent the error.
We apologize for the inconvenience and greatly appreciate your understanding and cooperation.
