6678 main函数 通过IPC_start()后

在main函数通过DNUM函数获取核数打印时候没有打印出核0，在经过Ipc_start()同步后，通过status检测同步正常，但是MutiProc_self()获取不到核0.

Nancy Wang：

您是参考的哪个例程？麻烦贴出来相关的代码以及配置文件。

尝试一下在Multiproc_self前调用MultiProc_setLocalId。

你好我参考vlfft历程，有个setMyId函数，这个函数已经显示调用MultiProc_setLocalId(procId)

您的问题解决了吗？可以将您的project传上来吗？我转给相关的工程师看一下。
