我有一个相当复杂的mql5 for循环代码集,需要通过opencl运行。这意味着我需要有一些调用其他函数的内核函数。因此,我尝试了这个简单的代码,当我通过它调用另一个函数时,它无法创建程序(错误5105)。为什么?
const string _cl_source=
" \r\n"
" \r\n"
"__kernel void Tester() \r\n"
"{ \r\n"
" \r\n"
" float _margin = 10f; \r\n"
" float _balance = 10f; \r\n"
" float _equity = 10f; \r\n"
" float _openprice = 10f; \r\n"
" float _closeprice = 10f; \r\n"
" float _position = 10f; \r\n"
" \r\n"
/*fails on adding this line*/" CouponReset(_margin,_balance,_equity,_openprice,_closeprice,_position);\r\n"
" \r\n"
"} \r\n"
" \r\n"
" \r\n"
"__kernel void CouponReset(float margin, \r\n"
" float balance, \r\n"
" float equity, \r\n"
" float openprice, \r\n"
" float closeprice, \r\n"
" float position) \r\n"
"{ \r\n"
" position = 0f; \r\n"
" openprice = 0f; \r\n"
" closeprice = 0f; \r\n"
" balance = equity; \r\n"
" margin = balance; \r\n"
" \r\n"
"} \r\n"
" \r\n";
最佳答案
编辑:实际上,我对此进行了审查,并且有可能从另一个内核调用一个内核。但是,您不应该这样做,因为这可能会导致您遇到麻烦(特别是如果使用__local
内存)。
您应用中的关键问题只是0.0f
浮点数。
您也可以做一个单独的函数,两个内核都调用。其中之一只是对该函数的包装。
void _CouponReset(float margin,
float balance,
float equity,
float openprice,
float closeprice,
float position)
{
position = 0.0f;
openprice = 0.0f;
closeprice = 0.0f;
balance = equity;
margin = balance;
}
__kernel void Tester()
{
float _margin = 10.0f;
float _balance = 10.0f;
float _equity = 10.0f;
float _openprice = 10.0f;
float _closeprice = 10.0f;
float _position = 10.0f;
_CouponReset(_margin,_balance,_equity,_openprice,_closeprice,_position);
}
__kernel void CouponReset(float margin,
float balance,
float equity,
float openprice,
float closeprice,
float position)
{
_CouponReset(margin, balance, equity, openprice, closeprice, position);
}
