How to get original location of script used for SLURM job?

由 a 夏天 提交于 2020-01-04 13:35:10
问题 I'm starting the SLURM job with script and script must work depending on it's location which is obtained inside of script itself with SCRIPT_LOCATION=$(realpath $0) . But SLURM copies script to slurmd folder and starts job from there and it screws up further actions. Are there any option to get location of script used for slurm job before it has been moved/copied? Script is located in network shared folder /storage/software_folder/software_name/scripts/this_script.sh and it must to: get it's

问题 So, I am trying to simplify the use of my generic classes and came across the following idea: The following struct is given: template <size_t size> struct Vector { std::array<float, size> data; float& x = data[0]; float& y = data[1]; // Declare y only if size is > 0 float& z = data[2]; // Declare z only if size is > 1 float& w = data[3]; // Declare w only if size is > 2 }; Obviously, if I try to run the program like this, the array will throw an out of range exception. Now is there a way to

问题 #include<stdio.h> int main() { int a=20,b=30; a=a+b; b=a-b; a=a-b; return 0; } Can I use this program to swap both positive and negative values. 回答1: The algorithm for swapping variables without a temporary holder uses the bitwise XOR operation, not subtraction. So, using variables named a and b , we'd have: a=a^b; b=a^b; a=a^b; EDIT: Your code does work for the few cases I tested it with using some integral values for a and b , but XOR is the conventional way of doing it.

问题 I have three textboxes ct1,ct2,ct3. I have to use a for loop 1 to 3 and check whether the textboxes are empty. So, inside the for loop, how do I represent it? For example, for(i=0;i<=3;i++) { if(ct+i.getText()) // I know I'm wrong { } } 回答1: I have three textboxes ct1,ct2,ct3. There's your problem to start with. Instead of using three separate variables, create an array or collection: TextBox[] textBoxes = new TextBox[3]; // Populate the array... Or: List<TextBox> textBoxes = new ArrayList

问题 I'm trying to patch a class with ASM. I need to add some logic in a function. This logic needs a new local variable.
