How to declare dynamic properties with Google Closure Compiler?
Date : March 29 2020, 07:55 AM
Any of those help This falls under the Restrictions for ADVANCED_OPTIMIZATIONS of the documentation. You must consistently refer to properties using either the dotted notation or quoted syntax. When you mix access, the compiler may rename the dotted access, but will not touch the quoted syntax and thus generate incorrect code.

How to declare global variable for google closure compiler?
Date : March 29 2020, 07:55 AM
may help you . As Rohan points out in the comments, the Closure compiler thinks of window.myGlobal and myGlobal as different things, even though you and I know they are actually the same. If you need to define it inside a function, you could do something like var myGlobal;
(function() { myGlobal = 42; })();
console.log(myGlobal);
window.myGlobal = null;
(function() { window.myGlobal = 42; })();
console.log(window.myGlobal);

Can I use printf(or something) in OpenACC with PGI compiler?
Date : March 29 2020, 07:55 AM
This might help you Posting the answer from the above comments for completeness.
Building with -g and setting LD_LIBRARY_PATH to point to the toolkit directory /linux86-64/lib resolved this issue.

How to perform manual deep copy of 2D dynamic array of struct in C using OpenACC
Date : March 29 2020, 07:55 AM
this one helps. Close. The only thing I'd do different is to not create "domain.bucket" and update the bucket's count so the device has this information. Also, since updates/copies are shallow, be sure to only update the list array or scalars in the structs. Otherwise you may overwrite device/host pointers. Here's an example. While I'm using Linux, other than the executable name, the code should the same. % cat test.c
#include <stdio.h>
#include <stdlib.h>
typedef struct{
int *list; // it is list of particles in a given bucket
int count; // it is the total number of particles in the bucket
} structBucket;
typedef struct{
structBucket **bucket;
int numberOfBuckets[2]; // number of buckets in x- and y- dimensions
} structDomain;
#define XDIM 64
#define YDIM 64
int main() {
structDomain domain;
int iX,iY, capacity;
// Allocate memory for **bucket
domain.numberOfBuckets[XDIM] = 10; domain.numberOfBuckets[YDIM] = 5;
domain.bucket = (structBucket**)malloc( sizeof(structBucket*) * domain.numberOfBuckets[XDIM] );
for (iX=0 ; iX < domain.numberOfBuckets[XDIM] ; iX++)
domain.bucket[iX] = (structBucket*)malloc( sizeof(structBucket) * domain.numberOfBuckets[YDIM]);
// Calculate domain.bucket[iX][iY].count here using some logic
for (iX = 0; iX < domain.numberOfBuckets[XDIM]; iX++)
{
for (iY = 0; iY < domain.numberOfBuckets[YDIM]; iY++)
{
domain.bucket[iX][iY].count = iX*domain.numberOfBuckets[YDIM]+iY;
}}
#pragma acc enter data copyin(domain)
#pragma acc enter data create(domain.bucket[:domain.numberOfBuckets[XDIM]][:domain.numberOfBuckets[YDIM]])
// Allocate memory for *list
for (iX = 0; iX < domain.numberOfBuckets[XDIM]; iX++)
{
for (iY = 0; iY < domain.numberOfBuckets[YDIM]; iY++)
{
capacity = domain.bucket[iX][iY].count;
#pragma acc update device(domain.bucket[iX][iY].count)
if (capacity > 0)
{
domain.bucket[iX][iY].list = (int *)malloc(sizeof(int) * capacity);
#pragma acc enter data create(domain.bucket[iX][iY].list[:capacity])
}
}
}
#pragma acc parallel loop gang collapse(2) present(domain)
for (iX = 0; iX < domain.numberOfBuckets[XDIM]; iX++)
{
for (iY = 0; iY < domain.numberOfBuckets[YDIM]; iY++)
{
capacity = domain.bucket[iX][iY].count;
if (capacity > 0) {
#pragma acc loop vector
for (int i = 0; i < capacity; ++i) {
domain.bucket[iX][iY].list[i] = i;
}
}
}}
for (iX = 0; iX < 5; iX++)
{
for (iY = 0; iY < 5; iY++)
{
capacity = domain.bucket[iX][iY].count;
if (capacity > 0) {
#pragma acc update host(domain.bucket[iX][iY].list[:capacity])
printf("iX=%d iY=%d Cnt=%d\n\t",iX,iY,capacity);
for (int i = 0; i < capacity; ++i) {
printf("%d ",domain.bucket[iX][iY].list[i]);
}
printf("\n");
}
}}
exit(0);
}
