Difference between revisions of "Rupture Variation Generator v5.4.2 code changes"

Latest revision as of 20:01, 10 October 2019

This page documents the code changes required to turn the stand-alone version, genslip-v5.4.2, into an API callable by the CyberShake post-processing.

In this document, $ROOT_DIR is taken to be the <CyberShake home>/software/RuptureCodes/RupGen-api-5.4.2 directory. GenRandV5.0 is the code as received from Rob Graves.

Installing files

Create src, include, lib, and bin directories inside $ROOT_DIR .
Inside src, create GenRandV5.0.
Copy rupgen_api.c from a previous API version into src.
Copy rupgen_defs.h from a previous API version into src.
Create a symlink to rupgen_defs.h in src/GenRand5.0.
Copy rupgen_api.h from a previous API version into src.
Create a symlink to rupgen_api.h in src/GenRand5.0.
Confusingly, there are two files named structure.h. One is in StandRupFormat and contains the structures needed for an SRF. The other is in GenRandV5.0 and contains the definition for complex, along with a few other supporting structures.
1. Copy the StandRupFormat/structure.h into src/srf_structure.h .
2. Copy the GenRandV5.0/structure.h into src/structure.h .
3. Create a symlink to both files in src/GenRandV5.0.
There are also two files named defs.h.
1. Copy GenRandV5.0/StandRupFormat/defs.h into src/GenRandV5.0/srf_defs.h .
2. Copy GenRandV5.0/defs.h into src/GenRandV5.0/defs.h .
From the code provided by Rob, copy the following files into src/GenRandV5.0. Some of them are only lightly used, but it's easier to copy in the entire file rather than only taking the needed functions:
- defs.h
- function.h
- include.h
- fourg.f
- genslip-v5.4.2.c
- gslip_srf_subs.c
- iofunc.c
- misc.c
- ruptime.c
- slip.c
- sliprate_subs.c
- srf_subs.c (from StandRupFormat)
- wafront2d-rwg.f
- makefile
Copy Makefile from a previous API version into src.

Editing files

In $ROOT_DIR/src

structure.h

At the top of the file, change '#include "StandRupFormat/structure.h"' to '#include srf_structure.h'
Above that line, add:
```
#ifndef STRUCT_H
#define STRUCT_H
```
At the end of the file, add:
```
#endif
```

srf_structure.h

At the top of the file, add:

#ifndef SRF_STRUCT_H
#define SRF_STRUCT_H

At the end of the file, add:
```
#endif
```

Makefile

Edit the GETPAR values to point to the getpar install.
Edit GENSLIP to have the same name as the GenRandV5.0 directory.
Edit the library creation line (under the librupgen.a target, starts with $(AR)) to point to the correct version of genslip.

In GenRandV5.0

defs.h

At the top of the file, add:

#ifndef DEFS_H
#define DEFS_H

#include "srf_defs.h"

Delete DEFAULT_SHAL_VRUP_FRAC, as it is not used anymore.
At the end of the file, add:
```
#endif
```

srf_defs.h

At the top of the file, add:
```
#ifndef SRF_DEFS_H
#define SRF_DEFS_H
```
Delete DEFAULT_SHAL_VRUP_FRAC, as it is not used anymore.
Delete the lines corresponding to RDONLY_FLAGS, RDWR_FLAGS, CROPTR_FLAGS, and the _FILE_OFFSET_BITS if statement, as this already exists in defs.h.
At the end of the file, add:
```
#endif
```

include.h

At the top of the file, add:

#ifndef RUPGEN_INCLUDE_H
#define RUPGEN_INCLUDE_H

At the end of the file, add:

#include <string.h>
#include "fftw3.h"

#include "rupgen_api.h"
#include "rupgen_defs.h"

#ifdef _USE_MEMCACHED
#include <libmemcached/memcached.h>
#endif

#endif

function.h

At the top of the file, add:

#ifndef RUPGEN_FUNC_H
#define RUPGEN_FUNC_H

#include "structure.h"

Change the entry for read_ruppars to _read_ruppars, like:

struct pointsource *_read_ruppars(char *,struct pointsource *,float *,int *,int *,float *,float *,float *,float *,float *,float *,float *);

Add an entry for get_rupt:

void get_rupt(struct velmodel* vm, float* h, float* srcd, float* recd, float* srcr, float* recr, double* p, double* rad, float* tt);

Add an entry for zapit:
```
void zapit(float* s,int n);
```

At the end of the file, add:

void write_srf1(struct standrupformat *srf,char *file,int bflag);
void write_srf2(struct standrupformat *srf,char *file,int bflag);

#ifdef _USE_MEMCACHED
int mc_genslip(int ac,char **av, rg_stats_t *stats, struct standrupformat* srf, int state, char* mc_server);
struct pointsource* _mc_read_ruppars(char *file,struct pointsource *psrc,float *mag,int *nx,int *ny,float *dx,float *dy,float *dtop,float *stk,float *dip,float *elon,float *elat, char* mc_server);
#else
int genslip(int ac,char **av, rg_stats_t *stats, struct standrupformat* srf, int state);
#endif

#endif

slip.c

In line 853, just before

arr = check_realloc(arr, n2*sizeof(fftwf_complex));

insert

fftwf_destroy_plan(plan);

In line 883, change the 'fftwf_free(arr)' to 'free(arr)'; since arr was allocated using check_malloc it should be freed with just free().

makefile

Edit the 2nd line that begins with OBJS so it contains

OBJS = iofunc.o misc.o slip.o ruptime.o srf_subs.o gslip_srf_subs.o geoproj_subs.o gslip_sliprate_subs.o wafront2d-rwg.o fourg.o

Delete the SRF_OBJS and FDRT_OBJS lines, 3-5.
Edit GETPARLIB and GETPARINC so it correctly points to the Getpar install in <CyberShake home>/software/Getpar .
Change CFLAGS to:
```
CFLAGS = ${UFLAGS} ${LF_FLAGS} 
```

Add:

# Uncomment for memcached support
MEMC = ../../../../../utils/libmemcached_1.0.18
CFLAGS := $(CFLAGS) -I${MEMC}/include -D_USE_MEMCACHED
LDLIBS := ${LDLIBS} -L${MEMC}/lib -lmemcached -L${OLCF_FFTW_ROOT}/lib

Delete all targets except genslip-v5.4.2, ${OBJS}, and clean.
Modify the genslip-v5.4.2 target. We need to remove unnecessary objects, and compile it to an object rather than an executable for inclusion in the genslip library. It should look like:

genslip-v5.4.2.o : genslip-v5.4.2.c ${OBJS}
        ${CC} ${CFLAGS} -c -o genslip-v5.4.2.o genslip-v5.4.2.c ${LDLIBS}

gslip_srf_subs.c

In line 175, add initialization for srf.np_seg, so we can free it without worry:

if (strcmp(srf[0].version, "2.0")==0) {
        srf[0].np_seg = NULL;
        srf[0].srf_hcmnt.cbuf = NULL;
}

Enclose lines 1166-1180 in an if statement:

if (strcmp(srf[0].version, "2.0")==0) {
        srf[0].srf_hcmnt.nline = 0;
        /*
        srf[0].nseg = 1;
        srf[0].np_seg = (int *)check_malloc((srf[0].nseg)*sizeof(int));
        srf[0].np_seg[0] = srf[0].srf_apnts.np;
        */

        /* 2018-04-02 updated for multiple segs */
        srf[0].nseg = srf[0].srf_prect.nseg;
        srf[0].np_seg = (int *)check_malloc((srf[0].nseg)*sizeof(int));

        for(iseg=0;iseg<nseg;iseg++)
           srf[0].np_seg[iseg] = prseg_ptr[iseg].nstk*prseg_ptr[0].ndip;

        /* end version 2.0 stuff, just in case */
}

iofunc.c

In line 179, change the function name read_ruppars to _read_ruppars:

struct pointsource *_read_ruppars(char *file,struct pointsource *psrc,float *mag,int *nx,int *ny,float *dx,float *dy,float *dtop,float *stk,float *dip,float *elon,float *elat)

Add the function _mc_add_file to the end of the file:

#ifdef _USE_MEMCACHED
void _mc_add_file(char* filename, char** file_buffer, memcached_st* mst) {
        memcached_return ret;
        uint32_t flags = 0;

        FILE* fpr = fopfile(filename, "rb");
        //Get file size so we know how big to make the file buffer
        fseek(fpr, 0, SEEK_END);
        long file_length = ftell(fpr);
        fseek(fpr, 0, SEEK_SET);

                fprintf(stderr, "READ ERROR - %ld attempted %ld read.\n", file_length, read);
                exit(1);
        }
        char* file_key = check_malloc(sizeof(char) * (strlen(filename) + 4));
        char buffer[1000*1000];
        //Memcached thinks this is 1 MB
        int ONE_MB = 1000*1000;
        int i=0;
        while (i*ONE_MB < file_length) {
                int to_copy = ONE_MB;
                if (file_length - i*ONE_MB < ONE_MB) {
                        to_copy = file_length - i*ONE_MB;
                }
                sprintf(file_key, "%s.%d", filename, i);
                memcpy(buffer, (*file_buffer)+i*ONE_MB, to_copy);

                ret = memcached_set(mst, file_key, strlen(file_key), buffer, strlen(buffer), 0, flags);
                if (ret!=MEMCACHED_SUCCESS) {
                        printf("Caching of %s failed.\n", file_key);
                        printf("%s\n", memcached_strerror(mst, ret));
                        printf("value length: %d bytes\n", strlen(buffer));
                }
                i++;
                memset(buffer, '\0', ONE_MB);
        }
        //Commit number of parts
        int num_parts = i;
        char* parts_key = check_malloc(sizeof(char) * (strlen(filename) + 1));
        strcpy(parts_key, filename);
        ret = memcached_set(mst, parts_key, strlen(parts_key), (char*)(&num_parts), sizeof(int), 0, flags);
        if (ret!=MEMCACHED_SUCCESS) {
                printf("Caching of %s failed.\n", parts_key);
                printf("%s\n", memcached_strerror(mst, ret));
        }
        free(file_key);
        free(parts_key);
        fclose(fpr);
}

Add the definition of _mc_read_ruppars:

struct pointsource* _mc_read_ruppars(char *file,struct pointsource *psrc,float *mag,int *nx,int *ny,float *dx,float *dy,float *dtop,float *stk,float *dip,float *elon,float *elat, char* mc_server)

misc.c

In line 68, modify zapit to use a for-loop and specify a return type. The function should become:
```
void zapit(float* s,int n)
{
int i;
for (i=0; i<n; i++) {
        s[i] = 0.0;
}
```

Add the free_srf_ptrs function to clean up everything:

void free_srf_ptrs(struct standrupformat* srf) {
        struct srf_planerectangle srf_prect = srf->srf_prect;
        struct srf_allpoints srf_apnts = srf->srf_apnts;

genslip-v5.4.2.c

This is where the majority of changes are made to turn this into an API. I recommend having an original copy for reference.

Note that line numbers are approximate.

In line 352, change from

int main(int ac,char **av)

to

#ifdef _USE_MEMCACHED
int mc_genslip(int ac, char** av, rg_stats_t *stats, struct standrupformat* srf, int state, char* memcached_server)
#else
int genslip(int ac,char **av, rg_stats_t *stats, struct standrupformat* srf, int state)
#endif

In line 2394, change '&srf' to 'srf'.

In the for loop starting in line 2452, we replace some of these calculations with refactored ones to pull out constants and take advantage of FMA. Specifically, make the following changes:

Before the for loop, define the following variables:

float half_ddip = 0.5*ddip;
float half_dstk_minus_half_flen = 0.5*dstk - 0.5*flen;
float half_flen_plus_shypo = 0.5*flen + shypo;
y0 = (deep_vrdep1-dtop)/sin(avgdip*rperd);
float deep_alpha = 1.0 + (deep_vrdep1-deep_rup*deep_vrdep1)/(deep_vrdep2-deep_vrdep1);
float deep_const = (deep_rup - 1.0)/(deep_vrdep2-deep_vrdep1);

Replace

yy = (j + 0.5)*ddip;

with

yy = j*ddip + half_ddip;

Replace

xx = (i+0.5)*dstk - 0.5*flen;

with

xx = i*dstk + half_dstk_minus_half_flen;

Replace

hg = (gbnd[ig]-0.5*flen)-shypo;

with

hg = gbnd[ig] - half_flen_plus_shypo;

Replace

vrfac = 1.0 + (deep_vrup - 1.0)*((psrc[ip].dep)-deep_vrdep1)/(deep_vrdep2-deep_vrdep1);

with

vrfac = deep_alpha + deep_const*psrc[ip].dep;

In line 2573, after 'psrc[j].rupt = psrc[j].rupt - tsmin + rupture_delay;', add:
```

    continue;
}

In line 2631, remove:
```
 write2srf(srf,str,outbin);
```
Writing out SRFs is done by calling write_srf() on the srf object.

At the very end of the function, we want to free everything not needed by the SRF object. Add:

free(rvfac_seg);
free(gbnd);
free(gwid);
free(psrc);
free(psrc_orig);
free(slip_c);
free(rake_c);
free(tsfac1_c);

free(rough_c);
free(tsfac2_c);

free(vmod.dep);
free(vmod.mu);
free(vmod.invb2);
free(rvmod.vs);
free(rvmod.th);
free(rvmod.invb2);

return 0;

Once verification is complete, you may wish to comment out some of the print statements.

Function name changes

Since Rob uses some of the same helper functions in his genslip code as in his jbsim3d code, we prepend an underscore to some of the function names in the genslip library to avoid namespace conflicts when compiling DirectSynth.

From the src directory, run the following sed command

sed -i 's/<function name>/_<function name>/g' *.c *.h */*.c */*.h

for each of these function names:

fopfile
opfile_ro
opfile
croptrfile
reed
rite
check_malloc
check_realloc
sfrand
gaus_rand
zapit
set_ne
set_ll
init_plane_srf
load_slip_srf
load_rupt_srf
gen_2tri_stf
gen_brune_stf

This might accidentally convert a 'write' to 'w_rite'; fix that with

 sed -i 's/w_rite/write/g' *.c *.h */*.c */*.h

and also run (since Fortran function names can't start with an underscore, but are case insensitive):

sed -i 's/sort/sort1/g' */*.f
sed -i 's/SORT/SORT1/g' */*.f

Compiling

Go back into the src directory and try to compile it with 'make'.

With v5.4.2, we are not including the -fno-expensive-optimizations flag, since backwards compatibility with Blue Waters and Titan isn't an issue.
